The League of Revolutionary Black Workers was a Marxist-Leninist organization of Black autoworkers, students, and intellectuals in Detroit that brought revolutionary politics directly onto the factory floor. It grew out of a wildcat strike at Chrysler's Dodge Main plant in May 1968. Black workers there, given the hardest and most dangerous jobs and ignored by a union leadership that tolerated racism on the line, formed the Dodge Revolutionary Union Movement, DRUM. Revolutionary union movements soon spread to other plants: ELRUM at Eldon Avenue Gear and Axle, FRUM at Ford's River Rouge complex, and many more. In 1969 they united as the League.

Led by organizers including General Baker, Ken Cockrel, Mike Hamlin, John Watson, Luke Tripp, and John Williams, the League argued that Black workers stood at the point of production and at the bottom of American society. That position made them the vanguard of the working-class revolution. They fought the auto companies and the United Auto Workers bureaucracy at once, through wildcat strikes, leaflets, and plant-by-plant organizing. The League also understood cultural work as part of the struggle. It published the Inner City Voice and for a time ran Wayne State University's student newspaper, the South End. It built a printing press and a bookstore, and with Newsreel it produced the documentary Finally Got the News, which carried the voices of Black workers to audiences across the country and the world.

The League split in 1971 over questions of strategy and direction, but its influence ran deep. It showed that revolutionary organizing could be rooted in the workplace and led by Black workers themselves, and that the fight against racism and the fight against capitalism were one fight. Its legacy lives on in rank-and-file labor movements, in Black workers' organizing today, and in the conviction that those who produce the world's wealth have the power to change it.
