The Olympic torch relay was invented by the Nazis. According to historians, Adolf Hitler wanted to promote his belief in an Aryan master race by symbolically linking the 1936 Berlin Games to the ancient Greek gods and rituals, hence the carrying of the flame from Olympia to Germany. The first relay was chronicled on film by Hitler's propagandist, Leni Riefenstahl.
