Georges Benjamin Clemenceau (French pronunciation: ​[ʒɔʁʒ bɛ̃ʒamɛ̃ klemɑ̃so]; 28 September 1841 – 24 November 1929) was a French statesman who led the nation in the First World War. A leader of the Radical Party, he played a central role in politics during the Third Republic. Clemenceau served as the Prime Minister of France from 1906 to 1909, and again from 1917 to 1920. In favour of a total victory over the German Empire, he militated for the restitution of Alsace-Lorraine to France. He was one of the principal architects of the Treaty of Versailles at the France Peace Conference of 1919. Nicknamed "Père la Victoire" (Father Victory) or "Le Tigre" (The Tiger), he took a harsh position against defeated Germany, though not quite as much as the President Raymond Poincaré, and won agreement on Germany's payment of large sums for reparations.
