Chihuahua is a state in northern Mexico with a mainland area of , slightly bigger than the United Kingdom. It is surrounded by the Mexican states of Sonora to the west, Sinaloa to the south-west, Durango to the south, and Coahuila to the east, and by the U.S. states of Texas to the north-east and New Mexico to the north. Chihuahua is the largest state in Mexico by area, and therefore has the nickname "El Estado Grande."
Although Chihuahua is primarily identified with its namesake, the Chihuahuan Desert, it has more forests than any other state. On the slope of the Sierra Madre Occidental mountains (around the regions of Casas Grandes, Cuauhtémoc and Parral), there are vast prairies of short yellow grass, the source of the bulk of the state's agricultural production.
As of 2005, there were 3.2 million inhabitants of the state. The largest city is the U.S.-border city of Ciudad Juárez, which has 1,301,452 residents (2005 census). The capital, Chihuahua, has 748,518 inhabitants.
The state also has a large service sector: tourism, banking and high-tech enterprises.
One of the most notable features of Chihuahua is the Barranca del Cobre, or Copper Canyon, a spectacular canyon system larger and deeper than the Grand Canyon.
Chihuahua played a pivotal role in the Mexican Revolution and was a battleground between revolutionary forces led by Pancho Villa and federal forces.
Chihuahua is one of the Mexican states that holds a slight population plurality of people that are primarily of European ancestry (as is the case in much of northern Mexico), with around 49% of the state population being of European descent, commonly Spanish, Italian, German, French, Irish, Russian and Dutch. Around 45% of its population has mixed European and Amerindian ancestry (Mestizo). The population of Amerindians in northern Mexico tends to be low compared to the southern part, and Chihuahua is no exception. While there are Amerindians in Chihuahua, they comprise only around 6% of the state's population, and they mostly live in isolated areas in the mountains.
Nueva Vizcaya was the first province of northern New Spain to be explored and settled by the Spanish. In 1823, after the Mexican War of Independence, the province was divided into two states, Chihuahua and Durango.
Because of the general instability of the federal government during 1828, the installation of the new legislature did not take place until the middle of the following year. It was quickly dissolved by Governor Baca, who replaced it with a more pronounced Yorkino type. When Guerrero’s liberal administration was overthrown in December, Gaspar de Ochoa aligned with Anastasio Bustamante, and in February 1830, organized an opposition group that arrested the new governor, F. Elorriaga, along with other prominent Yorkinos. He then summoned the legislature, which had been dissolved by Baca. The civil and military authorities were now headed by J. A. Pescador and Ochoa.
Comandante general Simón Elías González, was nominated governor and military command was given to Colonel J.J. Calvo, whose firmness had earned well-merited praise. The state was in the midst of a war with the Apaches, which became the focus of all their energy and resources. After a review of the situation, Simón Elías González declared that the interests of the territory would be best served by uniting the civil and military power, at least while the campaign lasted. He resigned under opposition, but was renominated in 1837.
The state's major communities include:
