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.
