The Allies of World War II often called themselves "the United Nations" (united against the Axis Powers). After the War, the winners formed a new organization for world peace. On 25th April 1945 in San Francisco, they decided on the name '"United Nations". In June they signed the United Nations Charter saying how the organization would work. The UN was created on 24 October 1945 and its first meeting was held in January 1946. Since 1947 the 24th of October has been called “United Nations Day”. The only country whose flag is modelled after the United Nations is Somalia.
