Animal Farm is a political allegory novel written by George Orwell and first published in 1945. The story follows a group of farm animals who overthrow their human owner and establish a socialist society. However, the pigs, who become the leaders of the new society, soon become corrupt and oppressive, leading to a new form of tyranny that is even worse than before.

The novel explores themes such as power, corruption, and the dangers of totalitarianism. It is a scathing critique of the Soviet Union and its leader Joseph Stalin, but also serves as a warning about the potential dangers of any society where a small group holds absolute power.

Animal Farm is widely considered a classic of modern literature and is often studied in schools and universities around the world. Its enduring popularity and relevance have cemented its place as one of the most important works of political fiction in the 20th century.
