However, Caliban, one of the primary antagonists of The Tempest, and one of the most developed roles in all of Shakespeare's plays, has other, more important and global influences. Caliban in Arabic means the same as a wild hog/dog, something that makes noise instead it being the follower of something else. A great example would be a mustang, which is a wild horse, not bred to race or be trained to ride humans (a generally accepted position a horse should endeavor). And so, Caliban is a captured immigrant, lured by Prospero and treated like an outcast, a no good and vicious person and in most cases, not even human. I think Shakespeare may have created Caliban's character after reading and witnessing imperialism of the Romani people. He may have been influenced by their exotic and different looks and walks of life. Even though the world is a colossal melting pot, the views of imperialism, its pitfalls and successes, pinpointed that power can do serious damage if not contained. The same goes with Prospero’s desire to always be superior to one another in his crew. Prospero pushes people around, a lot like a child bully, not knowing that it could get the best of him. So, with Prospero’s attitude toward Caliban form the beginning of the play to the end, Caliban gradually grows as one of the lead antagonists, hating on Prospero as his journey becomes more and more treacherous.
If you study civilizations that were taken over by a steady force, like the Aztec’s Civilization, one would learn that it took very little time to get an empire mad and fight for what they believed in, even with disease fluttering in the air, no weapons of destruction, or even horses to ride and attack the enemy with, the civilization was doomed to fail against the Europeans, and metaphorically speaking, Caliban’s people had no chance against the imperialistic Prospero.
