The historic boxing rivalry between Muhammad Ali (formerly Cassius Clay) and Joe Frazier captivated the world throughout the 1960s and 1970s. Their first epic encounter, dubbed the "Fight of the Century," took place on March 8, 1971, at Madison Square Garden in New York City. Both fighters were undefeated at the time, with Ali returning to the ring after a forced hiatus due to his refusal to be drafted into the Vietnam War. The bout went the distance, with Frazier delivering a decisive left hook in the 15th round that sent Ali to the canvas, securing a unanimous decision victory for Frazier.

Their rivalry continued with two more legendary bouts, including the infamous "Thrilla in Manila" in 1975, where Ali emerged victorious after a grueling 14-round battle in the sweltering heat of the Philippines. The rivalry between Ali and Frazier transcended sport, symbolizing larger societal and cultural conflicts of the era.

Sonny Liston vs. Floyd Patterson marked another iconic chapter in boxing history. Liston, a formidable heavyweight known for his intimidating presence and powerful punches, faced off against Patterson, a former Olympic gold medalist and heavyweight champion. Their first encounter in 1962 ended swiftly, with Liston knocking out Patterson in the first round to claim the heavyweight title.

Their rematch a year later followed a similar pattern, with Liston dominating Patterson once again, this time ending the fight in the first round with a devastating knockout. Liston's victories solidified his reign as one of the most fearsome heavyweight champions of his era, while Patterson's valiant efforts endeared him to fans despite the outcomes. The matchups between Liston and Patterson showcased the brutal beauty of heavyweight boxing during a turbulent period in the sport's history.
