The earliest known written records of the history of China date from as early as 1250 BC, from the Shang dynasty (c. 1600–1046 BC), during the king Wu Ding's reign,   who was mentioned as the twenty-first Shang king by the same.   Ancient historical texts such as the Book of Documents (early chapters, 11th century BC), the Records of the Grand Historian (c. 100 BC) and the Bamboo Annals (296 BC) mention and describe a Xia dynasty (c. 2070–1600 BC) before the Shang, but no writing is known from the period, and Shang writings do not indicate the existence of the Xia.  The Shang ruled in the Yellow River valley, which is commonly held to be the cradle of Chinese civilization. However, Neolithic civilizations originated at various cultural centers along both the Yellow River and Yangtze River. These Yellow River and Yangtze civilizations arose millennia before the Shang. With thousands of years of continuous history, China is one of the world's oldest civilizations,  and is regarded as one of the cradles of civilization. 
The Zhou dynasty (1046–256 BC) supplanted the Shang, and introduced the concept of the Mandate of Heaven to justify their rule. The central Zhou government began to weaken due to external and internal pressures in the 8th century BC, and the country eventually splintered into smaller states during the Spring and Autumn period. These states became independent and warred with one another in the following Warring States period. Much of traditional Chinese culture, literature and philosophy first developed during those troubled times.
In 221 BC, Qin Shi Huang conquered the various warring states and created for himself the title of Huangdi or " emperor" of the Qin, marking the beginning of imperial China. However, the oppressive government fell soon after his death, and was supplanted by the longer-lived Han dynasty (206 BC – 220 AD). Successive dynasties developed bureaucratic systems that enabled the emperor to control vast territories directly. In the 21 centuries from 206 BC until AD 1912, routine administrative tasks were handled by a special elite of scholar-officials. Young men, well-versed in calligraphy, history, literature, and philosophy, were carefully selected through difficult government examinations. China's last dynasty was the Qing (1644–1912), which was replaced by the Republic of China in 1912, and then in the mainland by the People's Republic of China in 1949.
Chinese history has alternated between periods of political unity and peace, and periods of war and failed statehood—the most recent being the Chinese Civil War (1927–1949). China was occasionally dominated by steppe peoples, most of whom were eventually assimilated into the Han Chinese culture and population. Between eras of multiple kingdoms and warlordism, Chinese dynasties have ruled parts or all of China; in some eras control stretched as far as Xinjiang and Tibet, as at present. Traditional culture, and influences from other parts of Asia and the Western world (carried by waves of immigration, cultural assimilation, expansion, and foreign contact), form the basis of the modern culture of China.
Paleolithic (3.3 Ma ~ 12 ka)
What is now China was inhabited by Homo erectus more than a million years ago.  Recent study shows that the stone tools found at Xiaochangliang site are magnetostratigraphically dated to 1.36 million years ago.  The archaeological site of Xihoudu in Shanxi Province has evidence of use of fire by Homo erectus,  which is dated 1.27 million years ago,  and Homo erectus fossils in China include the Yuanmou Man, the Lantian Man and the Peking Man. Fossilised teeth of Homo sapiens dating to 125,000–80,000 BC have been discovered in Fuyan Cave in Dao County in Hunan.  Evidence of Middle Palaeolithic Levallois technology has been found in the lithic assemblage of Guanyindong Cave site in southwest China, dated to approximately 170,000–80,000 years ago. 
The Neolithic age in China can be traced back to about 10,000 BC.  The earliest evidence of cultivated rice, found by the Yangtze River, is carbon-dated to 8,000 years ago.  Early evidence for proto-Chinese millet agriculture is radiocarbon-dated to about 7000 BC.  Farming gave rise to the Jiahu culture (7000 to 5800 BC). At Damaidi in Ningxia, 3,172 cliff carvings dating to 6000–5000 BC have been discovered, "featuring 8,453 individual characters such as the sun, moon, stars, gods and scenes of hunting or grazing".[ attribution needed] These pictographs are reputed to be similar to the earliest characters confirmed to be written Chinese.  Chinese proto-writing existed in Jiahu around 7000 BC,  Dadiwan from 5800 BC to 5400 BC, Damaidi around 6000 BC  and Banpo dating from the 5th millennium BC. Some scholars have suggested that Jiahu symbols (7th millennium BC) were the earliest Chinese writing system.  Excavation of a Peiligang culture site in Xinzheng county, Henan, found a community that flourished in 5,500 to 4,900 BC, with evidence of agriculture, constructed buildings, pottery, and burial of the dead.  With agriculture came increased population, the ability to store and redistribute crops, and the potential to support specialist craftsmen and administrators.  In late Neolithic times, the Yellow River valley began to establish itself as a center of Yangshao culture (5000 BC to 3000 BC), and the first villages were founded; the most archaeologically significant of these was found at Banpo, Xi'an.  Later, Yangshao culture was superseded by the Longshan culture, which was also centered on the Yellow River from about 3000 BC to 2000 BC.
Bronze artifacts have been found at the Majiayao culture site (between 3100 and 2700 BC).   The Bronze Age is also represented at the Lower Xiajiadian culture (2200–1600 BC ) site in northeast China. Sanxingdui located in what is now Sichuan province is believed to be the site of a major ancient city, of a previously unknown Bronze Age culture (between 2000 and 1200 BC). The site was first discovered in 1929 and then re-discovered in 1986. Chinese archaeologists have identified the Sanxingdui culture to be part of the ancient kingdom of Shu, linking the artifacts found at the site to its early legendary kings.  
Ferrous metallurgy begins to appear in the late 6th century in the Yangzi Valley.  A bronze tomahawk with a blade of meteoric iron excavated near the city of Gaocheng in Shijiazhuang (now Hebei province) has been dated to the 14th century BC. For this reason, authors such as Liana Chua and Mark Elliott have used the term "Iron Age" by convention for the transitional period of c. 500 BC to 100 BC, roughly corresponding to the Warring States period of Chinese historiography.  An Iron Age culture of the Tibetan Plateau has tentatively been associated with the Zhang Zhung culture described in early Tibetan writings.
Xia dynasty (2070–1600 BC)
The Xia dynasty of China (from c. 2070 to c. 1600 BC) is the first dynasty to be described in ancient historical records such as Sima Qian's Records of the Grand Historian and Bamboo Annals.  The dynasty was considered mythical by historians until scientific excavations found early Bronze Age sites at Erlitou, Henan in 1959.  With few clear records matching the Shang oracle bones, it remains unclear whether these sites are the remains of the Xia dynasty or of another culture from the same period.  Excavations that overlap the alleged time period of the Xia indicate a type of culturally similar groupings of chiefdoms. Early markings from this period found on pottery and shells are thought to be ancestral to modern Chinese characters. 
According to ancient records, the dynasty ended around 1600 BC as a consequence of the Battle of Mingtiao.
Shang dynasty (1600–1046 BC)
Archaeological findings providing evidence for the existence of the Shang dynasty, c. 1600–1046 BC, are divided into two sets. The first set, from the earlier Shang period, comes from sources at Erligang, Zhengzhou, and Shangcheng. The second set, from the later Shang or Yin (殷) period, is at Anyang, in modern-day Henan, which has been confirmed as the last of the Shang's nine capitals (c. 1300–1046 BC).[ citation needed] The findings at Anyang include the earliest written record of the Chinese so far discovered: inscriptions of divination records in ancient Chinese writing on the bones or shells of animals—the " oracle bones", dating from around 1250 BC. 
