George Orwell was a novelist, essayist and critic best known for his novels Animal Farm and Nineteen Eighty-Four. He was a man of strong opinions who addressed some of the major political movements of his times, including imperialism, fascism and communism. Animal Farm was published in 1945 when Orwell, a democratic socialist, was angered at Joseph Stalin for betraying the ideas of the Russian Revolution. In fact, that is the basis of Orwell's book. The characters in Animal Farm resemble significant people that impacted the Russian Revolution. These characters act similarly to the real people and actions that were done in the past. Through this book, George Orwell exposes Stalin's true nature and evils using a corrupt pig named Napoleon that eventually dictates the farm. Animal Farm is one of the most influential political texts ever written.
