Answer and Explanation:
George Orwell (1903 - 1950) was an English novelist originally born in India. His allegorical novella "Animal Farm", published in 1945, criticized the Soviet regime in Russia and the inequality that resulted from it.
In "Animal Farm", the animals represent the people and the leaders involved in the Russian Revolution. Just like what happened to Russia, the animals of the farm took control by expelling their former human owners. Their purpose was to create a society that was just, equal, and prosperous. Each animal would work for the benefit of all, but none would be mistreated. "All animals are equal" was the most important commandment of their revolution.
However, the pigs being the most intelligent animals among all, they soon took control. And that taste of power made the pigs cruel and ambitious. Progressively, the pigs began to break their own rules, dressing and acting like humans. They also forced the other animals to live and work in awful conditions so that the farm would get some profit. Their ideals and principles soon meant nothing.
There was a clear disparity between the pigs and the other animals - so much for equality. Anyone who showed discontentment would be tried and killed without mercy - so much for justice. And although the farm did make some profit, the animals did not enjoy any of it. Their rations were smaller and smaller, their workload harder and harder - so much for prosperity. In the end, the most important commandment became "all animals are equal, but some are more equal than others."
