Ion Gheorghe Duca was a Romanian liberal politician, diplomat, and lawyer who briefly served as Prime Minister from November to December 1933. A leading figure in the National Liberal Party, Duca held multiple ministerial roles, including Minister of Foreign Affairs and Minister of the Interior. As Prime Minister, he sought to modernize Romania and strengthen Western alliances but faced severe opposition from the Iron Guard, a revolutionary fascist movement. His crackdown on the group led to his assassination on 30 December 1933. Duca is remembered as an outspoken opponent of fascism, for his commitment to democracy and modernization and as a symbol of interwar Romania’s political turmoil.
