In 1938, the Spanish poet Rafael Alberti published 'De un momento a otro' (From One Moment to Another), a collection of poems written during the Spanish Civil War that reflected his commitment to the Republic and his growing alignment with the Communist Party. Alberti, one of the leading figures of the Generation of '27, had been a vocal supporter of the Republic from the beginning of the war, and his poetry from this period combined lyrical beauty with political propaganda. The collection was one of the most significant works of Republican poetry.

Alberti's war poetry had a profound impact on Spanish literature, establishing him as the leading poet of the Republican cause. His work, which was widely read and recited, inspired other poets to write in support of the Republic. Alberti's later exile and his continued commitment to left-wing politics also made him a symbol of the generation of poets who were silenced by Franco's victory.
