Post-colonial criticism is similar to New Historicism, but it has a unique focus: the power struggle between the colonists and the colonized. Post-colonial theory examines works produced by colonial powers and/or colonized peoples, looking at the interplay of power, economics, politics, religion, and culture within a colonialist structure. Post-colonialism often fights back against Eurocentrism (the focus on European, often white, peoples) by giving a voice to the marginalized peoples whose stories have been historically omitted. This extends to critiquing works' canonical status, as most of those works are written by white men. On occasion, post-colonial critics will write a retelling/critique of a work in order to bring into focus the colonial attitudes within it. This is the case of Jean Rhys's Wide Sargasso Sea, which tells the story of the marginalized first wife from Jane Eyre, brings into relief issues of race and power that the original work glosses over.
