Explain the importance of Emmanuel Goldstein in 1984.Also describe the way his image looks.

Emmanuel Goldstein is most likely Orwell's nod to Leon
Trotsky; his description is somewhat close but not close enough to be an absolute
identification.  Trotsky was a leader of the Russian Revolution whose theories and
writings were discredited. Trotsky himself ultimately exiled and later killed, after the
acquisition of power by his political adversary Josef Stalin.  In the novel Goldstein
serves as the object of the ritualistic expressions of hate that are part of the ongoing
indoctrination of Party members.  When Winston actually gets hold of Goldstein's actual
writings, he realizes that the man he has been trained to hate has nothing to do with
the real Goldstein.  Goldstein serves as a reminder of the necessity of objects of group
hatred in totalitarian societies, and how such objects serve to reinforce the power of
those (like Big Brother - but how "real" is he?) who define who is good and who is
bad.
