René Pleven (French pronunciation: ​[ʁəne pləvɛ̃]; 15 April 1901 – 13 January 1993) was a notable French politician of the Fourth Republic. A member of the Free French, he helped found the Democratic and Socialist Union of the Resistance (UDSR), a political party that was meant to be a successor to the wartime Resistance movement. He served as prime minister twice in the early 1950s, where his most notable contribution was the introduction of the Pleven Plan, which called for a European Defence Community between France, Italy, West Germany, and the Benelux countries.
