He was a man who fought like no other inside the ring, yet outside the ring he fought for peace. "The Louisville Lip" went on to become a three-time champion, beating some of boxing's greatest fighters, including Joe Frazier and George Foreman. He stunned the world when he beat Sonny Liston for the title. He stunned the world even more when he joined the Nation of Islam and changed his name to Muhammad Ali. He was stripped of his title and banned from boxing for refusing to join the military because of his religious beliefs, then returned to become one of the most famous athletes in history. Not even Parkinson's disease could stop him. A fighter, poet, civil rights leader, humanitarian, and more, Ali remains, in his own words, the king of the world.
