This paper investigates acclaimed Nigerian Author Flora Nwapa's nuanced literary portrayals of the challenges Nigerian women face within marital roles and relationships. Through textual analysis of characters and events across Nwapa's novels, short stories and folklore centered on women's experiences, the study illuminates critical perspectives on issues of patriarchy, lack of autonomy, rigid gender roles, and socioeconomic restrictions undermining women’s agency and fulfillment. Core themes highlighted in Nwapa's subtle social commentary include anguish over infertility, hardships from prolonged spousal absence, emotional tolls of polygamy, lack of personal choice in partners, limited educational and career opportunities, economic dependence, and domestic violence. Her visionary work gives voice to Nigerian women’s aspirations while exposing oppressive structures. Findings substantiate how Nwapa’s rich depictions of women navigating complex marital terrain reveal an array of postcolonial and patriarchal impediments to female empowerment. Her literary portrayal of restrictions, conflicts and oppression compels critical examination of norms inhibiting women’s advancement. By confronting gender-based inequities and envisioning transformative possibilities, Nwapa leads African women writers in catalyzing legal and sociocultural reforms to promote women’s full flourishing.
