Third Portuguese Republic

The Third Portuguese Republic, commonly known as Portugal, was a short lived state established after the Carnation Revolution and the overthrow of the Estado Novo Regime, and lasted until 1977, after the independence of Alentejo and Algarve and Lusitania.

Carnation Revolution and the PREC
From 1932 to 1974, Portugal was dominated by an oppressive regime led by António de Oliveira Salazar and, following his fall from a chair, Marcello Caetano. By 1974, the country was in the Portuguese Colonial War, where Portugal tried to hold its colonies in Angola, Mozambique and Guinea Bissau.

In the night of 24th of April 1974, a group of military personal started a coup to this regime, that ended on 25th of April 1974, with a victory of the Armed Forces Movement (MFA) and being a mostly peaceful revolution. The MFA established the National Salvation Junta, with António de Spínola as President. The political polarization was too much and after a failed protest organized by Spínola where he wanted to appeal to a "silent majority" that sided with his ideas, Spínola resigned as President, being replaced by General Costa Gomes. Spínola later tried to organize a coup, but it failed badly and so Spínola was exiled.
