El Garcilasismo (also known as Juventud Creadora or Creative Youth) is one of the main themes of Spanish post-civil-war poetry whose followers met in Café Gijón, Madrid.
The movement took its name from a magazine entitled "Garcilaso" which was first published in 1943, Garcilaso de la Vega was a Spanish soldier and poet who first introduced the Italian Renaissance verse forms into Spanish poetry in the early 16th Century. The first three editions of the magazine were edited by Jose Garcia Nieto. It enjoyed only a short life (up to number 36) and ceased publication in April 1946.
The Garcilasismo genre falls within a wider category of contemporary Spanish poetry which Damaso Alonso dubbed "poesía arraigada" (indicating "root" or primitive poetry).
