The name Coahuila derives from native terms for the region, and has been known by variations such as Cuagüila and Cuauila. Some historians believe that this means “flying serpent”, “place of many trees”, or “place where serpents creep”. The official name of the state is Coahuila de Zaragoza, in honor of General Ignacio Zaragoza.
The Spanish explored the north of Mexico some decades after their victory in Tenochtitlan, the capital of the Aztecs. Such exploration was delayed because the northern climate was harsher and there was no gold. The first Spanish settlement in the region now called Coahuila was at Minas de la Trinidad in 1577. Saltillo was settled in 1586, to form part of the province of Nueva Vizcaya of the Vice-royalty of New Spain. Later it became one of the first provinces of Nueva Extremadura to be explored by Europeans.
"Coahuila and Texas" was one of the constituent states of the newly independent United Mexican States under their 1824 Constitution, and included Texas, Coahuila and Nuevo León. Later in the same year Nuevo León was detached, but Texas remained a part of the state until 1836, when it seceded to form the Republic of Texas. Monclova was the capital of the state from 1833 to 1835.
In 1840 Coahuila briefly became a member of the short lived Republic of the Rio Grande.
On April 4, 2004, the border city of Piedras Negras was flooded. More than 30 people died and more than 4,000 lost their homes. In 2007 Coahuila became the first state in Mexico to offer civil unions (Pacto Civil de Solidaridad) to same-sex couples. 
The Sierra Madre Oriental runs northwest to southeast through the State, and the higher elevations are home to the Sierra Madre Oriental pine-oak forests. The northernmost fingers of the Sierra Madre Oriental, the Sierra del Burro and the Sierra del Carmen, reach to the border with the United States at the Rio Grande.
East of the range, the land slopes gently toward the Rio Grande, and is drained by several rivers, including the Salado and its tributary, the Sabinas River. The Tamaulipan mezquital, a dry shrubland ecoregion, occupies the eastern portion of the State, and extends across the Rio Grande into southern Texas.
The portion of the State west of the Sierra Madre Oriental lies on the Mexican Plateau, and is part of the Chihuahuan Desert. The Bolsón de Mapimí is a large endorheic basin which covers much of the western portion of the State and extends into adjacent portions of Chihuahua, Durango, and Zacatecas. The Nazas River, which flows east from Durango, and the Aguanaval River, which flows north from Zacatecas, empty into lakes in the Bolsón. Torreón, the most populous city in the State, lies on the Nazas in the irrigated Laguna Region, the (Comarca Lagunera), which straddles the border of Coahuila and Durango.
Coahuila contains two biosphere reserves. Maderas del Carmen lies on the northern border of the State, and includes sections of the Chihuahuan desert and sky islands of pine-oak forest in the Sierra del Carmen. The springs, lakes, and wetlands of Cuatro Ciénegas lie west of Monclova on the west slope of the Sierra Madre.
Coahuila is largely arid or semi-arid, but the rivers of the State support extensive irrigated agriculture, particularly cotton. The Parras district in the southern part of the State produces wines and brandies. The pine-oak forests of the Sierra Madre produce timber.
The last population census run across Mexico in the year 2015, reports Coahuila de Zaragoza as having 2,954,915 inhabitants, which, considering its size, means that the state has a very low density, in fact as low as only 15 persons per square kilometer.
Coahuila's population is mainly made up of Criollos along with Mestizos. Less than 7,500 natives reside in Coahuila, or merely 0.3% of the total population. The rest of the population is composed of Americans, Canadian, and Japanese communities.
The rest of the demographic particulars in the state are very similar to national averages, such as a high life expectancy (reaching 75 years of age) and a Catholic majority.
Basic public education in Coahuila is mainly managed by the state's Secretary of Education, but federal-sustained schools are also very common. There are also a lot of private schools in the main cities of the state.
Some of the most recognized universities in Coahuila include:
Iberoamerican University (Universidad Iberoamericana)
A private university part of the Jesuit University System with a campus in Torreón and a university extension center in Saltillo.
The most recognized public technological university of La Laguna Region located in the city of Torreón.
It is the most known technological university in Mexico with two campuses: one in Saltillo and another one in Torreón.

About 95% of Mexico's coal reserves are found in Coahuila, which is the country's top mining state.
Torreón has Met-Mex Peñoles, a mining company. The city is the world's largest silver producer and Mexico's largest gold producer. It also has Lala, a dairy products company, which produces 40% of Mexico's milk consumption.
As of 2005, Coahuila's economy represents 3.5% of Mexico's total gross domestic product or US$22,874 million.  Coahuila's economy has a strong focus on export oriented manufacturing (i.e. maquiladora / INMEX). As of 2005, 221,273 people are employed in the manufacturing sector.  Foreign direct investment in Coahuila was US$143.1 million for 2005. The average wage for an employee in Coahuila is approximately 190 pesos per day.[ citation needed]
On the other hand, Coahuila is the Mexican state with the highest level of public debt in the nation.
