United Nations Day commemorates the anniversary of the activation of the United Nations Charter on October 24, 1945. The name “United Nations,” coined by United States President Franklin D. Roosevelt, was first used in the “Declaration by United Nations” on January 1, 1942, during the Second World War, when representatives of 26 nations pledged their governments to continue fighting together against the Axis Powers.
The United Nations officially came into existence on October 24, 1945, when the Charter had been ratified by China, France, the Soviet Union, the United Kingdom, the United States and a majority of other signatories.
