Jack Johnson was the first African American heavyweight boxing champion, holding the title from 1908 to 1915. He was known for his dominance in the ring, as well as his flamboyant lifestyle and defiance of racial norms. Johnson's success in a predominantly white sport made him a controversial figure, facing backlash and discrimination both inside and outside of the ring.

Johnson's victory over Tommy Burns in 1908 to claim the heavyweight title was a significant moment in Black history, as it challenged the prevailing racial attitudes of the time. However, his flamboyant lifestyle, relationships with white women, and open disregard for societal rules led to intense scrutiny and persecution. In 1913, Johnson was convicted under the Mann Act for transporting a white woman across state lines for "immoral purposes," a charge widely viewed as racially motivated.

Despite the challenges he faced, Jack Johnson paved the way for future generations of Black athletes to compete at the highest levels of sports. His impact on boxing and his defiance of racist conventions make him a significant figure in Black history.
