International Relations as a discipline has long privileged Eurocentric and masculinist frameworks that obscure the historical and contemporary contributionsof African women. This paper interrogates those exclusions through the lens of Postcolonial Feminist Theory, repositioning African women not as peripheral figures but as central agents in global political life. It traces their roles across precolonial governance systems, anti-colonial struggles, liberation wars, and contemporary peacebuilding, showing how their practices of resistance, care, and leadership unsettle dominant paradigms of power, security, and agency. Methodologically, the study employs a qualitative interpretivist approach grounded in textual analysis and African feminist scholarship, enabling a reconstruction of marginalized voices, indigenous epistemologies, and suppressed histories. The analysis demonstrates that reclaiming African women’s agency is not about assimilation into existing frameworks but about transforming the logics that render them invisible and subordinate. African feminist thought thus offers alternative imaginaries of politics rooted in relationality, communal resilience, restorative justice, and epistemic justice. By centering these perspectives, the paper contributes to rethinking IR beyond its colonial legacies and toward a more inclusive, ethical, and sustainable discipline. The findings affirm that any genuine project of global transformation must take seriously African women’s voices as vital sites of knowledge, resistance, and power.