A series of thirty-one kings reigned over the Shang dynasty. During their reign, according to the Records of the Grand Historian, the capital city was moved six times.  The final (and most important) move was to Yin in around 1300 BC which led to the dynasty's golden age.  The term Yin dynasty has been synonymous with the Shang dynasty in history, although it has lately been used to refer specifically to the latter half of the Shang dynasty.
Chinese historians in later periods were accustomed to the notion of one dynasty succeeding another, but the political situation in early China was much more complicated. Hence, as some scholars of China suggest, the Xia and the Shang can refer to political entities that existed concurrently, just as the early Zhou existed at the same time as the Shang.[ citation needed]
Although written records found at Anyang confirm the existence of the Shang dynasty,  Western scholars are often hesitant to associate settlements that are contemporaneous with the Anyang settlement with the Shang dynasty. For example, archaeological findings at Sanxingdui suggest a technologically advanced civilization culturally unlike Anyang. The evidence is inconclusive in proving how far the Shang realm extended from Anyang. The leading hypothesis is that Anyang, ruled by the same Shang in the official history, coexisted and traded with numerous other culturally diverse settlements in the area that is now referred to as China proper.[ citation needed]
Zhou dynasty (1046–256 BC)
The Zhou dynasty (1046 BC to approximately 256 BC) is the longest-lasting dynasty in Chinese history. By the end of the 2nd millennium BC, the Zhou dynasty began to emerge in the Yellow River valley, overrunning the territory of the Shang. The Zhou appeared to have begun their rule under a semi-feudal system. The Zhou lived west of the Shang, and the Zhou leader was appointed Western Protector by the Shang. The ruler of the Zhou, King Wu, with the assistance of his brother, the Duke of Zhou, as regent, managed to defeat the Shang at the Battle of Muye.
The king of Zhou at this time invoked the concept of the Mandate of Heaven to legitimize his rule, a concept that was influential for almost every succeeding dynasty.[ citation needed] Like Shangdi, Heaven (tian) ruled over all the other gods, and it decided who would rule China.  It was believed that a ruler lost the Mandate of Heaven when natural disasters occurred in great number, and when, more realistically, the sovereign had apparently lost his concern for the people. In response, the royal house would be overthrown, and a new house would rule, having been granted the Mandate of Heaven.
The Zhou initially moved their capital west to an area near modern Xi'an, on the Wei River, a tributary of the Yellow River, but they would preside over a series of expansions into the Yangtze River valley. This would be the first of many population migrations from north to south in Chinese history.
Spring and Autumn period (722–476 BC)
This section does not cite any sources. (May 2018) ( Learn how and when to remove this template message)
In the 8th century BC, power became decentralized during the Spring and Autumn period, named after the influential Spring and Autumn Annals. In this period, local military leaders used by the Zhou began to assert their power and vie for hegemony. The situation was aggravated by the invasion of other peoples from the northwest, such as the Qin, forcing the Zhou to move their capital east to Luoyang. This marks the second major phase of the Zhou dynasty: the Eastern Zhou. The Spring and Autumn period is marked by a falling apart of the central Zhou power. In each of the hundreds of states that eventually arose, local strongmen held most of the political power and continued their subservience to the Zhou kings in name only. Some local leaders even started using royal titles for themselves. China now consisted of hundreds of states, some of them only as large as a village with a fort.
As the era continued, larger and more powerful states annexed or claimed suzerainty over smaller ones. By the 6th century BC most small states had disappeared by being annexed and just a few large and powerful principalities dominated China. Some southern states, such as Chu and Wu, claimed independence from the Zhou, who undertook wars against some of them (Wu and Yue). Many new cities were established in this period and Chinese culture was slowly shaped.
Once all these powerful rulers had firmly established themselves within their respective dominions, the bloodshed focused more fully on interstate conflict in the Warring States period, which began when the three remaining élite families in the Jin state—Zhao, Wei and Han—partitioned the state. Many famous individuals such as Laozi, Confucius and Sun Tzu lived during this chaotic period.
The Hundred Schools of Thought of Chinese philosophy blossomed during this period, and such influential intellectual movements as Confucianism, Taoism, Legalism and Mohism were founded, partly in response to the changing political world. The first two philosophical thoughts would have an enormous influence on Chinese culture.
Warring States period (476–221 BC)
After further political consolidation, seven prominent states remained by the end of the 5th century BC, and the years in which these few states battled each other are known as the Warring States period. Though there remained a nominal Zhou king until 256 BC, he was largely a figurehead and held little real power.
Numerous developments were made during this period in culture and mathematics. Examples include an important literary achievement, the Zuo zhuan on the Spring and Autumn Annals, which summarizes the preceding Spring and Autumn period, and the bundle of 21 bamboo slips from the Tsinghua collection, which was invented during this period dated to 305 BC, are the world's earliest example of a two digit decimal multiplication table, indicating that sophisticated commercial arithmetic was already established during this period. 
As neighboring territories of these warring states, including areas of modern Sichuan and Liaoning, were annexed, they were governed under the new local administrative system of commandery and prefecture. This system had been in use since the Spring and Autumn period, and parts can still be seen in the modern system of Sheng and Xian (province and county).
The final expansion in this period began during the reign of Ying Zheng, the king of Qin. His unification of the other six powers, and further annexations in the modern regions of Zhejiang, Fujian, Guangdong and Guangxi in 214 BC, enabled him to proclaim himself the First Emperor (Qin Shi Huang).
The Imperial China Period can be divided into three sub-periods: Early, Middle, and Late.
Major events in the Early sub-period include the Qin unification of China and their replacement by the Han, the First Split followed by the Jin unification, and the loss of north China. The Middle sub-period was marked by the Sui unification and their supplementation by the Tang, the Second Split, and the Song unification. The Late sub-period included the Yuan, Ming, and Qing dynasties.
Qin dynasty (221–207 BC)
Historians often refer to the period from the Qin dynasty to the end of the Qing dynasty as Imperial China. Though the unified reign of the First Qin Emperor lasted only 12 years, he managed to subdue great parts of what constitutes the core of the Han Chinese homeland and to unite them under a tightly centralized Legalist government seated at Xianyang (close to modern Xi'an). The doctrine of Legalism that guided the Qin emphasized strict adherence to a legal code and the absolute power of the emperor. This philosophy, while effective for expanding the empire in a military fashion, proved unworkable for governing it in peacetime. The Qin Emperor presided over the brutal silencing of political opposition, including the event known as the burning of books and burying of scholars. This would be the impetus behind the later Han synthesis incorporating the more moderate schools of political governance.
Major contributions of the Qin include the concept of a centralized government, and the unification and development of the legal code, the written language, measurement, and currency of China after the tribulations of the Spring and Autumn and Warring States periods. Even something as basic as the length of axles for carts—which need to match ruts in the roads—had to be made uniform to ensure a viable trading system throughout the empire. Also as part of its centralization, the Qin connected the northern border walls of the states it defeated, making the first Great Wall of China.
The tribes of the north, collectively called the Wu Hu by the Qin, were free from Chinese rule during the majority of the dynasty.  Prohibited from trading with Qin dynasty peasants, the Xiongnu tribe living in the Ordos region in northwest China often raided them instead, prompting the Qin to retaliate. After a military campaign led by General Meng Tian, the region was conquered in 215 BC and agriculture was established; the peasants, however, were discontented and later revolted. The succeeding Han dynasty also expanded into the Ordos due to overpopulation, but depleted their resources in the process. Indeed, this was true of the dynasty's borders in multiple directions; modern Inner Mongolia, Xinjiang, Tibet, Manchuria, and regions to the southeast were foreign to the Qin, and even areas over which they had military control were culturally distinct. 
