1964 Brazilian coup d'état

The 1964 Brazilian coup d'état (Portuguese: Golpe de estado no Brasil em 1964) was the overthrow of Brazilian president João Goulart by a military coup from March 31 to April 1, 1964, ending the Fourth Brazilian Republic (1946–1964) and initiating the Brazilian military dictatorship (1964–1985). The coup took the form of a military rebellion, the declaration of vacancy in the presidency by the National Congress on April 2, the formation of a military junta (the Supreme Command of the Revolution) and the exile of the president on April 4. In his place, Ranieri Mazzilli, the president of the Chamber of Deputies, took over until the election by Congress of general Humberto de Alencar Castelo Branco, one of the leaders of the coup. Democratically elected vice president in 1960, Jango, as Goulart was known, assumed power after the resignation of president Jânio Quadros, in 1961, and the Legality Campaign, which defeated an attempted military coup to prevent his inauguration.
