The Estado Novo (Portuguese pronunciation: [(ɨ)ʃˈtadu, -ðu ˈnovu], "New State"), or the Second Republic, was the corporatist authoritarian regime installed in Portugal in 1933, often considered to be fascist. It evolved from the Ditadura Nacional formed after the coup d'état of 28 May 1926 against the democratic and unstable First Republic. Together, the Ditadura Nacional and Estado Novo are recognised as the Second Portuguese Republic. The Estado Novo, greatly inspired by conservative and authoritarian ideologies, was developed by António de Oliveira Salazar, ruler of Portugal from 1932 to 1968, when he fell ill and was replaced by Marcelo Caetano.
