Andreas Georgiou Papandreou (Greek: Ανδρέας Γεωργίου Παπανδρέου, pronounced [anˈðreas papanˈðreu]; 5 February 1919 – 23 June 1996) was a Greek academic and economist who founded the Panhellenic Socialist Movement (PASOK). He was prime minister of Greece from 1981 to 1989 and again from 1993 to 1996.
Papandreou was the son of Georgios Papandreou. In 1938, Papandreou left Greece for the United States to escape the 4th of August Regime and became a prominent academic. He returned to Greece in 1959 after years of resisting his father's entreaties to prepare him as successor. Papandreou's rapid ascension, together with his uncompromising radical rhetoric, amplified Greece's post-Civil War political instability, which created the conditions for a group of colonels to stage a coup d'état and rule Greece for seven years. Papandreou was imprisoned, then exiled during the ensuing Greek Junta, with many, including his father, blaming him for the fall of democracy. In exile, Papandreou developed and spread an anti-American, conspiratorial narrative of past events, in which he was a victim of larger forces.
