1978_Brazilian_parliamentary_election
Parliamentary elections were held in Brazil on 15 November 1978.[1] The pro-government 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 81.7%.[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]
