Orwell is best known for his allegorical novella Animal Farm (1945) and the dystopian novel Nineteen Eighty-Four (1949), although his works also encompass literary criticism, poetry, fiction and polemical journalism. His non-fiction works, including The Road to Wigan Pier (1937), documenting his experience of working-class life in the industrial north of England, and Homage to Catalonia (1938), an account of his experiences soldiering for the Republican faction of the Spanish Civil War (1936–1939), are as critically respected as his essays on politics, literature, language and culture.
