"Radio Free Dixie" by Timothy B. Tyson is a non-fiction book that chronicles the life and activism of Robert F. Williams, a prominent Civil Rights leader in the 1950s and 60s. Williams, a North Carolina native, used his position as president of the local chapter of the NAACP to advocate for racial equality and challenge the racist laws and practices of the Jim Crow South. He also started a radio program, "Radio Free Dixie," which broadcasted his message of black liberation and encouraged African Americans to resist oppression and defend themselves against racist violence. The book examines Williams' life and legacy, as well as the broader struggle for civil rights and social justice in the United States during that era.
