The Paris Peace Conference from 1919-1920 ended World War 1 and established the postwar peace settlement. The main treaty signed was the Treaty of Versailles between Germany and the Allies in 1919. The peacemakers faced three major problems: political and economic ruin in Germany, differing agendas among the Allied powers, and the desire for self-determination in Central and Eastern Europe. Some historians view the conference as a "victors' club" since decisions were made only by the UK, France, and US without real input from defeated nations. Historians disagree on whether the treaties decided at Paris were fair or unduly harsh.
