The Brazilian military government, also known in Brazil as the Fifth Brazilian Republic, was the authoritarian military dictatorship that ruled Brazil from 1 April 1964 to 15 March 1985. It began with the 1964 coup d'état led by the Armed Forces against the administration of President João Goulart—who, having been vice-president, had assumed the office of president upon the resignation of the democratically elected president Jânio Quadros—and ended when José Sarney took office on 15 March 1985 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 Getúlio Vargas in 1945), then governors of the states of Minas Gerais, São Paulo, and Guanabara, respectively. It was planned and executed by the most forefront commanders of the Brazilian Army and received the support of almost all high-ranking members of the military, along with conservative elements in society, like the Catholic Church and anti-communists civil movements among the Brazilian middle and upper classes. Internationally, it was supported by the State Department of the United States through its embassy in Brasilia.
