Book excerpt: “This book began in what seemed like a counterfactual intuition . . . that what had been happening in Nicaraguan poetry was essential to the victory of the Nicaraguan Revolution,” write John Beverley and Marc Zimmerman. “In our own postmodern North American culture, we are long past thinking of literature as mattering much at all in the ‘real’ world, so how could this be?” This study sets out to answer that question by showing how literature has been an agent of the revolutionary process in Nicaragua, El Salvador, and Guatemala. The book begins by discussing theory about the relationship between literature, ideology, and politics, and charts the development of a regional system of political poetry beginning in the late nineteenth century and culminating in late twentieth-century writers. In this context, Ernesto Cardenal of Nicaragua, Roque Dalton of El Salvador, and Otto René Castillo of Guatemala are among the poets who receive detailed attention.
