Pierre-Étienne Flandin (born April 12, 1889, Paris, France—died June 13, 1958, Saint-Jean-Cap-Ferrat) was a lawyer, politician, and several times a minister during the final years of France’s Third Republic.
Flandin was a deputy from 1914 to 1940 and, in addition, held various ministerial posts. He also served as premier from November 1934 to May 1935. When in March 1936 the Germans sent their troops into the Rhineland, Flandin, as foreign minister, suggested the use of French armed forces to evict them, but he was supported by only a minority of ministers. His failure to induce the French and British governments to act convinced him that Germany would dominate Europe and that France should accept the inevitable.
In the Vichy regime Flandin was associated with the more moderate collaborators. They succeeded in bringing him into the government as foreign minister in Pierre Laval’s place, but his inclusion lasted only until February 1941, when Admiral Jean Darlan replaced him. After the liberation of France, the high court of justice in 1946 acquitted him of treason and sentenced him to five years of “national unworthiness” but remitted this sentence on account of some services he had rendered to the Résistance.
