According to historian Mark Thomas Connelly, "a group of books and pamphlets appeared announcing a startling claim: a pervasive and depraved conspiracy was at large in the land, brutally trapping and seducing American girls into lives of enforced prostitution, or 'white slavery.' These white slave narratives, or white-slave tracts, began to circulate around 1909." Such narratives often portrayed innocent girls "victimized by a huge, secret and powerful conspiracy controlled by foreigners", as they were drugged or imprisoned and forced into prostitution.
