Argentina's true break with Spanish tradition was manifested in literature through the adoption of French romanticism as a model, postulating the return to popular sources and to the medieval. This aesthetic and intellectual was brought by Esteban Echeverría who wrote the first local and realistic story, "El Matadero" ("The slaughterhouse"), as well as the nativist poem "La Cautiva" ("The Captive"), with the Pampas as its background. His barbed wit and opposition to powerful Buenos Aires governor Juan Manuel de Rosas forced him into exile.
