When the United States entered World War II in Europe in 1941, Coca-Cola was as American as apple pie. The United States military put systems in place to do everything it could to ensure its soldiers were never without the refreshing beverage, but things went differently in other countries.

Due to embargos and transportation problems, Coca-Cola couldn't be produced within Germany, so Max Keith, who was in charge of Coca-Cola's German operations, had to improvise. He told his staff to put their imagination to work to create a new beverage, and in 1940, Fanta was born.

Unfortunately, Max Keith wasted no time marketing Fanta to the Nazis, and there were reports of forced labor being used to produce it. Fanta's questionable reputation continued into the 21st century, prompting Coca-Cola to release a statement in 2015 denying its association with the Nazis.
