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 seventeen articles, which developed the proposals of the Plan of Iguala. The Treaty of Córdoba is the first document in which Spanish and Mexican officials accept the liberty of what will become the First Mexican Empire, although 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.
