António de Oliveira Salazar was a Portuguese dictator, academic, and economist who served as the Prime Minister of Portugal from 1932 to 1968. Having come to power under the Ditadura Nacional, he reframed the regime as the corporatist Estado Novo, with himself as dictator. The regime he created lasted until 1974, making it one of the longest-lived authoritarian dictatorships in modern Europe.
