After World War I, the United States, Italy, France, and Great Britain participated in the 1919 Paris Peace Conference, where they negotiated the Treaty of Versailles and other agreements to formally end the war. The treaty imposed heavy reparations and territorial losses on Germany. Additionally, these nations sought to reshape the political landscape of Europe, with the aim of preventing future conflicts, although the outcomes often sowed the seeds for future tensions. They also established the League of Nations to promote diplomacy and collective security, although the U.S. ultimately did not join.
