Latin American literature is a broad and heterogeneous category composed of voices from many countries spanning two continents. In the United States, more attention has been given to Cuban, Chicano/a, and Central American literatures than to writers from other South American countries. This article tries to remedy this disparity by focusing on the presence and influence of literature from South American countries, among them Colombia, Peru, and Argentina. The Latin American Boom was one of the most important literary movements that introduced Latin American literature into the United States and the broader international scene. After the revolution of 1959, Cuba began to offer opportunities for writers and artists from all over Latin America who wanted to pursue their intellectual or artistic interests. One of the reasons the United States government established the Alliance for Progress was to counter Cuba’s influence on Latin American intellectuals. The insidious program Alliance for Progress had a darker side that supported repressive military regimes across Latin America that were responsible for the death, torture and disappearance of thousands of South American citizens. At the same time, it did facilitate the translation and publication of Latin American novels; making them available to the American public. As a result, the works of Colombian, Peruvian, Argentine and Chilean writers such as Gabriel Garcia Marquez, Julio Cortazar, Jose Donoso, Manuel Puig, and Mario Vargas Llosa were published and widely read in the United States. South American literatures have developed a strong presence in the United States such as Andean literature and literature of exile. Since the 1980s, indigenous populations of Peru, Bolivia, and Ecuador have migrated legally or extra-legally to the United States, whether in search of better opportunities or to escape the violence of their home countries. These vibrant Andean populations have contributed to expanding the Andean Archipelago of literature. Similarly, high numbers of Argentines went into exile during the military dictatorship of 1976 to escape government violence and repression. Scholars such as Yossi Shain affirm that exiles expand the borders of the country by creating a diaspora that continues to interact with their compatriots in their home country and with those spread throughout the world. One example is Luisa Valenzuela, an Argentine writer, who continued to be committed to resisting the dictatorship while in exile. Her work is engaged with the process of writing, and how the exile experience influenced her work and her identity.
