Treaty of Córdoba Grants Mexican Independence

Summary

After eleven years of fighting in the Mexican War of Independence, royalist and insurgent forces reached a political settlement. Agustín de Iturbide, leader of the Army of the Three Guarantees, negotiated with incoming Spanish Viceroy Juan O'Donojú in Córdoba, Veracruz. On August 24, 1821, they signed the Treaty of Córdoba, which recognized Mexico as an independent constitutional monarchy under the Plan of Iguala. The agreement provided for a Mexican empire, religious unity, and social equality among classes. Although Spain later repudiated the treaty, it effectively ended Spanish rule on the ground.

Why It Matters

The treaty formalized Mexico's separation from Spain and shaped its early political structure as a monarchy before becoming a republic. It influenced independence movements elsewhere in Latin America and established key principles that guided Mexican governance.
