The major worldwide event that the Paris Peace Conference aimed to resolve was World War I, which had devastating consequences across Europe and beyond. Convened in 1919, the conference brought together representatives from the victorious Allied Powers to negotiate peace settlements and determine post-war policies. The most significant outcome was the Treaty of Versailles, which imposed heavy reparations and territorial losses on Germany. The conference also established the League of Nations, an international organization intended to promote peace and prevent future conflicts. The decisions made during this conference significantly shaped the geopolitical landscape, setting the stage for World War II.
