Young Muhammad Ali, then known as Cassius Clay, knocked
out opponent Sonny Liston for his first world title in boxing
on this day in history, Feb. 25, 1964.
According to History.com, twenty-two-year-old Clay achieved
the unthinkable by dethroning Liston, who was then the world
heavyweight boxing champion.
Ali beat the steep odds by winning the fight in a seventh-round
technical knockout.
