On April 28, 1967, Muhammad Ali —then still known to many by his birth name, Cassius Clay —reported to Local Board No. 61 in Houston for induction into the U.S. armed forces. The 25-year-old heavyweight champion spent the morning filling out forms and receiving a physical exam. In the afternoon, when his name was called, he did not step forward. He wrote down his reason: “I refuse to be inducted into the armed forces of the United States because I claim to be exempt as a minister of the religion of Islam.” He meant the Nation of Islam, the black separatist organization headed by Elijah Muhammad, also known as the Messenger.
Ali was swiftly convicted of draft evasion, a felony. Remaining free while his lawyers pursued appeals, he became a generational flashpoint—a reliable gauge of political views on the Vietnam War.
For every athlete who wishes to “make a statement” today, and plenty do, no exemplar looms larger than Ali. He paid a steep price for his stand: Spurning due process, boxing commissions stripped him of his title and banned him from the sport for 3½ years. This meant losing millions of dollars in the prime of his career.
