The conclusion synthesizes and reflects upon the case studies and comparative and theoretical contributions in the book. The cases are organized around three categories: first, relatively conventional decentralization initiatives in which reforms were adopted to improve governance; second, contexts in which decentralization has been contemplated as a framework for self-determination for the region’s stateless communities; and finally, decentralization initiatives undertaken in the shadow of conflict and state fragmentation. This concluding chapter develops theoretical insights drawn from the rich terrain for qualitative comparison across these three contexts. It offers reflections on key characteristics of the shared regional context and a typology of factors driving decentralization in the Middle East and North Africa (MENA) region. It argues that an important contribution of the volume lies in identifying a broader array of motivations for, and actors driving, decentralization than currently reflected in the scholarly literature and in parsing the implications for the institutional design of decentralized government. The chapter concludes by distilling patterns from the cases to identify distinct trajectories of decentralization that are evidenced in the MENA region and their entailments.