As early as Confucius and up until 1912, there was reliance upon a trained intellectual elite, the scholar-official ("scholar-gentlemen").  They were civil servants appointed by the Emperor to handle daily governance. Talented young men were selected through an elaborate process of imperial examination. They had to demonstrate skill at calligraphy, and had to know Confucian philosophy. Historian Wing-Tsit Chan concludes that:
Generally speaking, the record of these scholar-gentlemen has been a worthy one. It was good enough to be praised and imitated in 18th century Europe. Nevertheless, it has given China a tremendous handicap in their transition from government by men to government by law, and personal considerations in Chinese government have been a curse.
After Emperor Qin Shi Huang's unnatural death due to the consumption of mercury pills,  the Qin government drastically deteriorated and eventually capitulated in 207 BC after the Qin capital was captured and sacked by rebels, which would ultimately lead to the establishment of a new dynasty of a unified China.  Despite the short 15-year duration of the Qin dynasty, it was immensely influential on China and the structure of future Chinese dynasties.
Han dynasty (202 BC – AD 220)
The Han dynasty was founded by Liu Bang, who emerged victorious in the Chu–Han Contention that followed the fall of the Qin dynasty. A golden age in Chinese history, the Han dynasty's long period of stability and prosperity consolidated the foundation of China as a unified state under a central imperial bureaucracy, which was to last intermittently for most of the next two millennia. During the Han dynasty, territory of China was extended to most of the China proper and to areas far west. Confucianism was officially elevated to orthodox status and was to shape the subsequent Chinese civilization. Art, culture and science all advanced to unprecedented heights. With the profound and lasting impacts of this period of Chinese history, the dynasty name "Han" had been taken as the name of the Chinese people, now the dominant ethnic group in modern China, and had been commonly used to refer to Chinese language and written characters. The Han dynasty also saw many mathematical innovations being invented such as the method of Gaussian elimination which appeared in the Chinese mathematical text Chapter Eight Rectangular Arrays of The Nine Chapters on the Mathematical Art. Its use is illustrated in eighteen problems, with two to five equations. The first reference to the book by this title is dated to 179 AD, but parts of it were written as early as approximately 150 BC, more than 1500 years before the Europeans came up with the method in the 18th century.  
After the initial laissez-faire policies of Emperors Wen and Jing, the ambitious Emperor Wu brought the empire to its zenith. To consolidate his power, Confucianism, which emphasizes stability and order in a well-structured society, was given exclusive patronage to be the guiding philosophical thoughts and moral principles of the empire. Imperial Universities were established to support its study and further development, while other schools of thought were discouraged.
Major military campaigns were launched to weaken the nomadic Xiongnu Empire, limiting their influence north of the Great Wall. Along with the diplomatic efforts led by Zhang Qian, the sphere of influence of the Han Empire extended to the states in the Tarim Basin, opened up the Silk Road that connected China to the west, stimulating bilateral trade and cultural exchange. To the south, various small kingdoms far beyond the Yangtze River Valley were formally incorporated into the empire.
Emperor Wu also dispatched a series of military campaigns against the Baiyue tribes. The Han annexed Minyue in 135 BC and 111 BC, Nanyue in 111 BC, and Dian in 109 BC.  Migration and military expeditions led to the cultural assimilation of the south.  It also brought the Han into contact with kingdoms in Southeast Asia, introducing diplomacy and trade. 
After Emperor Wu, the empire slipped into gradual stagnation and decline. Economically, the state treasury was strained by excessive campaigns and projects, while land acquisitions by elite families gradually drained the tax base. Various consort clans exerted increasing control over strings of incompetent emperors and eventually the dynasty was briefly interrupted by the usurpation of Wang Mang.
In AD 9, the usurper Wang Mang claimed that the Mandate of Heaven called for the end of the Han dynasty and the rise of his own, and he founded the short-lived Xin ("New") dynasty. Wang Mang started an extensive program of land and other economic reforms, including the outlawing of slavery and land nationalization and redistribution. These programs, however, were never supported by the landholding families, because they favored the peasants. The instability of power brought about chaos, uprisings, and loss of territories. This was compounded by mass flooding of the Yellow River; silt buildup caused it to split into two channels and displaced large numbers of farmers. Wang Mang was eventually killed in Weiyang Palace by an enraged peasant mob in AD 23.
Emperor Guangwu reinstated the Han dynasty with the support of landholding and merchant families at Luoyang, east of the former capital Xi'an. Thus, this new era is termed the Eastern Han dynasty. With the capable administrations of Emperors Ming and Zhang, former glories of the dynasty was reclaimed, with brilliant military and cultural achievements. The Xiongnu Empire was decisively defeated. The diplomat and general Ban Chao further expanded the conquests across the Pamirs to the shores of the Caspian Sea,  thus reopening the Silk Road, and bringing trade, foreign cultures, along with the arrival of Buddhism. With extensive connections with the west, the first of several Roman embassies to China were recorded in Chinese sources, coming from the sea route in AD 166, and a second one in AD 284.
The Eastern Han dynasty was one of the most prolific era of science and technology in ancient China, notably the historic invention of papermaking by Cai Lun, and the numerous scientific and mathematical contributions by the famous polymath Zhang Heng.
Three Kingdoms (AD 220–280)
By the 2nd century, the empire declined amidst land acquisitions, invasions, and feuding between consort clans and eunuchs. The Yellow Turban Rebellion broke out in AD 184, ushering in an era of warlords. In the ensuing turmoil, three states tried to gain predominance in the period of the Three Kingdoms. This time period has been greatly romanticized in works such as Romance of the Three Kingdoms.
After Cao Cao reunified the north in 208, his son proclaimed the Wei dynasty in 220. Soon, Wei's rivals Shu and Wu proclaimed their independence, leading China into the Three Kingdoms period. This period was characterized by a gradual decentralization of the state that had existed during the Qin and Han dynasties, and an increase in the power of great families.
In 266, the Jin dynasty overthrew the Wei and later unified the country in 280, but this union was short-lived.
Jin dynasty (AD 266–420)
The Jin dynasty was severely weakened by internecine fighting among imperial princes and lost control of northern China after non-Han Chinese settlers rebelled and captured Luoyang and Chang'an. In 317, a Jin prince in modern-day Nanjing became emperor and continued the dynasty, now known as the Eastern Jin, which held southern China for another century. Prior to this move, historians refer to the Jin dynasty as the Western Jin.
Northern China fragmented into a series of independent kingdoms, most of which were founded by Xiongnu, Xianbei, Jie, Di and Qiang rulers. These non-Han peoples were ancestors of the Turks, Mongols, and Tibetans. Many had, to some extent, been " sinicized" long before their ascent to power. In fact, some of them, notably the Qiang and the Xiongnu, had already been allowed to live in the frontier regions within the Great Wall since late Han times. During the period of the Sixteen Kingdoms, warfare ravaged the north and prompted large-scale Han Chinese migration south to the Yangtze River Basin and Delta.
Northern and Southern dynasties (AD 420–589)
This section does not cite any sources. (May 2018) ( Learn how and when to remove this template message)
In the early 5th century, China entered a period known as the Northern and Southern dynasties, in which parallel regimes ruled the northern and southern halves of the country. In the south, the Eastern Jin gave way to the Liu Song, Southern Qi, Liang and finally Chen. Each of these Southern dynasties were led by Han Chinese ruling families and used Jiankang (modern Nanjing) as the capital. They held off attacks from the north and preserved many aspects of Chinese civilization, while northern barbarian regimes began to sinify.
