Muhammad Ali, born Cassius Marcellus Clay Jr., was an iconic American boxer and cultural figure known for his exceptional skills in the ring and his charismatic personality. He became a three-time world heavyweight champion and is widely regarded as one of the greatest boxers of all time. Ali was famous for his quick footwork, powerful punches, and his ability to 'float like a butterfly, sting like a bee.' Beyond boxing, Ali was a prominent civil rights activist, using his platform to advocate for social justice and equality. His refusal to be drafted into the Vietnam War on moral grounds led to a significant legal battle, further solidifying his legacy as a champion both inside and outside the ring.
