This is answer is geared towards contemporary literature, where women are still largely relegated to a lesser role in the writings of many notable African authors. During Colonialism, women played very docile, gentle, and feeble roles of house maids, teachers, and burdens to their families. These roles haven't changed much with the times. Despite the rise in Feminism across the world, African literature continues to marginalized the roles of women.
Some African authors insist that they are writing stories that explain the plight of the African woman, but research and literary analysis have shown that this is not the case. In fact, male dominance is promulgated through literature, as literature is largely used to tell a one-sided view of the African experience. After all, many of the authors who are promoting patriarchy benefit more from its promotion.
