According to multiple national media outlets, boxing legend Muhammad Ali has died at the age of 74.
Ali died at a Phoenix-area hospital on Friday. He had spent several days being treated for respiratory issues.
The three-time heavyweight champion also had battled Parkinson’s disease since 1984.
In recent years, Ali had largely stayed out of the public spotlight. In his last known appearance, Ali appeared at Parkinson’s fundraiser April 9 in Phoenix, according to the Arizona Republic. A photo posted by the newspaper showed Ali wearing dark sunglasses.
He once was known not only for his athletic prowess as a three-time heavyweight champion but also for his social activism.
Ali was born in Louisville, Kentucky, as Cassius Clay in January 1942. He began boxing as an amateur when he was 12 years old and in 1964 became heavyweight champion with a knockout of Sonny Liston. That year he joined the Nation of Islam and changed his name.
Ali’s sparkling career was interrupted for 3½ years in the 1960s when he refused induction into the U.S. Army during the Vietnam War and was convicted of draft evasion. The Supreme Court overturned the conviction.
He went on to win the heavyweight title twice more before retiring for good in 1981.
