1966 Brazilian legislative election

Parliamentary elections were held in Brazil on 15 November 1966.[1] They were the first held since a military coup in 1964. In 1965, the military government of President Humberto de Alencar Castelo Branco shuttered all existing parties, and enacted a new electoral law that effectively limited the number of parties to two—the pro-government National Renewal Alliance and the opposition Brazilian Democratic Movement.
