On Bloody Sunday, March 7, 1965, activist John Lewis led over 600 marchers across the Edmund Pettus Bridge in Selma, Alabama, and faced attacks by state troopers. The confrontation shocked the nation, yet the previous year an even more brutal incident dubbed Bloody Tuesday took place in Tuscaloosa. Historian John M. Giggie examines one of the most violent episodes of the civil rights movement: a pivotal moment in a Southern city unwilling to shed its history of racial control and Klan brutality until forced by armed Black self-defense groups, a bus boycott, and the federal government.
