The Second Portuguese Republic (), or more commonly known as Estado Novo (, "New State"), was the corporatist regime installed in Portugal in 1933. It evolved from the "Ditadura Nacional" ("National Dictatorship") formed after the "coup d'état" of 28 May 1926 against the democratic and unstable First Republic. Together, the "Ditadura Nacional" and the "Estado Novo" are recognised by historians as the Second Portuguese Republic. The "Estado Novo", greatly inspired by conservative and autocratic ideologies, was developed by António de Oliveira Salazar, who was President of the Council of Ministers from 1932 until illness forced him out of office in 1968.
