The Unified Socialist Party (French: Parti Socialiste Unifié, PSU) was a socialist political party in France, founded on April 3, 1960. It was originally led by Édouard Depreux (from its creation to 1967), and by Michel Rocard (1967–1973).
PSU was born through the fusion of the Autonomous Socialist Party (PSA), the Socialist Left Union (UGS), and the group around the journal Tribune du Communisme. The latter was a splinter-group of the French Communist Party (PCF), which had left after the 1956 inner conflict caused by the Soviet invasion of Hungary. The PSA and the UGS was a splinter-group of the French Section of the Workers' International (SFIO) party, which had left in due to the repressive policy of the SFIO Prime Minister Guy Mollet during the Algerian War of Independence and his support to General Charles de Gaulle's return and the advent of the Fifth Republic under the military pressure. The three groups were closely linked from 1958. In 1961, the newly formed party was joined by Pierre Mendès-France, after he had left the Radical Party, and by Alain Savary, a former SFIO member as opposed as Mendès-France was to Charles de Gaulle's return to power in the turmoil of the May 1958 crisis.
