The secession of South Sudan in July 2011 took place against the backdrop of the Arab Spring, spurring hopes of a "new beginning" that might lead to a more just, democratic Sudan. Nonetheless, the years following secession have witnessed new wars, growing unrest, and renewed calls for the removal of the Islamist regime in Khartoum. This book examines how the Islamist project has shaped developments in Sudan, with a particular focus on how divisive policies at the local and regional levels have created growing regional subcultures of ethnic violence and fragmentation - as well as renewed struggles to fight continued marginalization.
