Augustin Alfred Joseph Paul-Boncour (French:[ʒozɛfpɔlbɔ̃kuʁ]; 4 August 1873 – 28 March 1972)[1] was a French politician and diplomat of the Third Republic. He was a member of the Republican-Socialist Party (PRS) and served as Prime Minister of France from December 1932 to January 1933. He also served in a number of other government positions during the 1930s and as a Permanent Delegate to the League of Nations in 1936 during his tenure as Minister of State.
Turning to Socialism, he joined the SFIO in 1916. Paul-Boncour left the socialist party in 1931 because he considered imperative, in face of the League of Nations progressive powerlessness, to reinforce national defence, something the socialists opposed.[2] After his resignation from the SFIO in 1931 he joined the Republican-Socialist Party (PRS), which in 1935 merged with the French Socialist Party (PSF) and the Socialist Party of France-Jean Jaurès Union (PSdF) to form the Socialist Republican Union (USR). Also in 1931, Paul-Boncour was elected to the Senate, and served in that capacity until the establishment of the Vichy régime in 1940 (during World War II).
During his time as a Senator, Paul-Boncour served in a variety of cabinet and diplomatic posts. He was the Permanent Delegate to the League of Nations from 1932 to 1936, Minister of War in 1932, Premier from December 1932 to January 1933, and Foreign Minister on two occasions (December 1932 to January 1934 and March–April 1938).
