This book explores the public role of Islam in contemporary world politics. "Public Islam" refers to the diverse invocations and struggles over Islamic ideas and practices that increasingly influence the politics and social life of large parts of the globe. The contributors to this volume show how public Islam articulates competing notions and practices of the common good and a way of envisioning alternative political and religious ideas and realities, reconfiguring established boundaries of civil and social life. Drawing on examples from the late Ottoman Empire, Africa, South Asia, Iran, and the Arab Middle East, this volume facilitates understanding the multiple ways in which the public sphere, a key concept in social thought, can be made transculturally feasible by encompassing the evolution of non-Western societies in which religion plays a vital role.
