Book excerpt: For most of its history, the African continent has witnessed momentous political change, remarkable philosophical innovation, and the complex cross-fertilization of ideologies and belief systems. This definitive study surveys the concepts, values, and historical upheavals that have shaped African political systems from the ancient period to the postcolonial era and beyond. Beginning with the emergence of indigenous political institutions, it traces the most important developments in African history, including the Africanization of Islam, liberal democratic movements, socialism, Pan-Africanism, and Africanist-Populist resistance to the neoliberal world order. The result is an invaluable resource on a region too often ignored in the history of political thought.
