The Latin American Boom (Boom latinoamericano) was a literary movement of the 1960s and 1970s when the work of a group of relatively youthful Latin American novelists became widely circulated in Europe and throughout the world. The Boom is most closely associated with Julio Cortázar of Argentina, Carlos Fuentes of Mexico, Mario Vargas Llosa of Peru, and Gabriel García Márquez of Colombia; but it also brought fame to older writers like Jorge Luis Borges, Pablo Neruda and Ernesto Sábato. Influenced by European and North American Modernism, but also by the Latin American Vanguardia movement, these writers challenged the established conventions of Latin American literature. Their work is experimental and, owing to the political climate of the Latin America of the 1960s, often very political. "It is no exaggeration", critic Gerald Martin writes, "to state that if the Southern continent was known for two things above all others in the 1960s, these were, first and foremost, the Cuban Revolution and its impact both on Latin America and the Third World generally, and secondly, the Boom in Latin American fiction, whose rise and fall coincided with the rise and fall of liberal perceptions of Cuba between 1959 and 1971." The sudden success of the Boom authors was in large part because their works were among the first Latin American novels to be published in Europe, by publishing houses such as Barcelona's avant-garde Seix Barral in Spain. Indeed, Frederick M. Nunn writes that "Latin American novelists became world famous through their writing and their advocacy of political and social action, and because many of them had the good fortune to reach markets and audiences beyond Latin America through translation and travel—and sometimes through exile."
