Mexican War of Independence
The Mexican War of Independence () was an armed conflict, and the culmination of a political and social process which ended the rule of Spain in 1821 in the territory of New Spain. The war had its antecedent in Napoleon's French invasion of Spain in 1808; it extended from the Cry of Dolores by Father Miguel Hidalgo y Costilla on September 16, 1810, to the entrance of the Army of the Three Guarantees led by Agustín de Iturbide to Mexico City on September 27, 1821. September 16 is celebrated as Mexican Independence Day.
Mexican Texas
Mexican Texas is the historiographical name used to refer to the era of Texan history between 1821 and 1836, when it was part of Mexico. Mexico gained independence from Spain in 1821 after winning its war. Initially, Mexican Texas operated similarly to Spanish Texas. Ratification of the 1824 Constitution of Mexico created a federal structure, and the province of Tejas was joined with the province of Coahuila to form the state of Coahuila y Tejas.
