“Coca-Cola used it. Carlsberg used it on their beer bottles. The Boy Scouts adopted it and the Girls’ Club of America called their magazine Swastika. They would even send out swastika badges to their young readers as a prize for selling copies of the magazine,” he says.

It was used by American military units during World War One and it could be seen on RAF planes as late as 1939. Most of these benign uses came to a halt in the 1930s as the Nazis rose to power in Germany.

The Nazi use of the swastika stems from the work of 19th Century German scholars translating old Indian texts, who noticed similarities between their own language and Sanskrit. They concluded that Indians and Germans must have had a shared ancestry and imagined a race of white god-like warriors they called Aryans.
