Postcolonialism refers to the period after colonialism and postcolonial literature opposes colonialism. While it generally focuses on racism and its effects, the meaning of postcolonialism is debated. It influences theories around power, resistance, and identity and questions established concepts. An analysis of Jane Eyre that claims it promotes colonialism through Christian imagery and dichotomies of white/black is criticized for jumping to conclusions without considering alternate meanings of symbols like darkness.
