Enacted in 1910, the Mann Act, commonly referred to as the White Slave Law, was a response to the “white slave panic” of the late 19th and early 20th century. Sold as a way of protecting vulnerable women, this law prohibited the transportation of women across state lines. However, rather than rescue girls forced into prostitution, this law was overwhelmingly used to prosecute consensual interracial relationships and extramarital affairs. The Mann Act profoundly impacted Americans and has ongoing implications for the fight for sex workers’ rights.
