What steps did the allies take to prevent world war?

In the aftermath of World War I, the Allies took several steps to prevent another major conflict. They established the League of Nations, aimed at fostering diplomacy and collective security among nations. Additionally, they imposed treaties like the Treaty of Versailles to limit Germany's military capabilities and territorial ambitions. However, these measures ultimately proved insufficient as economic instability and aggressive nationalism in the 1930s undermined peace efforts.
