Concept note-1: -The League of Nations (1920 – 1946) was the first intergovernmental organization established “to promote international cooperation and to achieve international peace and security”. It is often referred to as the “predecessor” of the United Nations.
Concept note-2: -As of 20 April 1946, the League of Nations ceased to exist, having handed over all of its assets to the United Nations, and having granted the new UN Secretariat full control of its Library and archives.
Concept note-3: -After some notable successes and some early failures in the 1920s, the League ultimately proved incapable of preventing aggression by the Axis powers in the 1930s. The credibility of the organization was weakened by the fact that the United States never joined, and Japan, Italy, Germany and Spain quit.
Concept note-4: -On April 19, 1946, the League of Nations dissolved, ending 26 years of the existence of an organization which had proven incapable of preventing World War II.
