Parliamentary elections were held in Brazil on 15 November 1978.[ 1] National Renewal Alliance Party (ARENA) won 231 of the 420 seats in the Chamber of Deputies and 15 of the 23 seats in the Senate . Voter turnout was 82%.[ 2]
They were the last elections held under a mandatory two-party system , as reforms were enacted in 1979 by Brazil's governing military junta , represented in Congress by ARENA, to allow a multi-party system to emerge in an effort to combat the growing popularity of the opposition Brazilian Democratic Movement (MDB) by splitting their vote .[ 3]
In 1977 the electoral system had been reformed, making the election of senators indirect. As with the 1979 reforms, this was primarily done in response to the growth of the Brazilian Democratic Movement.[ 3] [ 4]
