Ali won an Olympic gold medal in 1960 and the world heavyweight title in 1964. Following his suspension for avoiding military duty, Ali recovered the heavyweight championship twice more throughout the 1970s, defeating Joe Frazier and George Foreman in the process. His career was ended by a diagnosis of Parkinson's disease in 2016.
Ali first won the gold medal at the Helsinki Olympics in 1960, when he was just 25 years old. He went on to have a very successful professional boxing career, winning the world heavyweight championship four times in all. The first three wins were by knockout, and the last one by decision. Ali defended the title nine times in all, most recently in 1975. He lost it to Frazier in what is considered by many to be the greatest fight in boxing history. After losing the title, Ali regained it twice more before being defeated for the fourth and final time by Foreman in 1974.
During this time, Ali also participated in several important social movements. He joined the civil rights movement in the South, where he received multiple threats to his life because of his appearance and his involvement with the cause. In 1967, he became the first boxer to be suspended by the Nevada Athletic Commission for refusing to serve in the Vietnam War. And in 1971, he became a Muslim after marrying Sonji Blagojevic.
Muhammad Ali (1942–2016) was an American former heavyweight champion boxer and one of the twentieth century's most influential sports stars. Ali was an Olympic gold winner and the first boxer to win the heavyweight belt three times in his 21-year professional career. He also held the titles at least once each in four other weight classes.
Ali first gained attention as a young man when he fought several matches against other boxers while still under contract to work for the U.S. Army. In those fights, which included bouts in Japan and Germany, he established himself as a talented fighter who could take a punch. After leaving the army, Ali turned pro and became one of the world's best heavyweights. In 1964, he was named the Light Heavyweight Champion by the World Boxing Association (WBA). However, the title was later stripped from him due to a contract dispute with then WBA Heavyweight Champion Sonny Liston.
In February 1967, just over a year after losing his title, Ali regained it by defeating Liston in what is considered by many to be one of the greatest fights in boxing history. In August of that same year, he won the WBC Heavyweight Championship from Tony Zale. Two months later, he lost this title to Liston again. In 1970, Ali defeated Liston for a third time to end their rivalry.

His career record was awarded as 49-5-0.
After retirement, Ali became involved in politics and religion. He became a Muslim in 1975 and spoke out against the U.S. involvement in the Vietnam War. In 1978, he was stripped of his title after refusing to be drafted into the U.S. Army during the Vietnam War. He regained it in a rematch with Joe Frazier in what many consider to be one of the greatest fights in boxing history. In 2001, Ali was diagnosed with Parkinson's disease.
