This study explores the relationship between defiance and desire in Oroonoko, placing the work within a postcolonial framework to reveal its revolutionary qualities. Through the portrayal of Oroonoko as a noble yet tragic figure, Aphra Behn exposes the power structures of colonialism while highlighting the complex hopes and struggles of her characters. The analysis focuses on themes of agency, resistance, and identity conflict in a colonized world, suggesting that Behn’s narrative extends beyond its historical setting to resonate with modern discussions of racism and imperialism. The paper argues that Oroonoko not only reflects the tensions of its time but also stands as a powerful testament to the resilience of the human spirit in the face of injustice. It examines the interaction between love and betrayal, showing how personal relationships are shaped by broader social and political forces. Oroonoko’s tragic fate becomes a sharp critique of the commodification of human life under colonial rule. Attention is also given to Behn’s language and narrative style, demonstrating how her stylistic choices deepen both the emotional and political impact of the story. The relationship between Oroonoko and Imoinda illustrates how love can function simultaneously as a form of resistance and a site of power struggle. The study, then considers Behn’s role as a female writer within a male-dominated literary tradition, arguing that her perspective enriches postcolonial discussions by foregrounding marginalized voices and challenging dominant narratives of authority and empire.
