The primary outcome of the Paris Peace Conference in 1919 was the establishment of the Treaty of Versailles, which formally ended World War I. This treaty placed significant reparations and territorial losses on Germany, reshaping Europe's political landscape. The conference aimed to establish a framework for lasting peace through the creation of the League of Nations, an institution designed to foster international cooperation and prevent future conflicts. However, the punitive measures imposed on Germany contributed to economic hardship and political instability, setting the stage for the rise of extremism and World War II.
