The League of Nations
The League of Nations was an intergovernmental organization founded on January 10, 1920, in the aftermath of World War I. Its primary goal was to promote international cooperation, maintain world peace, and prevent future wars. The League was established under the Treaty of Versailles, which was signed on June 28, 1919, and it was headquartered in Geneva, Switzerland.
The League's main body was the Assembly, which was made up of representatives from all member countries. The League also had a Council, which consisted of the major powers and was responsible for maintaining international peace and security. The League had several specialized agencies, such as the International Labour Organization (ILO) and the World Health Organization (WHO), that worked on specific issues such as labor rights and public health.
Despite its lofty goals, the League was largely ineffective in preventing the outbreak of World War II. The League failed to prevent Japan's invasion of Manchuria in 1931, Italy's invasion of Ethiopia in 1935, and Germany's rearmament and annexation of Austria in 1938. The League also failed to prevent the outbreak of World War II in 1939.
After World War II, the League was dissolved, and its functions were largely taken over by the United Nations, which was established in 1945. However, the League's legacy lived on in the concept of collective security and the idea that international cooperation is necessary to maintain world peace.
