"Animal Farm" is a novella written by George Orwell that was published in 1945. It tells the story of a group of farm animals who revolt against their human farmer, hoping to create a society where they can be free and equal. The animals establish their own rules and governance, but as time passes, the pigs, who take on leadership roles, begin to exploit the other animals. The story serves as an allegory for the events leading up to the Russian Revolution and critiques the rise of totalitarianism. Through the characters and their experiences, Orwell explores themes of power, corruption, and the betrayal of ideals.
