Which boxer was famously prosecuted for violating the Mann Act?

The boxer known for being prosecuted under the Mann Act is Jack Johnson. The Mann Act, passed in 1910, was legislation aimed at combating human trafficking, but it was often used in a racially charged manner during the early 20th century. Johnson, who became the first African American heavyweight champion in 1908, faced legal troubles primarily due to his relationships with women, notably a white woman, which led to his arrest and conviction in 1913.

The prosecution was widely regarded as racially motivated, as it targeted Johnson for his defiance of societal norms regarding race. This case highlighted the complex interplay of race, celebrity, and the law during that era, making Johnson a significant figure in both boxing history and the broader context of American social issues. His legal struggles ultimately contributed to discussions about race relations and the legal system in the United States.