In the north, the last of the Sixteen Kingdoms was extinguished in 439 by the Northern Wei, a kingdom founded by the Xianbei, a nomadic people who unified northern China. The Northern Wei eventually split into the Eastern and Western Wei, which then became the Northern Qi and Northern Zhou. These regimes were dominated by Xianbei or Han Chinese who had married into Xianbei families. During this period most Xianbei people adopted Han surnames, eventually leading to complete assimilation into the Han.
Despite the division of the country, Buddhism spread throughout the land. In southern China, fierce debates about whether Buddhism should be allowed were held frequently by the royal court and nobles. By the end of the era, Buddhists and Taoists had become much more tolerant of each other.
Sui dynasty (AD 581–618)
The short-lived Sui dynasty was a pivotal period in Chinese history. Founded by Emperor Wen in 581 in succession of the Northern Zhou, the Sui went on to conquer the Southern Chen in 589 to reunify China, ending three centuries of political division. The Sui pioneered many new institutions, including the government system of Three Departments and Six Ministries, imperial examinations for selecting officials from commoners, while improved on the systems of fubing system of the army conscription and the Equal-field system of land distributions. These policies, which were adopted by later dynasties, brought enormous population growth, and amassed excessive wealth to the state. Standardized coinage were enforced throughout the unified empire. Buddhism took root as a prominent religion and was supported officially. Sui China was known for its numerous mega-construction projects. Intended for grains shipment and transporting troops, the Grand Canal was constructed, linking the capitals Daxing (Chang'an) and Luoyang to the wealthy southeast region, and in another route, to the northeast border. The Great Wall was also expanded, while series of military conquests and diplomatic maneuvers further pacified its borders. However, the massive invasions of the Korean Peninsula during the Goguryeo–Sui War failed disastrously, triggering widespread revolts that led to the fall of the dynasty.
Tang dynasty (AD 618–907)
The Tang dynasty was founded by Emperor Gaozu on 18 June 618. It was a golden age of Chinese civilization and considered to be the most prosperous period of China with significant developments in culture, art, literature, particularly poetry, and technology. Buddhism became the predominant religion for the common people. Chang'an (modern Xi'an), the national capital, was the largest city in the world during its time. 
The second emperor, Taizong, is widely regarded as one of the greatest emperors in Chinese history, who had laid the foundation for the dynasty to flourish for centuries beyond his reign. Combined military conquests and diplomatic maneuvers were implemented to eliminate threats from nomadic tribes, extend the border, and submit neighboring states into a tributary system. Military victories in the Tarim Basin kept the Silk Road open, connecting Chang'an to Central Asia and areas far to the west. In the south, lucrative maritime trade routes began from port cities such as Guangzhou. There was extensive trade with distant foreign countries, and many foreign merchants settled in China, encouraging a cosmopolitan culture. The Tang culture and social systems were observed and imitated by neighboring countries, most notably, Japan. Internally the Grand Canal linked the political heartland in Chang'an to the agricultural and economic centers in the eastern and southern parts of the empire. Xuanzang, a Chinese Buddhist monk, scholar, traveller, and translator who travelled to India on his own, and returned with, "over six hundred Mahayana and Hinayana texts, seven statues of the Buddha and more than a hundred sarira relics."
Underlying the prosperity of the early Tang dynasty was a strong centralized bureaucracy with efficient policies. The government was organized as " Three Departments and Six Ministries" to separately draft, review, and implement policies. These departments were run by royal family members as well as scholar officials who were selected by imperial examinations. These practices, which matured in the Tang dynasty, were continued by the later dynasties, with some modifications.
Under the Tang " equal-field system" all land was owned by the Emperor and granted to people according to household size. Men granted land were conscripted for military service for a fixed period each year, a military policy known as the " Fubing system". These policies stimulated a rapid growth in productivity and a significant army without much burden on the state treasury. By the dynasty's midpoint, however, standing armies had replaced conscription, and land was continuously falling into the hands of private owners.
The dynasty continued to flourish under the rule of Empress Wu Zetian, the only empress regnant in Chinese history, and reached its zenith during the long reign of Emperor Xuanzong, who oversaw an empire that stretched from the Pacific to the Aral Sea with at least 50 million people. There were vibrant artistic and cultural creations, including works of the greatest Chinese poets, Li Bai, and Du Fu.
At the zenith of prosperity of the empire, the An Lushan Rebellion from 755 to 763 was a watershed event that devastated the population and drastically weakened the central imperial government. Upon suppression of the rebellion, regional military governors, known as Jiedushi, gained increasingly autonomous status. With loss of revenue from land tax, the central imperial government relied heavily on salt monopoly. Externally, former submissive states raided the empire and the vast border territories were irreversibly lost for subsequent centuries. Nevertheless, civil society recovered and thrived amidst the weakened imperial bureaucracy.
In late Tang period, the empire was worn out by recurring revolts of regional warlords, while internally, as scholar-officials engaged in fierce factional strife, corrupted eunuchs amassed immense power. Catastrophically, the Huang Chao Rebellion, from 874 to 884, devastated the entire empire for a decade. The sack of the southern port Guangzhou in 879 was followed by the massacre of most of its inhabitants, along with the large foreign merchant enclaves.   By 881, both capitals, Luoyang and Chang'an, fell successively. The reliance on ethnic Han and Turkic warlords in suppressing the rebellion increased their power and influence. Consequently, the fall of the dynasty following Zhu Wen's usurpation led to an era of division.
According to historian Mark Edward Lewis:
- Most Chinese regard the Tang dynasty (618–907) as the high point of Imperial China, both politically and culturally. The empire reached its greatest size prior to the Manchu Qing dynasty, becoming the center of an East Asian world linked by religion, script, and many economic and political institutions. Moreover, Tang writers produce the finest poetry in China's great lyric tradition. 
Five Dynasties and Ten Kingdoms (AD 907–960)
The period of political disunity between the Tang and the Song, known as the Five Dynasties and Ten Kingdoms period, lasted from 907 to 960. During this half-century, China was in all respects a multi-state system. Five regimes, namely, (Later) Liang, Tang, Jin, Han and Zhou, rapidly succeeded one another in control of the traditional Imperial heartland in northern China. Among the regimes, rulers of (Later) Tang, Jin and Han were sinicized Shatuo Turks, which ruled over the ethnic majority of Han Chinese. More stable and smaller regimes of mostly ethnic Han rulers coexisted in south and western China over the period, cumulatively constituted the "Ten Kingdoms".
Amidst political chaos in the north, the strategic Sixteen Prefectures (region along today's Great Wall) were ceded to the emerging Khitan Liao dynasty, which drastically weakened the defense of the China proper against northern nomadic empires. To the south, Vietnam gained lasting independence after being a Chinese prefecture for many centuries. With wars dominated in Northern China, there were mass southward migrations of population, which further enhanced the southward shift of cultural and economic centers in China. The era ended with the coup of Later Zhou general Zhao Kuangyin, and the establishment of the Song dynasty in 960, which eventually annihilated the remains of the "Ten Kingdoms" and reunified China.
