Brief History of the UN
The United Nations replaced the League of Nations in 1945 with the purpose of promoting peace in the world. After the devastation of World War II, international leaders decided to create a forum that would more effectively allow countries to diffuse conflicts by expanding the scope of the League of Nations.
Currently, the United Nations has 193 member states and operates offices in numerous countries throughout the world. The international headquarters for the United Nations is in New York City and other major offices are in Vienna, Austria; Nairobi, Kenya; and Geneva, Switzerland.
The major topics the United Nations addresses include economic development, global security, international law and human rights. Secretary General, the highest office in the UN, is currently held by Ban Ki-moon of South Korea.
