At 4:00 a.m. on Oct. 30, 1974, in Zaire, Africa, Muhammad Ali faced "Big" George Foreman—the undisputed heavyweight champion of the world.
The younger, bigger, and stronger Foreman had a record of 40-0 with 37 KOs.
Foreman was heavily favored to win the match.
Ali—who had vowed to dance circles around his more powerful yet slower opponent—came out punching and scoring in round one.
Ali soon abandoned this strategy and retreated to the ropes. He remained there for much of the fight.
Ali invited Foreman to throw everything he had to offer as he laid back on the ropes and blocked many of the powerful bombs. This strategy became known as the "Rope a Dope".
By round eight, Foreman was totally exhausted.
With only 15 seconds remaining in the round, Ali stepped off the ropes and executed a beautiful combination—punctuated with a vicious straight right that sent "Big" George Foreman to the canvas.
Muhammad Ali had accomplished what most had believed to be impossible. He beat George Foreman to regain the title of undisputed heavyweight champion of the world.
