During the early 1890s, a series of shocking lynchings brought unprecedented international attention to American mob violence. This interest created an opportunity for Ida B. Wells, an African American journalist and civil rights activist from Memphis, to travel to England to cultivate British moral indignation against American lynching. Wells adapted race and gender roles established by African American abolitionists in Britain to legitimate her activism as a “black lady reformer”—a role American society denied her—and assert her right to defend her race from abroad. Based on extensive archival research conducted in the United States and Britain, Black Woman Reformer by Sarah Silkey explores Wells’s 1893–94 antilynching campaigns within the broader contexts of nineteenth-century transatlantic reform networks and debates about the role of extralegal violence in American society.
