Georges Eugène Benjamin Clemenceau (28 September 1841 – 24 November 1929) was a French statesman who served as Prime Minister of France during World War I. A leading figure of the Independent Radicals, he played a central role in the politics of the Third Republic.

Clemenceau was Prime Minister of France from 1906 to 1909 and from 1917 to 1920. Demanding a total victory over Germany, he wanted reparations, colonies, Alsace-Lorraine, and strict rules to prevent Germany from rearming. He achieved these goals in the Treaty of Versailles imposed on Germany at the Paris Peace Conference of 1919.

The Treaty of Versailles was the most important of the peace treaties that brought World War I to an end. The Treaty ended the state of war between Germany and the Allied Powers. It was signed on 28 June 1919 in Versailles, exactly five years after the assassination of Archduke Franz Ferdinand, which had directly led to the war.

Prime Minister of France Georges Clemenceau, Prime Minister of Italy Vittorio Emanuele Orlando, Prime Minister of the United Kingdom David Lloyd George, and President of the United States Woodrow Wilson formed the "Big Four" (at one point becoming the "Big Three" following the temporally withdrawal of Vittorio Emanuele Orlando). These four men met in 145 closed sessions to make all the major decisions, which were later ratified by the entire assembly.
