Early Life and Education of Kamaru Usman
Kamaru Usman was born on May 11, 1987, in Auchi, Edo State, Nigeria. His father, Muhammed Nasiru Usman, was a major in the Nigerian Army, and his mother was a teacher. Usman and his two brothers, Kashetu and Mohammed, experienced a modest upbringing. When Kamaru was eight years old, his father, who had become a pharmacist in the United States, immigrated the family to Dallas, Texas, in search of better opportunities. Adjusting to a new country and culture presented challenges, including learning English. Usman began his athletic journey at Bowie High School in Arlington, Texas, where he started wrestling during his sophomore year. His high school wrestling coach, struggling to pronounce his first name, Kamarudeen, gave him the nickname “Marty,” which he used throughout his amateur wrestling career. He compiled an impressive 53-3 record in high school. After high school, he attended William Penn University before transferring to the University of Nebraska at Kearney (UNK). At UNK, his wrestling career flourished; he became a three-time NCAA Division II All-American and, in his senior year in 2010, won the NCAA Division II National Championship at 174 pounds with a remarkable 44-1 record.
Kamaru Usman’s Career
After a decorated collegiate wrestling career and a near-miss at making the 2012 U.S. Olympic wrestling team due to injuries, Kamaru Usman transitioned to mixed martial arts. He made his professional debut in 2012, winning via TKO. After suffering his first and only loss in his second professional fight, Usman compiled a 5-1 record on the regional circuit. This success earned him a spot on the 21st season of the UFC’s reality show, “The Ultimate Fighter” in 2015. Representing the Blackzilians camp, Usman dominated the competition, defeating Hayder Hassan in the finale via submission to win the tournament and secure a six-figure UFC contract. This victory marked the beginning of a historic run in the UFC’s welterweight division. He debuted officially against a future champion, Leon Edwards, in December 2015, winning by unanimous decision. Usman then methodically climbed the ranks, stringing together a series of dominant victories over notable opponents like Warlley Alves, Demian Maia, and Rafael dos Anjos, showcasing his powerful wrestling and relentless pace. His nine-fight winning streak earned him a title shot against then-champion Tyron Woodley at UFC 235 on March 2, 2019. Usman delivered a masterful, one-sided performance, dominating Woodley for five rounds to win the UFC Welterweight Championship by unanimous decision. This historic win made him the first African-born champion in UFC history. As champion, Usman embarked on a legendary title reign, successfully defending his belt five times. His defenses included two grueling and highly anticipated bouts against Colby Covington, a knockout victory over his former teammate Gilbert Burns, and two wins over Jorge Masvidal, the second of which was a spectacular knockout that earned him Performance of the Night. His 15-fight winning streak is the longest in UFC welterweight history. His reign came to an end in August 2022 at UFC 278, when he was knocked out by Leon Edwards in the final minute of their rematch. He lost the trilogy fight to Edwards at UFC 286 and subsequently moved up to the middleweight division for a bout against Khamzat Chimaev in October 2023, which he lost by majority decision.
