Homage to Catalonia is political journalist and novelist George Orwell's personal account of his experiences and observations in the Spanish Civil War. The first edition was published in 1938. The book was not published in the United States until February 1952. The American edition had a preface written by Lionel Trilling. The only translation published in Orwell's lifetime was into Italian, in December 1948. A French translation made by Yvonne Davet – with whom Orwell corresponded, commenting on her translation and providing explicatory notes – in 1938-39, was not published until five years after Orwell's death.

Orwell served as a private, a corporal, or cabo and—when the informal command structure of the militia gave way to a conventional hierarchy in May 1937—as a lieutenant, on a provisional basis, in Catalonia and Aragon from December 1936 until June 1937. In June 1937 the leftist political party with whose militia he served (the POUM, the Workers' Party of Marxist Unification, an anti-Stalinist communist party) was declared an illegal organization and Orwell was consequently forced to flee or face imprisonment. Having arrived in Barcelona on 26 December 1936 he told John McNair, the Independent Labour Party's representative there, that he had "come to Spain to join the militia to fight against Fascism." He also told McNair that "he would like to write about the situation and endeavour to stir working class opinion in Britain and France." McNair took him to the POUM barracks, where Orwell immediately enlisted. "Orwell did not know that two months before he arrived in Spain, the NKVD's resident in Spain, Aleksandr Orlov, had assured NKVD Headquarters, 'the Trotskyist organisation POUM can easily be liquidated' - by those, the Communists, whom Orwell took to be allies in the fight against Franco."

Catalonia (English /kætəˈloʊniə/, /kætəˈloʊnjə/; Catalan: Catalunya [kətəˈɫuɲə] or [kataˈluɲa]; Spanish: Cataluña [kataˈluɲa]; Occitan: Catalonha [kataˈluɲɔ]) is an autonomous region of Spain in the north-east of the Iberian Peninsula, with the official status of a "nationality". Catalonia comprises four provinces: Barcelona, Girona, Lleida, and Tarragona. Its capital and largest city is Barcelona which is the second largest Spanish city by population after Madrid. Catalonia covers an area of 32,114 km² and has an official population of 7,535,251. Its borders essentially reflect those of the former Principality of Catalonia. It borders France and Andorra to the north, Aragon to the west, the Valencian Community to the south, and the Mediterranean Sea to the east (580 km coastline). The official languages are Catalan, Spanish and Aranese (Occitan).

The name Catalunya (Catalonia) began to be used in the late 11th century in reference to the group of counties that comprised the Marca Hispanica. The origin of the term is subject to diverse interpretations. A theory suggests that Catalunya derives from the term "Land of Castles", having evolved from the term castlà, the ruler of a castle (see castellan). This theory therefore suggests that the names Castile and Catalonia have the same etymology.

Eric Arthur Blair (25 June 1903 – 21 January 1950), better known by his pen name George Orwell, was an English novelist and journalist. His work is marked by keen intelligence and wit, a profound awareness of social injustice, an intense opposition to totalitarianism, a passion for clarity in language and a belief in democratic socialism.

Considered perhaps the 20th century's best chronicler of English culture, Orwell wrote literary criticism, poetry, fiction and polemical journalism. He is best known for the dystopian novel Nineteen Eighty-Four (1949) and the allegorical novella Animal Farm (1945), which together have sold more copies than any two books by any other 20th-century author. His book Homage to Catalonia (1938), an account of his experiences in the Spanish Civil War, is widely acclaimed, as are his numerous essays on politics, literature, language and culture. In 2008, The Times ranked him second on a list of "The 50 greatest British writers since 1945".

Orwell's influence on popular and political culture endures, and several of his neologisms, along with the term Orwellian—a byword for totalitarian or manipulative social practices—have entered the vernacular.
