Toni Morrison and Octavia Butler are two representative figures in the African American literary world; both have made great contributions to American Literature by revealing the reality of black women’s lives. They are all sensitive to black women’s living conditions and write to show their sufferings, struggles and rebellions in a white- and male-dominant society. Morrison’s Home and Butler’s Kindred are set in the 1810s, 1950s and 1970s’ America and uncover black women’s experiences in these three periods. Their heroines are harmed both physically and psychologically by the society’s exercise of power. This thesis, drawing upon black feminism and Foucault’s power theory, demonstrates the society’s oppression of black women to uncover the reality of their existence; and traces how black women strive to change power in different historical times. The main body of the thesis consists of three parts: Chapter Two analyzes the American society’s oppression of black women with its exercise of different power mechanisms in different periods. Chapter Three explores the recreating of home in Home and Kindred. Chapter Four demonstrates black women’s struggle for changing power through unceasing rebellion attempts. Along the process, the thesis also touches on the relational change between the white and black, male and female. Exploring the questions of antebellum slavery and recent history, the thesis draws the conclusion that the society’s constant exercise of power is the fundamental cause for black women’s centuries-long suffering; but black women are making progresses in reclaiming for their equal rights. The thesis also suggests that the American society can be cured through integration and coalition across the boundaries of different races and genders.
