The UN Charter also shared the ideals and many structural elements on which the League was built. The most remarkable example was that both organizations identified the promotion of international security and the peaceful settlement of disputes as their key goals. The UN has put more emphasis on the economic and social progress of nations than the League, because the Great Depression of the late 1920s was considered the root cause of World War II. As such, in the UN system the economic and social progress of societies has been appreciated for sustaining international security. In order to prevent another devastating war, the founders of the UN defined international security in a broader sense and sought to enable the UN to become active in international politics. Therefore, they identified key areas of the UN as military security, economic and social development, human rights, and international justice (Hanhimaki, 2008: 15- 16). Although the League failed to prevent the outbreak of World War II, the idea of creating an international organization to protect international peace never faded (Mingst and Karns, 2012:21- 22). In fact, the War strengthened the efforts to construct a stronger collective security mechanism at the international level. The UN was also a response to a radically transformed world politics in the wake of  World War II. While the European imperial powers collapsed, the US and Soviet Union emerged from the war as the two superpowers in international politics. Therefore, the UN was formed also to manage this changing international system and power relations between the superpowers as well as the blocs (Hanhimaki, 2008: 13).
