Which character best represents the colonized I'm the tempest

Around 1611, tells the story of power struggles on an almost deserted island. Prospero, the exiled Duke of Milan, has enslaved the only native of the isle, Caliban, and he plans and eventually manages to regain his dukedom through use of magic. Several of the characters vie for power in parallel plots. The play was written at a time when England was establishing itself as a colonial power along with other European empires such as Spain, Portugal, and France. The Tempest certainly deals with issues of colonialism in a topical way, especially through the character of Caliban, by alluding to physical and social otherness and financial incentives of colonialism. However, the ambiguous geographical setting together with Caliban’s sympathetic traits and his unresolved status at the end of the play invite the audience to question the legitimacy of power rather than endorsing or criticizing colonialism per se.
