Solemn Act of the Declaration of Independence of Northern America was the formal proclamation that ratified independence for the territories of New Spain in late 1821, consolidating the political outcomes of the Mexican War of Independence and the Plan of Iguala. The Act represented a legal and symbolic break from the Spanish Empire and underpinned the short-lived First Mexican Empire, setting the stage for subsequent constitutional and military conflicts involving figures such as Agustín de Iturbide and Vicente Guerrero. Its text and adoption intersected with diplomatic recognition efforts involving the United Kingdom, the United States, and the restored Spanish monarchy under Ferdinand VII.

Background and Causes

The Act emerged from the closing phases of the Mexican War of Independence (1810–1821), in which leaders including Miguel Hidalgo y Costilla, José María Morelos, Vicente Guerrero, and royalist-turned-independence general Agustín de Iturbide played decisive roles. Military reversals for the Spanish Empire in the Americas, fiscal strains from the Peninsular War, and political currents from the Spanish Constitution of 1812 and the Liberal Triennium contributed to imperial instability. The 1820 pronunciamiento of Rafael del Riego and related developments in Spain revived constitutional debates that alienated conservative creoles and royal officials in New Spain, prompting the negotiation of the Plan of Iguala and the subsequent Treaty of Córdoba between Iturbide and the last captain general, Juan O'Donojú.

Drafting and Adoption

Drafting followed the military and political pact embodied in the Plan of Iguala, which proposed a constitutional monarchy, Catholic unity, and unity of peninsulares and criollos. The Pact of Iguala's leaders, including Agustín de Iturbide and Vicente Guerrero, convened political assemblies in Mexico City and allied provinces to formalize independence through a solemn declaratory instrument. The Treaty of Córdoba, negotiated with Juan O'Donojú, provided a framework that Spanish authorities in New Spain accepted as de facto separation; the Solemn Act was adopted on 28 November 1821 by a constituent junta comprised of military, clerical, and civic elites influenced by figures such as Bishop Juan de Dosal and prominent hacendados. The ceremonial proclamation drew attendance from representatives of provinces including Puebla, Veracruz, Guadalajara, Michoacán, and Yucatán.

Content and Legal Provisions

The Act proclaimed the political independence of the territories formerly under Viceroyalty of New Spain authority and asserted succession protocols aligned with the Plan of Iguala's intent to offer the crown to a European monarch or establish a Mexican sovereign if no European accepted. It referenced Hispanic legal traditions and canonical legitimacy by invoking Roman Catholic Church authority and appealed to precedents from the United States Declaration of Independence and contemporary Latin American pronouncements like the Acta de Independencia del Perú. Provisions addressed the continuity of obligations, property rights of peninsulares and criollos, military pensions for veterans of the insurgency, and the legal standing of municipal ayuntamientos such as those in Mexico City and Querétaro. The text served more as a declaratory and legitimizing instrument than as a comprehensive constitution, delegating detailed governance arrangements to subsequent acts that led to the proclamation of Agustín de Iturbide as emperor and later to the drafting of the Constitution of 1824.

Immediate Aftermath and Recognition

Following the Act's proclamation, Iturbide's proclamation as Emperor of the Mexican Empire in May 1822 and the political consolidation under the First Mexican Empire provoked regional tensions with provincial authorities in Texas, Alta California, and Yucatán. International recognition proceeded cautiously: the United Kingdom and the United States engaged in pragmatic commercial and diplomatic overtures, while the restored Spanish monarchy under Ferdinand VII initially refused recognition, leading to a protracted absence of Spanish diplomatic acceptance. The Act's legal standing was invoked in negotiations such as the later Adams–Onís Treaty context and colored Spanish attempts to reassert influence, including royalist holdouts in Chiapas and episodic conflicts in Veracruz and Oaxaca.

Legacy and Historical Significance

The Solemn Act is commemorated as a foundational moment in Mexican national identity, cited alongside the insurgent campaigns of Miguel Hidalgo y Costilla and José María Morelos in patriotic narratives and civic rituals such as Día de la Independencia (Mexico). Historians situate the Act within the broader Atlantic-era pattern of independence declarations including those of Haiti, Venezuela, Argentina, and Brazil, noting similarities and divergences in monarchical proposals and clerical influence. Its legal and symbolic legacy influenced debates during the Federalist and Centralist conflicts, the framing of the Constitution of 1824, and later revisions in the mid-19th century during the Reform War and interventions involving France and the United States. The document remains a primary source for scholars studying the transition from colonial administration of the Viceroyalty of New Spain to the republic and empire configurations that shaped modern Mexico.
