American Century Information
|United States of America|
The American Century   is a characterization of the period since the middle of the 20th century as being largely dominated by the United States in political, economic, and cultural terms. It is comparable to the description of the period 1815–1914 as Britain's Imperial Century.  The United States' influence grew throughout the 20th century, but became especially dominant after the end of World War II, when only two superpowers remained, the United States and the Soviet Union. After the dissolution of the Soviet Union in 1991, the United States remained the world's only superpower,  and became the hegemon, or what some have termed a hyperpower. 
The term was coined by Time publisher Henry Luce to describe what he thought the role of the United States would be and should be during the 20th century.  Luce, the son of a missionary, in a February 17, 1941 Life magazine editorial  urged the United States to forsake isolationism for a missionary's role, acting as the world's Good Samaritan and spreading democracy. He called upon the US to enter World War II to defend democratic values:
Throughout the 17th century and the 18th century and the 19th century, this continent teemed with manifold projects and magnificent purposes. Above them all and weaving them all together into the most exciting flag of all the world and of all history was the triumphal purpose of freedom.
It is in this spirit that all of us are called, each to his own measure of capacity, and each in the widest horizon of his vision, to create the first great American Century. 
Democracy and other American ideals would "do their mysterious work of lifting the life of mankind from the level of the beasts to what the Psalmist called a little lower than the angels". Only under the American Century can the world "come to life in any nobility of health and vigor". 
According to David Harvey, Luce believed "the power conferred was global and universal rather than territorially specific, so Luce preferred to talk of an American century rather than an empire".  In the same article he called upon United States "to exert upon the world the full impact of our influence, for such purposes as we see fit and by such means as we see fit". 
Beginning at the end of the 19th century, with the Spanish–American War in 1898 and the Boxer Rebellion, the United States began to play a more prominent role in the world beyond the North American continent. The government adopted protectionism after the Spanish–American War to develop its native industry and built up the navy, the " Great White Fleet". When Theodore Roosevelt became president in 1901, he accelerated a foreign policy shift away from isolationism and towards foreign involvement, a process which had begun under his predecessor William McKinley.
For instance, the United States fought the Philippine–American War against the First Philippine Republic to solidify its control over the newly acquired Philippines.  In 1904, Roosevelt committed the United States to building the Panama Canal, creating the Panama Canal Zone. Interventionism found its formal articulation in the 1904 Roosevelt Corollary to the Monroe Doctrine, proclaiming a right for the United States to intervene anywhere in the Americas, a moment that underlined the emergent US regional hegemony.
After the outbreak of World War I in 1914, the United States pursued a policy of non-intervention, avoiding conflict while trying to broker a peace. President Woodrow Wilson later argued that the war was so important that the US had to have a voice in the peace conference.  The United States was never formally a member of the Allies but entered the war in 1917 as a self-styled "Associated Power". Initially the United States had a small army, but, after the passage of the Selective Service Act, it drafted 2.8 million men,  and, by summer 1918, was sending 10,000 fresh soldiers to France every day. The war ended in 1919 with the Treaty of Versailles. The United States then adopted a policy of isolationism, having refused to endorse the 1919 Versailles Treaty or formally enter the League of Nations. 
During the interwar period, economic protectionism took hold in the United States, particularly as a result of the Smoot–Hawley Tariff Act which is credited by economists with the prolonging and worldwide propagation of the Great Depression. :33 From 1934, trade liberalization began to take place through the Reciprocal Trade Agreements Act.
With the onset of World War II in 1939, Congress loosened the Neutrality Acts of 1930s but remained opposed to entering the European war.  In 1940, the United States ranked 18th in terms of military power.    The Neutrality Patrol had US destroyers fighting at sea, but no state of war had been declared by Congress. American public opinion remained isolationist. The 800,000-member America First Committee vehemently opposed any American intervention in the European conflict, even as the US sold military aid to the United Kingdom and the Soviet Union through the Lend-Lease program.
