The Brazilian military government was the authoritarian military dictatorship that ruled Brazil from March 31, 1964 to March 15, 1985. It began with the 1964 coup d'état led by the Armed Forces against the administration of the President João Goulart, who had assumed the office after being vice-president upon the resignation of the democratically elected president Janio Quadros, and ended when José Sarney took office as President. The military revolt was fomented by Magalhães Pinto, Adhemar de Barros, and Carlos Lacerda (who had already participated in the conspiracy to depose Vargas on 1954), Governors of Minas Gerais, São Paulo, and Rio de Janeiro, respectively. Brazil’s military regime provided a model for other military regimes and dictatorships around Latin America, systematizing the “Doctrine of National Security,”[1] which "justified" the military’s actions as operating in the interest of National Security in a time of crisis, creating an intellectual basis upon which other military regimes relied.[1]
