The Plan of Iguala, also known as The Plan of the Three Guarantees ("Plan Trigarante"), 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 all inhabitants of Mexico would enjoy equal political and social rights. It took its name from the city of Iguala in the modern-day state of Guerrero.
