What progress was made toward world peace in 1920?

In 1920, significant strides were made toward world peace with the establishment of the League of Nations, an international organization aimed at fostering cooperation and preventing conflicts. The League sought to mediate disputes between countries and promote disarmament, reflecting a collective desire for stability following the devastation of World War I. Additionally, the Treaty of Versailles and other peace treaties aimed to address the grievances that had contributed to the war and lay the groundwork for future diplomatic efforts. Despite these efforts, the League faced challenges and limitations that would ultimately hinder its effectiveness.