In the 1941 State of the Union address, known as the Four Freedoms speech, President Franklin D. Roosevelt made a break with the tradition of non-interventionism. He outlined the US role in helping allies already engaged in warfare. By August, President Roosevelt and British Prime Minister Winston Churchill had drafted the Atlantic Charter to define goals for the post-war world.  In December 1941, Japan attacked American and British holdings with near-simultaneous offensives against Southeast Asia and the Central Pacific including an attack on the US fleet at Pearl Harbor.  These attacks led the United States and United Kingdom to declare war on Japan. Three days later, Germany and Italy declared war on the United States, which the United States reciprocated. 
In an effort to maintain peace after World War II,  the Allies formed the United Nations, which came into existence on October 24, 1945,  and adopted the Universal Declaration of Human Rights in 1948, as a common standard for all member states.  The U.S. worked closely with the United Kingdom to establish the IMF, World Bank and NATO.  
Pax Americana represents the relative peace in the Western world, resulting in part from the preponderance of power enjoyed by the United States of America starting around the middle of the 20th century. Although the term finds its primary utility in the late 20th century, it has been used in other times in the 20th century. Its modern connotations concern the peace established after the end of World War II in 1945.
The American Century existed through the Cold War and demonstrated the status of the United States as the foremost of the world's two superpowers. After the Cold War, the most common belief held that only the United States fulfilled the criteria to be considered a superpower.  Its geographic area composed the fourth-largest state in the world, with an area of approximately 9.37 million km2.  The population of the US was 248.7 million in 1990, at that time the third-largest nation. 
In the mid-to-late 20th century, the political status of the US was defined as a strongly capitalist federation and constitutional republic. It had a permanent seat on the United Nations Security Council plus two allies with permanent seats, the United Kingdom and France. The US had strong ties with capitalist Western Europe, Latin America, British Commonwealth, and several East Asian countries ( Korea, Taiwan, Japan). It allied itself with both right-wing dictatorships and capitalist democracies. 
The American Century includes the political influence of the United States but also its economic influence. Many states around the world would, over the course of the 20th century, adopt the economic policies of the Washington Consensus, sometimes against the wishes of their populations. The economic force of the US was powerful at the end of the century due to it being by far the largest economy in the world. The US had large resources of minerals, energy resources, metals, and timber, a large and modernized farming industry and large industrial base. The United States dollar is the dominant world reserve currency under the Bretton Woods system. US systems were rooted in capitalist economic theory based on supply and demand, that is, production determined by customers' demands. America was allied with the G7 major economies. US economic policy prescriptions were the "standard" reform packages promoted for crisis-wracked developing countries by Washington, DC-based international institutions such as the International Monetary Fund (IMF), World Bank, as well as the US Treasury Department. 
The military of the United States was a naval-based advanced military with by far the highest military expenditure in the world.  The United States Navy was the world's largest navy, with the largest number of aircraft carriers, bases all over the world (particularly in an incomplete "ring" bordering the Warsaw Pact states to the west, south and east). The US had the largest nuclear arsenal in the world during the first half of the Cold War, one of the largest armies in the world and one of the two largest air forces in the world. Its powerful military allies in Western Europe (the North Atlantic Treaty Organisation states) had their own nuclear capabilities. The US also possessed a powerful global intelligence network in the Central Intelligence Agency.
The cultural impact of the US, often known as Americanization, is seen in the influence on other countries of US music, TV, films, art, and fashion, as well as the desire for freedom of speech and other guaranteed rights its residents enjoy. US pop stars such as Elvis Presley, Michael Jackson, and Madonna have become global celebrities. 
Critics have condemned Luce's " jingoistic missionary zeal".  Others have noted the end of the 20th century and the American Century, most famously the late gonzo journalist Hunter S. Thompson who titled his autobiography Kingdom of Fear: Loathsome Secrets of a Star Crossed Child in the Last Days of the American Century.
With the advent of the new millennium, critics from the University of Illinois stated that it was a matter of debate whether America was losing its superpower status, especially in relation to China's rise.  Other analysts have made the case for the "American Century" fitting neatly between America's late entry into World War I in 1917 and the inauguration of its 45th President in 2017.
