When Muhammad Ali, then known as Cassius Clay, first fought champion Sonny Liston, it resulted in a great upset as Clay knocked off one of the most feared boxers in history. Liston failed to come out for the bell after the sixth round.
It was immensely controversial with many people believing that the fight was fixed. After the fight, Ali publicly embraced Islam and Elijah Muhammad, which, in 1964, was hugely controversial.
The rematch was first to be in Boston but for various reasons, it was moved to Lewiston, Maine, a town of about 40,000.
The rematch didn't last two minutes and ended with even more controversy: many people believed that the punch Ali threw to knock Liston down either didn't connect or never connected at all.
