United Abroad, United at Home
President Roosevelt first coined the term "United Nations" to refer to the main 4 countries allied during the war: the United States, Great Britain, Soviet Russia, and China. On January 1, 1942, these four nations signed the United Nations Declaration, which included the Atlantic Charter. The next day, 22 other governments joined the declaration, becoming known as the United Nations.
These countries, besides the main 4 already listed, included: Australia, Belgium, Canada, Costa Rica, Cuba, Czechoslovakia, Dominican Republic, El Salvador, Greece, Guatemala, Haiti, Honduras, India, Luxembourg, Netherlands, New Zealand, Nicaragua, Norway, Panama, Poland, South Africa, and Yugoslavia. During the war, these nations were also known as the Allies. The official UN recognized today was not formed until 1945, just before the war ended.
These types of posters were used to show the American public that other nations were helping to fight the war, and Americans should do all they could to remain unified with the government and each other.
