The present literary landscape in Nigeria is witnessing a firebrand engagement against an earlier tradition-centred cultural chauvinism, a bastion of which dominated and authenticated the purported order in society for a long time. Cultural conventions seem impenetrable but in continuous flow. No tidal waves of feminist gust seem to upturn the strongly held cultural conventions in favour of male gender. The human and social sense of justice and legitimate leadership is naturally vested on the male gender, who, in turn, allocates subservient duties to the female gender. The early works of Achebe particularly typify these cultural conventions in relation to gender constructions. A new horizon of re-negotiating historical conventions, dismantling the discursive limits, and examining Achebe’s earlier Igbo society against this postmodern literary discourse has however opened up vistas of previously unimaginable possibilities for the ‘new’ Igbo who are militantly introduced to feminist dissonances that seem to reverse the order in Achebe's literary experience This new sphere of literary existence is reflected in Chimamanda Adichie's works which outrightly rejects female gender conditioning which negatively hamper the aspirations of females and obstruct their visions in an unequal power and duty relations. The paper examines the parallels and divergences between Achebe and Adichie with the aim to unraveling the binary diffusions of cultural conventions and cultural dynamics in time frames.
