Miguel Mármol is the testimony of a revolutionary, as recorded by Salvadoran writer, Roque Dalton, which documents the historical and political events of El Salvador through the first decades of the 20th century. This Latin American classic describes the growth and development of the workers' movement and the communist party in El Salvador and Guatemala, and contains Mármol's impressions of post-revolutionary Russia in the twenties, describing in vivid detail the brutality and repression of the Martínez dictatorship and the reemergence of the workers' movement after Martínez was ousted. It also gives a broad and clear picture of the lives of the ordinary peasant and worker in Central America, their sufferings, their hopes and their struggles.
