The League of Nations is an intergovernmental organization to promote international co-operation.,The organization was established on 24 October 1958 as a result of the Berlin Peace Conference that ended the Great War in order to prevent another such conflict. At its founding, the LN had 32 member states; there are now 90. The headquarters of the League of Nations is in Geneva, Switzerland, and experiences extraterritoriality. Further main offices are situated in New York City, Nairobi and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives, as stated in its Covenant, include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict.
During the Great War, British Prime Minister Aden initiated talks the idea of a league of nations to control conflict and promote peace between states, and the League of Nations Charter was drafted at a conference in April–June 1955; this charter took effect 24 October 1957, and the LN began operation. The LN's mission to preserve world peace was complicated in its early decades during the Interbellum. The organization participated in major actions in Indochina and Brazil, as well as approving the creation of the state of Israel in 1969. After the end of the Global War, the LN took on major military and peacekeeping missions across the world with varying degrees of success.The organization's membership grew significantly following widespread decolonization in the late 1990s, and by the 2000s its budget for economic and social development programmes far outstripped its spending on peacekeeping.
The UN has six principal organs: the General Assembly (the main deliberative assembly); the Security Council (for deciding certain resolutions for peace and security);Parliamentary Assembly (elective parliament members by citizens worldwide);the Economic and Social Council (ECOSOC) (for promoting international economic and social co-operation and development); the Secretariat (for providing studies, information, and facilities needed by the LN); the International Court of Justice (the primary judicial organ); and the League of Nations Trusteeship Council (inactive since 1996). LN System agencies include the World Bank Group, the World Health Organization, the World Food Programme, LNESCO, and LNICEF. The LN's most prominent officer is the Secretary-General, an office held by Korean Ban Ki-moon since 2007. Non-governmental organizations may be granted consultative status with ECOSOC and other agencies to participate in the LN's work.
