The Declaration of Independence of the Mexican Empire is publicly proclaimed.

The Declaration of Independence of the Mexican Empire, marked the official conclusion of Mexico’s long struggle for independence from Spanish colonial rule. Following over a decade of war beginning in 1810 with Miguel Hidalgo’s “Grito de Dolores,” the declaration represented not just a political break but the birth of a new sovereign state. The document was crafted by the Provisional Governmental Junta, a body formed after the successful Treaty of Córdoba, which formalized Mexico’s independence under the Plan of Iguala—a plan that sought to create a constitutional monarchy with equality between Spaniards and Creoles.

The declaration itself was a concise yet powerful affirmation of Mexico’s right to self-governance. It proclaimed the Mexican nation as “sovereign and independent,” freed from all political and religious ties to Spain or any other foreign power. This assertion mirrored the Enlightenment ideals and global independence movements of the late 18th and early 19th centuries, drawing inspiration from earlier declarations like those of the United States (1776) and Haiti (1804). However, unlike the U.S. document, the Mexican declaration emphasized unity under the Catholic faith and the creation of an empire, highlighting the conservative and monarchical tendencies that shaped the early Mexican state.

In the immediate aftermath, the declaration set the stage for the short-lived First Mexican Empire under Emperor Agustín de Iturbide. Though the empire quickly dissolved by 1823 due to internal divisions and financial strain, the declaration’s importance endured. It was the foundational act of national sovereignty, symbolizing Mexico’s emergence as a distinct political entity in the Americas. It established not only independence but also the ideological framework for Mexico’s early nation-building efforts—an intricate balance between liberal aspirations and conservative traditions that would continue to define its political evolution throughout the 19th century.
