Even today, slavery remains paramount in African American culture. The barbarous practice of human bondage was not unique to America, but in the American South slavery became based exclusively on race. The centuries of servitude endured by Africans shaped their writing, music, and customs — oppression became the most definitive aspect of their culture. Among the truly remarkable accomplishments in American history was the creation of a uniquely African American culture amidst a United States political system hell bent on denying Africans the conditions required for developing that culture. This culture reverberates through the centuries via the powerful literature of the oppressed.
