Riding with the Revolution tells the story of Americans who from 1900 to 1925 became involved with the Mexican Revolution. John Reed actually saddled up and rode with Pancho Villa. Later, American war resisters crossed the Rio Grande into Mexico, where they helped found the Communist Party, the Industrial Workers of the World, and a Feminist Council. Protestant ministers, Socialist Eugene Debs, Samuel Gompers head of the AFL, the anarchist Emma Goldman, and Communists John Reed, Louis Fraina, Bertram Wolfe, as well as foreign politicos M.N. Roy, Sen Katayama, and Alexander Borodin all took a hand in the Mexican labor movement.
