The creation of the League of Nations after World War I was based on the theory that collective security and international cooperation could prevent future conflicts. Proposed by U.S. President Woodrow Wilson, the League aimed to foster dialogue among nations, reduce arms, and resolve disputes peacefully. It represented a shift from the traditional emphasis on national sovereignty to a more interconnected approach to global governance. Although the League faced challenges, including the absence of the United States, it laid the groundwork for future international organizations like the United Nations, reflecting the ongoing pursuit of peace and stability in global affairs.
