Aristide Briand was born in the port city of Nantes and became one of the most famous leaders of the French Socialist Party. He served eleven times as prime minister during the both the First World War and the difficult times that followed. He was awarded the Nobel Peace Prize in 1926 for his role in the Treaty of Locarno and also authored the Kellogg-Briand Pact, with U.S. Secretary of State Frank Kellogg, that outlawed war. He died in March 1932. (By John Osborne)
