A lot of people seem surprised to hear that the term “United Nations,” coined by FDR, was used during WWII.
President Franklin Roosevelt first coined the term “United Nations“ to describe the Allied countries in WWII. On New Year’s Day 1942, FDR, Prime Minister Winston Churchill of Great Britain, Maxim Litvinov of the USSR and T. V. Soong of China, signed the United Nations Declaration. On the next day, the representatives of twenty-two other nations added their signatures. By March 1945, 21 additional states had signed.
