"Homage to Catalonia" is George Orwell's personal account of his experiences and observations fighting for the POUM militia of the Republican army during the Spanish Civil War. The war was one of the defining events of his political outlook and a significant part of what led him to write in 1946, "Every line of serious work that I have written since 1936 has been written, directly or indirectly, against totalitarianism and for Democratic Socialism, as I understand it".

The first edition was published in the United Kingdom in 1938. The book was not published in the United States until February 1952, when it appeared with an influential preface by Lionel Trilling. The only translation published in Orwell's lifetime was into Italian, in December 1948. A French translation by Yvonne Davet—with whom Orwell corresponded, commenting on her translation and providing explanatory notes—in 1938–39, was not published until five years after Orwell's death.

Eric Arthur Blair (25 June 1903 – 21 January 1950), known by his pen name George Orwell, was an English novelist, essayist, journalist and critic. His work is characterised by lucid prose, biting social criticism, opposition to totalitarianism, and outspoken support of democratic socialism. As a writer, Orwell produced literary criticism and poetry, fiction and polemical journalism; and is best known for the allegorical novella "Animal Farm" (1945) and the dystopian novel "Nineteen Eighty-Four" (1949).
