Which led a campaign against lynching?

Ida B. Wells, an African American journalist and civil rights activist, led a prominent campaign against lynching in the late 19th and early 20th centuries. Through her investigative journalism, particularly in her pamphlet "Southern Horrors: Lynch Law in All Its Phases," she exposed the brutal realities of lynching and its motivations, primarily racism and social control. Wells's efforts were instrumental in raising awareness and advocating for anti-lynching legislation, making her a key figure in the fight against racial violence.
