Carlos Martínez Rivas (1924-1998) was a Nicaraguan poet and is widely considered one of his country's most important writers of the twentieth century. All of his works, except La insurrección solitaria [The solitary insurrection] (1953), remained unpublished until the recent publication of his Poesía Reunida [Collected poetry] (Anamá, 2007). Despite this effort, he remains virtually unknown in Latin America, and even more so in the English-speaking world.
