The military dictatorship in Brazil () was established on 1 April 1964, after a coup d'état by the Brazilian Armed Forces, with support from the United States government, against President João Goulart. The Brazilian dictatorship lasted for 21 years, until 15 March 1985. The military coup was fomented by José de 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. The coup 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-communist 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.
