On July 13, 1971, one of the most controversial boxing matches in history took place at the Houston Astrodome in Texas. It was the "Fight of the Century" between undefeated heavyweight champions, Joe Frazier and Muhammad Ali. This was their third and final match, with each boxer having won one of the previous encounters.

The bout, known as the "Thrilla in Manila," lasted for an incredible 14 rounds under the sweltering Philippine sun. Ali and Frazier pushed each other to their limits, engaging in a brutal and exhausting battle. Ali started strong, using his speed and agility to outbox Frazier in the early rounds. However, Frazier's relentless pressure and powerful left hook began to take their toll on Ali as the fight progressed.

By the late rounds, both fighters were exhausted and battered. Ali's combination of punches had caused Frazier's eyes to swell badly, while Frazier's relentless body shots had drained Ali's energy. In the end, Frazier's trainer, Eddie Futch, refused to let his fighter answer the bell for the 15th round, fearing for his safety. Ali emerged victorious by technical knockout, cementing his legacy as one of the greatest boxers of all time.

The "Thrilla in Manila" is widely regarded as one of the most epic and brutal fights in boxing history. It showcased the incredible skill, determination, and heart of both Ali and Frazier, and remains a testament to the fierce rivalry that defined their careers. The fight also had a lasting impact on both boxers, with Ali later stating, "It was the closest thing to dying that I know of."
