Muhammad Ali was born as Cassius Clay in Louisville, Kentucky. Early in his life, his skills developed from those he needed to stand up to a playground bully into the championship form that earned him a gold medal in the 1960 Olympics. As a professional fighter, Ali became known not just for the speed and agility with which he won three world heavyweight championships, but also for his charm, wit, and showmanship. Outside the ring, the courage of his stand against the military draft made him both a revered cultural hero and a lightning rod for the issues that divided Americans during the Vietnam War. In the decades following his boxing career, Ali has become regarded as one of the most recognized people on the planet. He has lent his name, influence, and generosity to a host of humanitarian causes. Today, having earned the affection of billions of people worldwide, the people's champ is, as ever, The Greatest.
