Third Portuguese Republic
The Third Republic (Portuguese: Terceira República) is a period in the history of Portugal corresponding to the current democratic republic installed after the Carnation Revolution of 25 April 1974, that put an end to the paternal autocratic regime of Estado Novo of António de Oliveira Salazar and Marcelo Caetano. It was initially characterized by constant instability and was threatened by the possibility of a civil war during the early post-revolutionary years.
