Saltillo in the context of "Universidad La Salle"

Coahuila, formally Coahuila de Zaragoza, officially the Free and Sovereign State of Coahuila de Zaragoza, is one of the 31 states of Mexico. The largest city and state capital is the city of Saltillo; the second largest is Torreón and the third largest is Monclova (a former state capital); the fourth largest is Piedras Negras; and the fifth largest is Ciudad Acuña.

Coahuila borders the Mexican states of Nuevo León to the east, Zacatecas to the south, and Durango and Chihuahua to the west. To the north, Coahuila accounts for a 512 kilometres (318 mi) stretch of the Mexico–United States border, adjacent to the U.S. state of Texas along the course of the Rio Grande (Río Bravo del Norte). With an area of 151,563 square kilometres (58,519 sq mi), it is the nation's third-largest state. It comprises 38 municipalities (municipios). In the 2020 Census, Coahuila had a population of 3,146,771.

Coahuila y Tejas, officially the Estado Libre y Soberano de Coahuila y Tejas (lit. 'Free and Sovereign State of Coahuila and Texas'), was one of the constituent states of the newly established United Mexican States under its 1824 Constitution.

It had two capitals: first Saltillo (1822–1825) for petition of Miguel Ramos Arizpe, that changing the capital for dispute of political groups, but Monclova recovered primacy because it was the colonial capital since 1689; this action provoked a struggle between the residents of Saltillo and Monclova in 1838–1840, but the political actions of Antonio López de Santa Anna convinced the monclovitas to accept the final change of political powers to Saltillo. In the case of Tejas its territory was organized for administrative purposes, with the state being divided into three districts: Béxar, comprising the area covered by Texas; Monclova, comprising northern Coahuila; and Río Grande Saltillo, comprising southern Coahuila.

Monclova (Spanish pronunciation: [moŋˈkloβa]), is a city and the seat of the surrounding municipality of the same name in the northern Mexican state of Coahuila. According to the 2015 census, the city had 231,107 inhabitants. Its metropolitan area has 381,432 inhabitants and a population density of 29.88 inhabitants per square kilometer. Monclova is the third-largest city and metropolitan area in the state in terms of population, after Torreón and Saltillo.

The city accounts for the highest production of steel in Mexico as well as Latin America, hence its nickname "The Steel Capital".

The serape, sarape or jorongo is a long blanket-like shawl or cloak, often brightly colored and fringed at the ends, worn in Mexico, especially by men. The spelling of the word sarape (or zarape) is the accepted form in Mexico and other Spanish-speaking countries. The term serape is for the rectangular woven blanket (no openings), though in more recent years it can also be used to refer to a very soft rectangular blanket with an opening in the middle for one's head, similar to a poncho, called gabán, or jorongo in Mexico. Modern variations of some serapes are made with matching hoods for head covering. The length varies, but front and back normally reach knee length on an average person.

Available in various colors and design patterns, the typical colors of serapes from the highland regions are two-tone combinations of black, grey, brown, or tan depending on the natural color of the sheep flocks grown in the area, with large design patterns utilizing traditional indigenous motifs. On the other hand, the traditional serape as made in the Mexican state of Coahuila in north-eastern Mexico near the city of Saltillo often consists of a dark base color with bands of yellow, orange, red, blue, green, purple, or other bright colors. The ends are usually fringed.

The Regional Confederation of Mexican Workers (Spanish: Confederación Regional Obrera Mexicana, CROM) is a federation of labor unions in Mexico, whose power was at its height between 1918 and 1928. CROM was an umbrella organization for both industrial workers as well as agricultural workers and peasants. Industrial unions of railway workers, petroleum workers, and textile workers were strong enough on their own that they could function without CROM's support.

It was founded in Saltillo in 1918 at a congress of labor delegates called by Mexican President Venustiano Carranza. The federation, of which Luis Napoleón Morones Negrete was a major leader, marked a departure from the traditionally-anarchist stance of Mexican labor to a nationalist position.
