“Mamdani takes the case of Sudan to demonstrate how colonial law established tribal identity as the basis for determining access to land and political power, and follows this law’s legacy to contemporary Darfur. He considers the intellectual and political dimensions of African movements toward decolonization by focusing on two key figures: the Nigerian historian Yusuf Bala Usman, who argued for an alternative to colonial historiography, and Tanzania’s first president, Mwalimu Julius Nyerere, who realized that colonialism’s political logic was legal and administrative, not military, and could be dismantled through nonviolent reforms” – http://www.hup.harvard.edu/catalog.php?isbn=9780674050525
