Mexican Independence

The Plan of Iguala (24 February 1821) drafted by Agustín de Iturbide—a royalist officer who had switched sides—offered a conservative settlement: independence under a constitutional monarchy, preservation of the Catholic Church's privileges, and racial equality. The Army of the Three Guarantees swept through New Spain with little resistance, and on 27 September 1821 Iturbide entered Mexico City with his Trigarante army. The Spanish viceroy signed the Declaration of Independence of the Mexican Empire. In 1822 Iturbide was proclaimed Emperor Agustín I, but his empire lasted only until 1823, when a republican rebellion led by Santa Anna forced his abdication.
