Early Life and Boxing Beginnings

Cassius Clay began boxing at age twelve to protect himself from bullies. He spent endless hours training and dreaming of becoming the heavyweight champion of the world.

Major Achievements

In 1964, his dream came true when he beat Sonny Liston. Soon after this victory, Clay changed his name to Muhammad Ali.
