The daughter of former slaves, Ida B. Wells sued the Chesapeake, Ohio, and Southwestern Railway in 1883 after being dragged from her seat for refusing to move to a segregated railcar. Her anger over this incident spurred her to begin contributing articles to black-owned newspapers; she became part owner and editor of the Memphis Free Speech and Headlight in 1889. After three black businessmen were lynched in Memphis in 1892, Wells launched what became a four-decade-long anti-lynching crusade. She vigorously investigated other lynchings and published her groundbreaking treatise on the topic, Southern Horrors: Lynch Law in All Its Phases.
