Burhan Ghalioun's seminal work critically examines the evolution and deep-seated persistence of sectarianism within Arab societies. The book traces a significant shift from a state-controlled sectarian apparatus to an increasingly fragmented, tribally or sub-state defined identity. Ghalioun meticulously dissects the mechanisms through which sectarian divisions are historically manipulated by political elites, thereby hindering genuine national unity and sustainable development. Offering a profound and incisive analysis, the author explores the multifaceted historical and contemporary factors that perpetuate this complex phenomenon, shedding light on its devastating impact on governance, social cohesion, and the future trajectory of the region. This book is an essential read for anyone seeking to understand the intricate dynamics of identity politics in the Middle East, challenging prevailing narratives and advocating for more inclusive societal frameworks beyond sectarian allegiances.
