The book "Animal Farm" is an allegorical novel that presents the story of a revolution that went the wrong way, as George Orwell mentions in the first edition of this book in 1945.

According to the author, all animals are equal, but some animals are more equal than others. The animals take action to create a society of progress, justice, and equality. Unfortunately, instead of improving, things get worse. The work becomes harder than before and the revolution collapses.

The pigs walk on their two legs even though they had sworn they would never do so.

The meaning of the story is for ordinary people to understand how ruthless leaders can exploit an entire population if they wish.
