Founded in 1945, the United Nations originally had 51 member nations. "United Nations" was coined by US President Franklin D. Roosevelt in the 1942 with the "Document of United Nations" in which 26 representatives of various international governments pledged to fight together against the Axis Powers during World War II (WWII). Prior to the founding of the United Nations, the League of Nations was established under the 1919 Treaty of Versailles during the first World War. The League of Nations was created to promote international peace and security. The organization ended when it failed to prevent the second World War. Since its creation, the United Nations has continued to grow, and as of 2014 has 193 member nations with South Sudan being the latest member in 2011.
