How it unfolded
George Foreman was 40-0 with 37 knockouts, having flattened both Joe Frazier and Ken Norton — men who had beaten Ali — in two rounds each. The 32-year-old Ali was rated a clear underdog. Promoter Don King pulled $10 million from Zairean president Mobutu to guarantee each fighter $5 million, and the fight was delayed six weeks after Foreman cut his eye in sparring. To fit US broadcast hours, the opening bell rang at 4 a.m. local time before a crowd of 60,000. Ali greeted Foreman with lead right hands from the first round, then from the second round leaned his own weight onto the ropes, wrapping his arms around his head to absorb Foreman's punishment — the tactic later called rope-a-dope. In Kinshasa's humid heat, Foreman's punches dulled round by round, and just before the eighth round ended Ali counterattacked with combinations and dropped him. The count finished and Ali reclaimed the title after seven years.
Why it still matters
No fight has more dramatically proven that stamina, psychology and tactics can beat raw power. It was also the first mega-event of its scale ever held on the African continent, and it created the template for the modern megafight that combines satellite broadcast with star marketing. Rope-a-dope remains the first thing cited when explaining boxing tactics.
