This is the first critical, in-depth study of the anarchist movement in Cuba in the three decades after the republic’s independence from Spain in 1898. Kirwin Shaffer shows that anarchists played a significant—until now little-known—role among Cuban leftists in shaping issues of health, education, immigration, the environment, and working-class internationalism. They also criticized the state of racial politics, cultural practices, and the conditions of children and women on the island.
