The end of World War I left the victorious Allied Powers needing to formalize peace terms with the defeated Central Powers. US President Woodrow Wilson had commissioned research and developed his Fourteen Points in 1917, which served as the basis for the German surrender and the Armistice of 11 November 1918, setting the agenda for subsequent negotiations.
Beginning on 18 January 1919 in Paris, diplomats from 32 countries convened under the dominance of the 'Big Four' — Clemenceau, Lloyd George, Wilson, and Orlando. They produced five peace treaties, created the League of Nations, redrew national boundaries across Europe, Asia, Africa, and the Pacific, transferred German and Ottoman colonial possessions as mandates, and imposed reparations on Germany via Article 231 of the Treaty of Versailles.
The defeated Central Powers, excluded from deliberations, harbored deep resentments over the terms imposed. Germany's 'war guilt' clause and heavy reparations, only partly paid before payments ceased after 1931, fueled political instability. These conditions contributed directly to the rise of extremist movements and are widely regarded as a leading cause of World War II.
