This paper conducts a comparative case study of how gender discourse in Igbo society has evolved from pre-colonial, colonial to post-colonial periods, more so, how this evolution contributes to the debate on cultural imperialism. It claims that an historical understanding of gender relations in Igbo society could provides an understanding of national cultural imperialism from a political perspective. With the assumptions of cultural imperialism, it reviews how the effect of colonialism contributes to the evolution of gender discourse in Igbo society. According to some earlier researches, gender equality in Igbo society has been on a constant slide from what was obtainable in the pre-colonial era. This trend as it is analyzed, collaborates the assumptions of national cultural imperialism; thereby disentangling the congested concept of cultural imperialism.
