The 1964 Brazilian coup d'état ( or, more colloquially, ) was a series of events in Brazil, from March 31 to April 1, that led to the overthrow of President João Goulart by part of the Armed Forces, supported by the United States. The following day, with the military already in control of the country, Congress came in support of the coup and endorsed it by declaring vacant the office of the presidency. The coup put an end to the government of Goulart, also known as Jango, a member of the Brazilian Labour Party, who had been democratically elected Vice President in the same election that led Jânio Quadros, from the National Labour Party and backed by the National Democratic Union to the presidency.
