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.
Centralist Republic of Mexico
Months later, Antonio López de Santa Anna, in response to the declaration of independence, threatened to send in the troops if it was not reversed while also assuring the Tabasco authorities that Federalism would soon be reinstated. This combined threat and promise culminated in the reinstatement of Tabasco into the Mexican Republic on December 2, 1842. But four years later, Tabasco again declared its independence in November 1846 as a protest to the lack of Central government assistance in resisting the American occupation of its coast earlier that same year.
