Marvelous Marvin Hagler was one of boxing’s most formidable and respected middleweight champions, known for his granite chin, southpaw stance, and relentless fighting style.

Most people know Marvelous Marvin Hagler from his epic battles against Thomas Hearns and John Mugabi, as well as his controversial split-decision loss to Sugar Ray Leonard. However, it is his escape from riot-torn Newark in the late 1960s, the unbreakable bond he formed with the Petronelli brothers, and his 1980 title fight against Britain’s Alan Minter that captures the real story of Hagler.

After the controversial draw against Vito Antefuermo in 1979, Hagler went on a dominant run and didn’t lose another bout till another controversial decision, a loss to Sugar Ray Leonard in 1987.

Go behind the scenes of the epic battles in “Blood & Hate.”

Marvelous Marvin Hagler’s Classic Fights

1. Hagler vs. Thomas “Hitman” Hearns (April 15, 1985). Dubbed “The War,” this three-round blaze of violence is often called the most incredible short fight in boxing history. From the opening bell, both men launched bombs, but it was Hagler who withstood the punishment, opened a cut, and finished Hearns with a devastating right hand. The fight lasted just 8 minutes, but its legend is eternal.
2. Hagler vs. Roberto Durán (November 10, 1983) A chess match compared to “The War,” this bout showed Hagler’s discipline. Durán became the first man to go the complete 15 rounds with him as champion. Marvin won a close but unanimous decision, retaining his title and adding another Hall of Famer to his resume.
3. Hagler vs. John “The Beast” Mugabi (March 10, 1986). This was a brutal war of attrition. Mugabi entered 25–0 with 25 knockouts, but Hagler dragged him into deep waters, showing veteran composure and a relentless pace before stopping him in the 11th. It was Hagler’s final win—and some say his last great performance.
4. Hagler vs. Sugar Ray Leonard (April 6, 1987): The Controversial Capstone. Leonard used movement, speed, and flurries to win a split decision that many still debate. Hagler, disgusted with the politics of boxing, walked away—never to return.
