The twentieth-century African American women writers have not remained at the margins of the struggle for the true liberation of black people in the postcolonial and post-independence eras. They have used their novels as weapons to liberate their people from the postcolonial and post-independence nightmares prevailing within black communities. That is true of Zora Neale Hurston and Alice Walker. They have used their respective novels—Their Eyes Were Watching God (1937), The Third Life of Grange Copeland (1970), and Possessing the Secret of Joy (1992)—to help liberate black people from their different alienations following colonization and independence. However, these three novels have been perceived by some black critics as literary works reinforcing Blacks’ alienation and oppression. Contrary to this critical opinion, this article aims to reveal, through the postcolonial theory, that the two writers’ novels are truly works of liberation for black people from their political, cultural and social nightmares after colonization and independence. So, a deep inductive analysis of the three novels’ characters reveals that the novelists struggle against black leaders’ abuse of authority, Blacks’ deculturalization and fratricidal hatred in postcolonial and post-independence societies.
