This set of essays on Spanish-American avant-garde poetry in the 1920s is the result of many years of collecting materials from various countries and of reflections and writings at various stages of maturation on the subject. The intention is to contribute to the global interpretation of the Spanish-American avant-garde and with this objective these texts explore works from different countries of the continent, thus revealing a surprising network of connections between writers. The essays gathered here present various approaches, such as those that analyse the texts in relation to some literary movements manifested in them such as cubism, surrealism or pure poetry. On the other hand, there are also those who predominantly focus on the mixing of avant-garde with characteristic phenomena of American culture such as cosmopolitanism, criollismo or indigenism, among many others. What all these approaches have in common is that they show the tendency towards cultural mixing and capture the sum of manifestations that as a whole express the complex American cultural identity.
