What is the main theme of george orwell's novel 'animal farm'?

It is a stinging critique of the history and rhetoric of the Russian revolution and is written in the form of an animal fable.

It is an allegory and the message is about how power can often lead to corruption and oppression

Hope this will help :)

the characters in string all have major secrets that they strive to avoid revealing throughout the play.

what makes a hero is someone who tries and acres and then heps to save people
