The Revolution of October 8, 1812 (Spanish: Revolución del 8 de octubre de 1812) took place during the Argentine War of Independence. Led by José de San Martín and Carlos María de Alvear, it deposed the First Triumvirate and allowed the creation of the Second Triumvirate, which called the Assembly of Year XIII.
The First Triumvirate was a government of three members that ruled Argentina during the Argentine War of Independence, after the fall of the Junta Grande, which had many members. The Triumvirate had a conservative policy, and had removed the radical supporters of the late Mariano Moreno who promoted the May Revolution and managed government the first months. However, a strong royalist conspiracy headed by Martín de Álzaga made them unite forces once more. Álzaga was defeated and executed, but Morenists returned to the political scene.
The revolutionary war was reinforced by a number of Argentine-born officers who left Spain when the Peninsular War was nearing a total French victory. The most notable of them were José de San Martín and Carlos María de Alvear. They organized a local wing of the Lodge of Rational Knights from Cádiz, and quickly headed the local military forces.
