The Ditadura Nacional was the name given to the regime that governed Portugal from 1926, after the re-election of General Óscar Carmona to the post of President, until 1933. The preceding period of military dictatorship that started after the 28 May 1926 coup d'état is known as Ditadura Militar (Military Dictatorship). After adopting a new constitution in 1933, the regime changed its name to Estado Novo (New State). The Ditadura Nacional, together with the Estado Novo, forms the historical period of the Portuguese Second Republic (1926–1974).
