At the end of the
Mexican War of Independence, the
Army of the Three Guarantees ( or ) was the name given to the army after the unification of the Spanish troops led by
Agustín de Iturbide and the Mexican insurgent troops of
Vicente Guerrero, consolidating Mexico's independence from
Spain. The decree creating this army appeared in the
Plan de Iguala, which stated the three guarantees which it was meant to defend: religion, independence, and unity. Mexico was to be a
Catholic country, independent from Spain, and united against its enemies.
