This book offers a systematic examination of the politics of Middle Eastern cities in a broad historical and comparative context. Focusing on the contribution of informal networks, the author examines four types. He reveals that, contrary to recent claims, informal associations do not necessarily play a stabilizing role in urban politics, but reveal themselves to be effective instruments for mobilizing popular dissent. Denoeux identifies conditions under which these informal urban networks can change their role from system-supportive to system-challenging. His analysis highlights the impact of Islam on contemporary forms of urban violence in the Middle East, and emphasizes the destabilizing potential for the urban poor. His approach sheds new light on the politics of Islamic fundamentalism and on the nature of urban unrest in a vital yet neglected region of the world and represents a very significant contribution to an emerging literature on informal political processes.
