In a narrative that spans the globe and more than two centuries of history, Mark Steven traces the history of class war from the Haitian Revolution to Black Lives Matter. Surveying the literature of revolution, from the poetry of Shelley and Byron to the novels of Emile Zola and Jack London, and exploring the writings of Frantz Fanon, Che Guevara, and Assata Shakur, Class War reveals the interplay between military action and the politics of class, showing how solidarity flourishes in times of conflict. Written with verve and ranging across diverse historical settings, Class War tells the stories of those whose actions can help guide future militants toward a revolutionary horizon.
