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.^[5]

It had two capitals: first Saltillo (1822–1825) for petition^{[clarification needed]} 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 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.

The state remained in existence until the adoption of the 1835 "Constitutional Bases", whereby the federal republic was converted into a unitary one, and the nation's states (estados) were turned into departments (departamentos). The State of Coahuila and Texas was split in two and became the Department of Coahuila and the Department of Texas.

Both Coahuila and Texas seceded from Mexico because Antonio López de Santa Anna attempted to collect taxes, end slavery, and centralize the government, and groups of rebels, led primarily by immigrants and slave-owners, were unwilling to obey the laws of the rest of Mexico. Texas eventually became the independent Republic of Texas, which in 1845 became a state of the United States of America. Coahuila joined with Nuevo León and Tamaulipas, to form the short-lived Republic of the Rio Grande.
