Benjamin is a donkey in George Orwell's novel Animal Farm. He is also the oldest of all the animals (he is alive in the last scene of the novel). He is less straightforward than most characters in the novel, and a number of interpretations have been put forward to which social class he represents as regards to the Russian Revolution and the Soviet Union. (Animal Farm is an allegory for the evolution of Communism in Russia, with each animal representing a different social class, e.g. Boxer represents the working class)
Some interpret Benjamin as representing the aged population of Russia, because he is old and cynical. Others feel that he represents the Menshevik intelligentsia as he is just as intelligent, if not more so, than the novel's pigs, yet he is marginalized. He is very cynical about the Revolution and life in general. It has also been argued that he represents the skeptical people who believed that Communism would not help the people of Russia, but who did not criticize it fervently enough to lose their lives. His Biblical name could also imply that he represents the Jewish populace of Russia whose lives were not remotely improved under Joseph Stalin's leadership.
He is one of the wisest animals on the farm and is able to "read as well as any pig". However, he rarely uses his ability, because he feels there is nothing worth reading. He does not use his ability for the benefit of others until the end of the book, when Boxer is sent off to the slaughterhouse, and when Clover asks him to read the public display of the Seven Commandments, as they, for the last time in the book, changed; Benjamin reveals that the Commandments now consist entirely of the message "All animals are equal, but some animals are more equal than others". Despite his age, he is never given the option of retirement (none of the animals are). Only the pigs' betrayal of his best friend, Boxer, spurs him into (failed) action, after which Benjamin becomes more cynical than ever.