Song, Liao, Jin, and Western Xia dynasties (AD 960–1234)
In 960, the Song dynasty was founded by Emperor Taizu, with its capital established in Kaifeng (also known as Bianjing). In 979, the Song dynasty reunified most of the China proper, while large swaths of the outer territories were occupied by sinicized nomadic empires. The Khitan Liao dynasty, which lasted from 907 to 1125, ruled over Manchuria, Mongolia, and parts of Northern China. Meanwhile, in what are now the north-western Chinese provinces of Gansu, Shaanxi, and Ningxia, the Tangut tribes founded the Western Xia dynasty from 1032 to 1227.
Aiming to recover the strategic Sixteen Prefectures lost in the previous dynasty, campaigns were launched against the Liao dynasty in the early Song period, which all ended in failure. Then in 1004, the Liao cavalry swept over the exposed North China Plain and reached the outskirts of Kaifeng, forcing the Song's submission and then agreement to the Chanyuan Treaty, which imposed heavy annual tributes from the Song treasury. The treaty was a significant reversal of Chinese dominance of the traditional tributary system. Yet the annual outflow of Song's silver to the Liao was paid back through the purchase of Chinese goods and products, which expanded the Song economy, and replenished its treasury. This dampened the incentive for the Song to further campaign against the Liao. Meanwhile, this cross-border trade and contact induced further sinicization within the Liao Empire, at the expense of its military might which was derived from its primitive nomadic lifestyle. Similar treaties and social-economical consequences occurred in Song's relations with the Jin dynasty.
Within the Liao Empire, the Jurchen tribes revolted against their overlords to establish the Jin dynasty in 1115. In 1125, the devastating Jin cataphract annihilated the Liao dynasty, while remnants of Liao court members fled to Central Asia to found the Qara Khitai Empire (Western Liao dynasty). Jin's invasion of the Song dynasty followed swiftly. In 1127, Kaifeng was sacked, a massive catastrophe known as the Jingkang Incident, ending the Northern Song dynasty. Later the entire north of China was conquered. The survived members of Song court regrouped in the new capital city of Hangzhou, and initiated the Southern Song dynasty, which ruled territories south of the Huai River. In the ensuing years, the territory and population of China were divided between the Song dynasty, the Jin dynasty and the Western Xia dynasty. The era ended with the Mongol conquest, as Western Xia fell in 1227, the Jin dynasty in 1234, and finally the Southern Song dynasty in 1279.
Despite its military weakness, the Song dynasty is widely considered to be the high point of classical Chinese civilization. The Song economy, facilitated by technology advancement, had reached a level of sophistication probably unseen in world history before its time. The population soared to over 100 million and the living standards of common people improved tremendously due to improvements in rice cultivation and the wide availability of coal for production. The capital cities of Kaifeng and subsequently Hangzhou were both the most populous cities in the world for their time, and encouraged vibrant civil societies unmatched by previous Chinese dynasties. Although land trading routes to the far west were blocked by nomadic empires, there were extensive maritime trade with neighboring states, which facilitated the use of Song coinage as the de facto currency of exchange. Giant wooden vessels equipped with compasses traveled throughout the China Seas and northern Indian Ocean. The concept of insurance was practised by merchants to hedge the risks of such long-haul maritime shipments. With prosperous economic activities, the historically first use of paper currency emerged in the western city of Chengdu, as a supplement to the existing copper coins.
The Song dynasty was considered to be the golden age of great advancements in science and technology of China, thanks to innovative scholar-officials such as Su Song (1020–1101) and Shen Kuo (1031–1095). Inventions such as the hydro-mechanical astronomical clock, the first continuous and endless power-transmitting chain, woodblock printing and paper money were all invented during the Song dynasty.
There was court intrigue between the political reformers and conservatives, led by the chancellors Wang Anshi and Sima Guang, respectively. By the mid-to-late 13th century, the Chinese had adopted the dogma of Neo-Confucian philosophy formulated by Zhu Xi. Enormous literary works were compiled during the Song dynasty, such as the historical work, the Zizhi Tongjian ("Comprehensive Mirror to Aid in Government"). The invention of movable-type printing further facilitated the spread of knowledge. Culture and the arts flourished, with grandiose artworks such as Along the River During the Qingming Festival and Eighteen Songs of a Nomad Flute, along with great Buddhist painters such as the prolific Lin Tinggui.
The Song dynasty was also a period of major innovation in the history of warfare. Gunpowder, while invented in the Tang dynasty, was first put into use in battlefields by the Song army, inspiring a succession of new firearms and siege engines designs. During the Southern Song dynasty, as its survival hinged decisively on guarding the Yangtze and Huai River against the cavalry forces from the north, the first standing navy in China was assembled in 1132, with its admiral's headquarters established at Dinghai. Paddle-wheel warships equipped with trebuchets could launch incendiary bombs made of gunpowder and lime, as recorded in Song's victory over the invading Jin forces at the Battle of Tangdao in the East China Sea, and the Battle of Caishi on the Yangtze River in 1161.
The advances in civilization during the Song dynasty came to an abrupt end following the devastating Mongol conquest, during which the population sharply dwindled, with a marked contraction in economy. Despite viciously halting Mongol advance for more than three decades, the Southern Song capital Hangzhou fell in 1276, followed by the final annihilation of the Song standing navy at the Battle of Yamen in 1279.
Yuan dynasty (AD 1271–1368)
The Yuan dynasty was formally proclaimed in 1271, when the Great Khan of Mongol, Kublai Khan, one of the grandsons of Genghis Khan, assumed the additional title of Emperor of China, and considered his inherited part of the Mongol Empire as a Chinese dynasty. In the preceding decades, the Mongols had conquered the Jin dynasty in Northern China, and the Southern Song dynasty fell in 1279 after a protracted and bloody war. The Mongol Yuan dynasty became the first conquest dynasty in Chinese history to rule the entire China proper and its population as an ethnic minority. The dynasty also directly controlled the Mongolian heartland and other regions, inheriting the largest share of territory of the divided Mongol Empire, which roughly coincided with the modern area of China and nearby regions in East Asia. Further expansion of the empire was halted after defeats in the invasions of Japan and Vietnam. Following the previous Jin dynasty, the capital of Yuan dynasty was established at Khanbaliq (also known as Dadu, modern-day Beijing). The Grand Canal was reconstructed to connect the remote capital city to economic hubs in southern part of China, setting the precedence and foundation where Beijing would largely remain as the capital of the successive regimes that unified China mainland.
After the peace treaty in 1304 that ended a series of Mongol civil wars, the emperors of the Yuan dynasty were upheld as the nominal Great Khan ( Khagan) of the greater Mongol Empire over other Mongol Khanates, which nonetheless remained de facto autonomous. The era was known as Pax Mongolica, when much of the Asian continent was ruled by the Mongols. For the first and only time in history, the silk road was controlled entirely by a single state, facilitating the flow of people, trade, and cultural exchange. Network of roads and a postal system were established to connect the vast empire. Lucrative maritime trade, developed from the previous Song dynasty, continued to flourish, with Quanzhou and Hangzhou emerging as the largest ports in the world. Adventurous travelers from the far west, most notably the Venetian, Marco Polo, would have settled in China for decades. Upon his return, his detail travel record inspired generations of medieval Europeans with the splendors of the far East. The Yuan dynasty was the first ancient economy, where paper currency, known at the time as Jiaochao, was used as the predominant medium of exchange. Its unrestricted issuance in the late Yuan dynasty inflicted hyperinflation, which eventually brought the downfall of the dynasty.
