On July 21, 1971, one of the most iconic fights in boxing history took place at Madison Square Garden in New York City. It was the "Fight of the Century" between undefeated heavyweight champions, Muhammad Ali and "Smokin'" Joe Frazier.

The fight was highly anticipated, as both fighters were at the peak of their careers. Ali, known for his quick wit, charisma, and unparalleled boxing skills, had recently returned to the ring after a three-and-a-half-year suspension due to his refusal to be drafted into the U.S. military during the Vietnam War. Frazier, on the other hand, was the reigning heavyweight champion, known for his relentless fighting style and devastating left hook.

The atmosphere inside Madison Square Garden was electric, with celebrities like Frank Sinatra and Burt Lancaster in attendance. The fight lived up to its hype, as both fighters engaged in a brutal, 15-round battle. Frazier dominated the early rounds, landing his signature left hook and forcing Ali to fight off the ropes. Ali, however, came back in the middle rounds, using his superior speed and footwork to outbox Frazier.

In the end, it was Frazier who emerged victorious, winning by unanimous decision and handing Ali his first professional loss. The image of Frazier knocking down Ali with a vicious left hook in the 15th round has become one of the most iconic moments in sports history.

The fight not only solidified Frazier's place in boxing history but also marked a significant moment in Ali's career. Ali would go on to win the rematch against Frazier in 1974 and then shock the world by defeating George Foreman in the "Rumble in the Jungle" later that year to regain the heavyweight title.

The "Fight of the Century" remains a testament to the skill, courage, and determination of two of the greatest boxers of all time, and its legacy continues to inspire athletes and fans around the world to this day.
