Which of these international organization which the predecessor of the United Nations?

The international organization that is considered as the predecessor of the United Nations is the League of Nations. It was founded after World War I in 1920 with the aim of promoting peace and international cooperation among nations. The League of Nations was the first international organization created to maintain world peace and prevent future wars. However, due to its failure to prevent World War II, it was dissolved in 1946 and replaced by the United Nations. The European Economic Community, the Organisation of American States, and the North Atlantic Treaty Organization are not predecessors of the United Nations, but rather different international organizations with different purposes and goals.
