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.
Convention of 1833
Mexico won its independence from Spain in 1821. After the new country's monarchy was overthrown, the Constitution of 1824 established a federalist republic composed of multiple states. Sparsely populated provinces were denied independent statehood and instead merged with neighboring areas. Mexican Texas, which marked the country's eastern border with the United States, was combined with Coahuila to form the new state Coahuila y Tejas. To facilitate government of the large area, the state was subdivided into several departments; all of Texas was included in the Department of Béxar.
