Auriol was born in
Revel, Haute-Garonne, as the only child of Jacques Antoine Auriol (1855–1933), a baker nicknamed Paul, and Angélique Virginie Durand (1861–1945). His great-grandmother, Anne Auriol, was a first cousin of English engineer
Isambard Kingdom Brunel. He earned a law degree at the Collège de Revel in 1904 and began his career as a
lawyer in
Toulouse. A committed
socialist, Auriol co-founded the newspaper
Le Midi Socialiste in 1908; he was head of the Association of Journalists in Toulouse at this time. In 1914, Auriol entered the
Chamber of Deputies as a Socialist
deputy for
Muret, a position he retained until 1942. He also served as Mayor of Muret from 3 May 1925 to 17 January 1947, and as a member of the
Conseil Général of
Haute-Garonne from 1928 to 17 January 1947. In December 1920, after the
breakup of the
SFIO, Auriol refused to join the newly created
SFIC and became one of the leaders of the new SFIO (the remaining socialist minority), along with
Léon Blum. Auriol became the party's leading spokesman on financial issues. He chaired the Finance Committee in the Chamber of Deputies from 1924 to 1926. His first cabinet post was as
Minister of Finance under
Léon Blum, in which Auriol controversially devalued the
French franc 30% against the
United States dollar, leading to
capital flight and greater economic unease. This and Blum's proposals for greater regulatory restrictions on industry led to Blum's resignation as
Premier; in the next government, led by
Camille Chautemps, Auriol was made
Minister of Justice, then later he was appointed as Minister of Coordination of Services of the Presidency of the Council in Blum's short-lived government in 1938.
Édouard Daladier's
conservative–
Radical government formed on 10 April 1938 returned Auriol to the Chamber of Deputies. Auriol was one of the
80 deputies who voted against the extraordinary powers given to Prime Minister
Philippe Pétain on 10 July 1940 that brought about the
Nazi-backed
Vichy government. As a result, he was placed under
house arrest until he escaped to the
French Resistance in October 1942, and fought with the resistance for a year. Auriol fled to
London in October 1943. He represented the Socialists at the
Free French Consultative Assembly (organized by
Charles de Gaulle in
Algiers later that year). In July 1944, he represented France at the
United Nations Monetary and Financial Conference at
Bretton Woods, United States. ==Post-war life and presidency==