While the Mongol rulers of the Yuan dynasty adopted substantially to Chinese culture, their sinicization was of lesser extent compared to earlier conquest dynasties in Chinese history. For preserving racial superiority as the conqueror and ruling class, traditional nomadic customs and heritage from the Mongolian steppe were held in high regard. On the other hand, the Mongol rulers also adopted flexibly to a variety of cultures from many advanced civilizations within the vast empire. Traditional social structure and culture in China underwent immense transform during the Mongol dominance. Large group of foreign migrants settled in China, who enjoyed elevated social status over the majority Han Chinese, while enriching Chinese culture with foreign elements. The class of scholar officials and intellectuals, traditional bearers of elite Chinese culture, lost substantial social status. This stimulated the development of culture of the common folks. There were prolific works in zaju variety shows and literary songs ( sanqu), which were written in a distinctive poetry style known as qu. Novels of vernacular style gained unprecedented status and popularity.
Before the Mongol invasion, Chinese dynasties reported approximately 120 million inhabitants; after the conquest had been completed in 1279, the 1300 census reported roughly 60 million people.  This major decline is not necessarily due only to Mongol killings. Scholars such as Frederick W. Mote argue that the wide drop in numbers reflects an administrative failure to record rather than an actual decrease; others such as Timothy Brook argue that the Mongols created a system of enserfment among a huge portion of the Chinese populace, causing many to disappear from the census altogether; other historians including William McNeill and David Morgan consider that plague was the main factor behind the demographic decline during this period. In the 14th century China suffered additional depredations from epidemics of plague, estimated to have killed 25 million people, 30% of the population of China. 
Throughout the Yuan dynasty, there was some general sentiment among the populace against the Mongol dominance. Yet rather than the nationalist cause, it was mainly strings of natural disasters and incompetent governance that triggered widespread peasant uprisings since the 1340s. After the massive naval engagement at Lake Poyang, Zhu Yuanzhang prevailed over other rebel forces in the south. He proclaimed himself emperor and founded the Ming dynasty in 1368. The same year his northern expedition army captured the capital Khanbaliq. The Yuan remnants fled back to Mongolia and sustained the regime. Other Mongol Khanates in Central Asia continued to exist after the fall of Yuan dynasty in China.
Ming dynasty (AD 1368–1644)
The Ming dynasty was founded by Zhu Yuanzhang in 1368, who proclaimed himself as the Hongwu Emperor. The capital was initially set at Nanjing, and was later moved to Beijing from Yongle Emperor's reign onward.
Urbanization increased as the population grew and as the division of labor grew more complex. Large urban centers, such as Nanjing and Beijing, also contributed to the growth of private industry. In particular, small-scale industries grew up, often specializing in paper, silk, cotton, and porcelain goods. For the most part, however, relatively small urban centers with markets proliferated around the country. Town markets mainly traded food, with some necessary manufactures such as pins or oil.
Despite the xenophobia and intellectual introspection characteristic of the increasingly popular new school of neo-Confucianism, China under the early Ming dynasty was not isolated. Foreign trade and other contacts with the outside world, particularly Japan, increased considerably. Chinese merchants explored all of the Indian Ocean, reaching East Africa with the voyages of Zheng He.
The Hongwu Emperor, being the only founder of a Chinese dynasty who was also of peasant origin, had laid the foundation of a state that relied fundamentally in agriculture. Commerce and trade, which flourished in the previous Song and Yuan dynasties, were less emphasized. Neo-feudal landholdings of the Song and Mongol periods were expropriated by the Ming rulers. Land estates were confiscated by the government, fragmented, and rented out. Private slavery was forbidden. Consequently, after the death of the Yongle Emperor, independent peasant landholders predominated in Chinese agriculture. These laws might have paved the way to removing the worst of the poverty during the previous regimes. Towards later era of the Ming dynasty, with declining government control, commerce, trade and private industries revived.
The dynasty had a strong and complex central government that unified and controlled the empire. The emperor's role became more autocratic, although Hongwu Emperor necessarily continued to use what he called the " Grand Secretariat" to assist with the immense paperwork of the bureaucracy, including memorials (petitions and recommendations to the throne), imperial edicts in reply, reports of various kinds, and tax records. It was this same bureaucracy that later prevented the Ming government from being able to adapt to changes in society, and eventually led to its decline.
The Yongle Emperor strenuously tried to extend China's influence beyond its borders by demanding other rulers send ambassadors to China to present tribute. A large navy was built, including four-masted ships displacing 1,500 tons. A standing army of 1 million troops was created. The Chinese armies conquered and occupied Vietnam for around 20 years, while the Chinese fleet sailed the China seas and the Indian Ocean, cruising as far as the east coast of Africa. The Chinese gained influence in eastern Moghulistan. Several maritime Asian nations sent envoys with tribute for the Chinese emperor. Domestically, the Grand Canal was expanded and became a stimulus to domestic trade. Over 100,000 tons of iron per year were produced. Many books were printed using movable type. The imperial palace in Beijing's Forbidden City reached its current splendor. It was also during these centuries that the potential of south China came to be fully exploited. New crops were widely cultivated and industries such as those producing porcelain and textiles flourished.
In 1449 Esen Tayisi led an Oirat Mongol invasion of northern China which culminated in the capture of the Zhengtong Emperor at Tumu. Since then, the Ming became on the defensive on the northern frontier, which led to the Ming Great Wall being built. Most of what remains of the Great Wall of China today was either built or repaired by the Ming. The brick and granite work was enlarged, the watchtowers were redesigned, and cannons were placed along its length.
At sea, the Ming became increasingly isolationist after the death of the Yongle Emperor. The treasure voyages which sailed Indian Ocean were discontinued, and the maritime prohibition laws were set in place banning the Chinese from sailing abroad. European traders who reached China in the midst of the Age of Discovery were repeatedly rebuked in their requests for trade, with the Portuguese being repulsed by the Ming navy at Tuen Mun in 1521 and again in 1522. Domestic and foreign demands for overseas trade, deemed illegal by the state, led to widespread wokou piracy attacking the southeastern coastline during the rule of the Jiajing Emperor (1507–1567), which only subsided after the opening of ports in Guangdong and Fujian and much military suppression.  The Portuguese were allowed to settle in Macau in 1557 for trade, which remained in Portuguese hands until 1999. The Dutch entry into the Chinese seas was also met with fierce resistance, with the Dutch being chased off the Penghu islands in the Sino-Dutch conflicts of 1622–1624 and were forced to settle in Taiwan instead. The Dutch in Taiwan fought with the Ming in the Battle of Liaoluo Bay in 1633 and lost, and eventually surrendered to the Ming loyalist Koxinga in 1662, after the fall of the Ming dynasty.
The Ming dynasty intervened deeply in the Japanese invasions of Korea (1592–98), which ended with the withdrawal of all invading Japanese forces in Korea, and the restoration of the Joseon dynasty, its traditional ally and tributary state. The regional hegemony of the Ming dynasty was preserved at a toll on its resources. Coincidentally, with Ming's control in Manchuria in decline, the Manchu ( Jurchen) tribes, under their chieftain Nurhaci, broke away from Ming's rule, and emerged as a powerful, unified state, which was later proclaimed as the Qing dynasty. It went on to subdue the much weakened Korea as its tributary, conquered Mongolia, and expanded its territory to the outskirt of the Great Wall. The most elite army of the Ming dynasty was to station at the Shanhai Pass to guard the last stronghold against the Manchus, which weakened its suppression of internal peasants uprisings.
