What is an important point was Orwell trying to make in Animal Farm?
Orwell wrote Animal Farm in order to describe the process of corruption in revolution, specially the Russian Revolution.
Orwell’s books expose the dark side of the human condition. He wrote Animal Farm because he wanted to create an allegory, or fable, of the Russian Revolution. He based all of the characters and the events on what actually happened. Therefore, he strongly was convinced that the Russian Revolution was a force of corruption, because that is what he presents of the revolution in Animal Farm.
Using allegory … Orwell made his political statement in a twentieth-century fable that could be read as an entertaining story about animals or, on a deeper level, a savage attack on the misuse of political power. (enotes introduction)
Although Orwell wanted people to realize the abuses that came with the Russian Revolution and the Soviet Union, he also wanted to get people thinking about the nature of revolution in general. Animal Farm’s ending describes how he felt about revolution.
The creatures outside looked from pig to man, and from man to pig, and from pig to man again; but already it was impossible to say which was which. (ch 10)
The pigs promised a better life for the animals, but they abused them and used them just as much as the humans did. In the end, they cannot tell the difference between the humans and the animals. The animals are so corrupt they have basically become human.
Another famous line captures the key to the book and Orwell's beliefs.
There was nothing there now except a single
Commandment. It ran:
ALL ANIMALS ARE EQUAL
BUT SOME ANIMALS ARE MORE EQUAL THAN OTHERS (ch 10)
With this comandment the pigs are able to take over the farm. Orwell wanted people to realize that the Soviets were doing the same thing.
Orwell intentionally wrote his book in simple, easy-to-translate language.
"I thought of exposing the Soviet myth in a story that could be easily understood by almost anyone and which could be easily translated into other languages." (enotes historical background)
Orwell wanted to be sure that no one bought the lies. He was not convinced that the Soviets were telling the truth, and he told the story in such a way that it was obvious who was Stalin, Trotsky, and Hitler. He was writing because he was fed up.
