The Plan of Iguala, also known as the Plan of the Three Guarantees ("Plan Trigarante") or Act of Independence of North America, was a revolutionary proclamation promulgated on 24 February 1821, in the final stage of the Mexican War of Independence from Spain. The Plan stated that Mexico was to become a constitutional monarchy, whose sole official religion would be Roman Catholicism, in which both the Peninsulares (people born in Spain and residing in Mexico) and the Americanos (people born in Mexico, that is, the Americas) would enjoy equal political and social rights. It took its name from the city of Iguala in the modern-day state of Guerrero.
The two main figures behind the Plan were Agustín de Iturbide (who would become Emperor of Mexico) and Vicente Guerrero, revolutionary rebel leader and later President of Mexico. The Army of the Three Guarantees was formed by the unified forces of Iturbide and Guerrero to defend the ideals of the Plan of Iguala. On 24 August 1821, Iturbide and Spanish viceroy Juan O'Donojú signed the Treaty of Córdoba in Córdoba, Veracruz, ratifying the Plan of Iguala, and thus confirming Mexico's independence.