Qing dynasty (AD 1644–1911)
The Qing dynasty (1644–1911) was the last imperial dynasty in China. Founded by the Manchus, it was the second conquest dynasty to rule the territory of China proper, and roughly doubled the territory controlled by the Ming. The Manchus were formerly known as Jurchens, residing in the northeastern part of the Ming territory outside the Great Wall. They emerged as the major threat to the late Ming dynasty after Nurhaci united all Jurchen tribes and declared the founding of the Qing dynasty in 1636. The Qing dynasty set up the Eight Banners system that provided the basic framework for the Qing military conquest. Li Zicheng's peasant rebellion captured Beijing in 1644 and the Chongzhen Emperor, the last Ming emperor, committed suicide. The Manchus allied with the Ming general Wu Sangui to seize Beijing, which was made the capital of the Qing dynasty. and then proceeded to subdue the Ming remnants in the south. The decades of Manchu conquest caused enormous loss of lives and the economic scale of China shrank drastically. In total, the Qing conquest of the Ming (1618–1683) cost as many as 25 million lives.  The early Manchu emperors combined traditions of Central Asian rule with Confucian norms of traditional Chinese government and were considered a Chinese dynasty.
The Manchus enforced a 'queue order,' forcing Han Chinese men to adopt the Manchu queue hairstyle. Officials were required to wear Manchu-style clothing Changshan ( bannermen dress and Tangzhuang), but ordinary Han civilians were allowed to wear traditional Han clothing. Bannermen could not undertake trade or manual labor; they had to petition to be removed from banner status. They were considered a form of nobility and were given annual pensions, land, and allotments of cloth.The Kangxi Emperor ordered the creation of the Kangxi Dictionary, the most complete dictionary of Chinese characters that had been compiled.
Over the next half-century, all areas previously under the Ming dynasty were consolidated under the Qing. conquests in Central Asia in the eighteenth century extended territorial control. Between 1673 and 1681, the Kangxi Emperor suppressed the Revolt of the Three Feudatories, an uprising of three generals in Southern China who had been denied hereditary rule of large fiefdoms granted by the previous emperor. In 1683, the Qing staged an amphibious assault on southern Taiwan, bringing down the rebel Kingdom of Tungning, which was founded by the Ming loyalist Koxinga (Zheng Chenggong) in 1662 after the fall of the Southern Ming, and had served as a base for continued Ming resistance in Southern China. The Qing defeated the Russians at Albazin, resulting in the Treaty of Nerchinsk.
By the end of Qianlong Emperor's long reign in 1796, the Qing Empire was at its zenith. The Qing ruled more than one-third of the world's population, and had the largest economy in the world. By area it was one of the largest empires ever.
In the 19th century the empire was internally restive and externally threatened by western powers. The defeat by the British Empire in the First Opium War (1840) led to the Treaty of Nanking (1842), under which Hong Kong was ceded to Britain and importation of opium (produced by British Empire territories) was allowed. Opium usage continued to grow in China, adversely affecting societal stability. Subsequent military defeats and unequal treaties with other western powers continued even after the fall of the Qing dynasty.
Internally the Taiping Rebellion (1851–1864), a Christian religious movement led by the "Heavenly King" Hong Xiuquan swept from the south to establish the Taiping Heavenly Kingdom and controlled roughly a third of China proper for over a decade. The court in desperation empowered Han Chinese officials such as Zeng Guofan to raise local armies. After initial defeats, Zeng crushed the rebels in the Third Battle of Nanking in 1864.  This was one of the largest wars in the 19th century in terms of troop involvement; there was massive loss of life, with a death toll of about 20 million.  A string of civil disturbances followed, including the Punti–Hakka Clan Wars, Nian Rebellion, Dungan Revolt, and Panthay Rebellion.  All rebellions were ultimately put down, but at enormous cost and with millions dead, seriously weakening the central imperial authority. China never rebuilt a strong central army, and many local officials used their military power to effectively rule independently in their provinces. 
Yet the dynasty appeared to recover in the Tongzhi Restoration (1860-1872), led by Manchu royal family reformers and Han Chinese officials such as Zeng Guofan and his proteges Li Hongzhang and Zuo Zongtang. Their Self-Strengthening Movement made effective institutional reforms, imported Western factories and communications technology, with prime emphasis on strengthening the military. However, the reform was undermined by official rivalries, cynicism, and quarrels within the imperial family. The defeat of Yuan Shikai's modernized " Beiyang Fleet" in the First Sino-Japanese War (1894–1895) led to the formation of the New Army. The Guangxu Emperor, advised by Kang Youwei, then launched a comprehensive reform effort, the Hundred Days' Reform (1898). Empress Dowager Cixi, however, feared that precipitous change would lead to bureaucratic opposition and foreign intervention and quickly suppressed it.
In the summer of 1900, the Boxer Uprising opposed foreign influence and murdered Chinese Christians and foreign missionaries. When Boxers entered Beijing, the Qing government ordered all foreigners to leave, but they and many Chinese Christians were besieged in the foreign legations quarter. An Eight-Nation Alliance sent the Seymour Expedition of Japanese, Russian, British, Italian, German, French, American, and Austrian troops to relieve the siege, but they were forced to retreat by Boxer and Qing troops at the Battle of Langfang. After the Alliance's attack on the Dagu Forts, the court declared war on the Alliance and authorized the Boxers to join with imperial armies. After fierce fighting at Tientsin, the Alliance formed the second, much larger Gaselee Expedition and finally reached Beijing; the Empress Dowager evacuated to Xi'an. The Boxer Protocol ended the war, exacting a tremendous indemnity.
The Qing court then instituted " New Policies" of administrative and legal reform, including abolition of the examination system. But young officials, military officers, and students debated reform, perhaps a constitutional monarchy, or the overthrow of the dynasty and the creation of a republic. They were inspired by an emerging public opinion formed by intellectuals such as Liang Qichao and the revolutionary ideas of Sun Yat-sen. A localised military uprising, the Wuchang Uprising, began on 10 October 1911, in Wuchang (Today part of Wuhan), and soon spread. The Republic of China was proclaimed on 1 January 1912, ending 2,000 years of dynastic rule.
Republic of China (since 1912)
The provisional government of the Republic of China was formed in Nanking on 12 March 1912. Sun Yat-sen became President of the Republic of China, but he turned power over to Yuan Shikai, who commanded the New Army. Over the next few years, Yuan proceeded to abolish the national and provincial assemblies and declared himself as the emperor of Empire of China in late 1915. Yuan's imperial ambitions were fiercely opposed by his subordinates; faced with the prospect of rebellion, he abdicated in March 1916 and died of natural causes in June.
Yuan's death in 1916 left a power vacuum; the republican government was all but shattered. This opened the way for the Warlord Era, during which much of China was ruled by shifting coalitions of competing provincial military leaders and the Beiyang government. Intellectuals, disappointed in the failure of the Republic, launched the New Culture Movement.
In 1919, the May Fourth Movement began as a response to the pro-Japanese terms imposed on China by the Treaty of Versailles following World War I. It quickly became a nationwide protest movement. The protests were a moral success as the cabinet fell and China refused to sign the Treaty of Versailles, which had awarded German holdings of Shandong to Japan. Political and intellectual ferment waxed strong throughout the 1920s and 1930s. According to Patricia Ebrey:
- "Nationalism, patriotism, progress, science, democracy, and freedom were the goals; imperialism, feudalism, warlordism, autocracy, patriarchy, and blind adherence to tradition were the enemies. Intellectuals struggled with how to be strong and modern and yet Chinese, how to preserve China as a political entity in the world of competing nations." 
