Treaty of Córdoba
The Treaty of Córdoba established Mexican independence from Spain at the conclusion of the Mexican War of Independence. It was signed on August 24, 1821 in Córdoba, Veracruz, Mexico. The signatories were the head of the Army of the Three Guarantees, Agustín de Iturbide, and, acting on behalf of the Spanish government, "Jefe Político Superior" Juan O'Donojú. The treaty has 17 articles, which developed the proposals of the Plan of Iguala. The Treaty is the first document in which Spanish (without authorization) and Mexican officials accept the liberty of what will become the First Mexican Empire, but it is not today recognized as the foundational moment, since these ideas are often attributed to the Grito de Dolores (September 16, 1810). The treaty was rejected by the Spanish government. Spain did not recognize Mexico's independence until December 1836.
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.
