1978 Brazilian Parliamentary Election
15 November 1978 · The two-party dictatorship · 422 seats
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.
Held under the military regime's imposed two-party system; competitive, but on the dictatorship's terms.