In the 1920s, Sun Yat-sen established a revolutionary base in Guangzhou and set out to unite the fragmented nation. He welcomed assistance from the Soviet Union (itself fresh from Lenin's takeover), he entered into an alliance with the fledgeling Communist Party of China. After Sun's death from cancer in 1925, one of his protégés, Chiang Kai-shek, seized control of the Nationalist Party (KMT) and succeeded in bringing most of south and central China under its rule in the Northern Expedition (1926–1927). Having defeated the warlords in the south and central China by military force, Chiang was able to secure the nominal allegiance of the warlords in the North and establish the Nationalist government in Nanking. In 1927, Chiang turned on the CPC and relentlessly chased the CPC armies in NRA and its leaders out of KMT. In 1934, driven from their mountain bases such as the Chinese Soviet Republic, the CPC forces embarked on the Long March across China's most desolate terrain to the northwest, where they established a guerrilla base at Yan'an in Shaanxi Province. During the Long March, the communists reorganized under a new leader, Mao Zedong (Mao Tse-tung).
The bitter Chinese Civil War between the Nationalists and the Communists continued, openly or clandestinely, through the 14-year-long Japanese occupation of various parts of the country (1931–1945). The two Chinese parties nominally formed a United Front to oppose the Japanese in 1937, during the Second Sino-Japanese War (1937–1945), which became a part of World War II. Japanese forces committed numerous war atrocities against the civilian population, including biological warfare (see Unit 731) and the Three Alls Policy (Sankō Sakusen), the three alls being: "Kill All, Burn All and Loot All". 
Following the defeat of Japan in 1945, the war between the Nationalist government forces and the CPC resumed, after failed attempts at reconciliation and a negotiated settlement. By 1949, the CPC had established control over most of the country. Odd Arne Westad says the Communists won the Civil War because they made fewer military mistakes than Chiang, and because in his search for a powerful centralized government, Chiang antagonized too many interest groups in China. Furthermore, his party was weakened in the war against the Japanese. Meanwhile, the Communists told different groups, such as peasants, exactly what they wanted to hear, and cloaked themselves in the cover of Chinese Nationalism.  During the civil war both the Nationalists and Communists carried out mass atrocities, with millions of non-combatants killed by both sides.  These included deaths from forced conscription and massacres.  When the Nationalist government forces were defeated by CPC forces in mainland China in 1949, the Nationalist government retreated to Taiwan with its forces, along with Chiang and a large number of their supporters; the Nationalist government had taken effective control of Taiwan at the end of WWII as part of the overall Japanese surrender, when Japanese troops in Taiwan surrendered to the Republic of China troops. 
Until the early 1970s, the ROC was recognized as the sole legitimate government of China by the United Nations, the United States and most Western nations, refusing to recognize the PRC on account of the Cold War. This changed in 1971 when the PRC was seated in the United Nations, replacing the ROC. The KMT ruled Taiwan under martial law until 1987, with the stated goal of being vigilant against Communist infiltration and preparing to retake mainland China. Therefore, political dissent was not tolerated during that period.
In the 1990s, the ROC underwent a major democratic reform, beginning with the 1991 resignation of the members of the Legislative Yuan and National Assembly elected in 1947. These groups were originally created to represent mainland China constituencies. Also lifted were the restrictions on the use of Taiwanese languages in the broadcast media and in schools. This culminated with the first direct presidential election in 1996 against the Democratic Progressive Party (DPP) candidate and former dissident, Peng Min-ming. In 2000, the KMT status as the ruling party ended when the DPP took power, only to regain its status in the 2008 election by Ma Ying-jeou.
People's Republic of China (since 1949)
Major combat in the Chinese Civil War ended in 1949 with Kuomintang (KMT) pulling out of the mainland, with the government relocating to Taipei and maintaining control only over a few islands. The Communist Party of China was left in control of mainland China. On 1 October 1949, Mao Zedong proclaimed the People's Republic of China.  "Communist China" and "Red China" were two common names for the PRC. 
The PRC was shaped by a series of campaigns and five-year plans. The economic and social plan known as the Great Leap Forward caused an estimated 45 million deaths.  Mao's government carried out mass executions of landowners, instituted collectivisation and implemented the Laogai camp system. Execution, deaths from forced labor and other atrocities resulted in millions of deaths under Mao. In 1966 Mao and his allies launched the Cultural Revolution, which continued until Mao's death a decade later. The Cultural Revolution, motivated by power struggles within the Party and a fear of the Soviet Union, led to a major upheaval in Chinese society.
In 1972, at the peak of the Sino-Soviet split, Mao and Zhou Enlai met US president Richard Nixon in Beijing to establish relations with the United States. In the same year, the PRC was admitted to the United Nations in place of the Republic of China, with permanent membership of the Security Council.
A power struggle followed Mao's death in 1976. The Gang of Four were arrested and blamed for the excesses of the Cultural Revolution, marking the end of a turbulent political era in China. Deng Xiaoping outmaneuvered Mao's anointed successor chairman Hua Guofeng, and gradually emerged as the de facto leader over the next few years.
Deng Xiaoping was the Paramount Leader of China from 1978 to 1992, although he never became the head of the party or state, and his influence within the Party led the country to significant economic reforms. The Communist Party subsequently loosened governmental control over citizens' personal lives and the communes were disbanded with many peasants receiving multiple land leases, which greatly increased incentives and agricultural production. In addition, there were many free market areas opened. The most successful free market areas was Shenzhen. It is located in Guangdong and the property tax free area still exists today. This turn of events marked China's transition from a planned economy to a mixed economy with an increasingly open market environment, a system termed by some  as " market socialism", and officially by the Communist Party of China as " Socialism with Chinese characteristics". The PRC adopted its current constitution on 4 December 1982.
In 1989 the death of former general secretary Hu Yaobang helped to spark the Tiananmen Square protests of that year, during which students and others campaigned for several months, speaking out against corruption and in favour of greater political reform, including democratic rights and freedom of speech. However, they were eventually put down on 4 June when PLA troops and vehicles entered and forcibly cleared the square, with many fatalities. This event was widely reported, and brought worldwide condemnation and sanctions against the government.   A filmed incident involving the " tank man" was seen worldwide.
CPC general secretary and PRC President Jiang Zemin and PRC Premier Zhu Rongji, both former mayors of Shanghai, led post-Tiananmen PRC in the 1990s. Under Jiang and Zhu's ten years of administration, the PRC's economic performance pulled an estimated 150 million peasants out of poverty and sustained an average annual gross domestic product growth rate of 11.2%.   The country formally joined the World Trade Organization in 2001. By 1997 and 1999, former European colonies of Hong Kong and Macau became special administrative regions of China.
Although the PRC needs economic growth to spur its development, the government began to worry that rapid economic growth was degrading the country's resources and environment. Another concern is that certain sectors of society are not sufficiently benefiting from the PRC's economic development; one example of this is the wide gap between urban and rural areas. As a result, under former CPC general secretary and President Hu Jintao and Premier Wen Jiabao, the PRC initiated policies to address issues of equitable distribution of resources, but the outcome was not known as of 2014 [update].  More than 40 million farmers were displaced from their land,  usually for economic development, contributing to 87,000 demonstrations and riots across China in 2005.  For much of the PRC's population, living standards improved very substantially and freedom increased, but political controls remained tight and rural areas poor.
