9This book argues that the Arab Spring brought to the forefront numerous societal, political, and historical problems in the Middle East that scholars and practitioners throughout the 20th century and into the 21st century have continually glossed over or reduced in their analysis and analytical frameworks when studying the Middle East. These include the prevalent and persistent impact of Islam on political life, an impact of transnational and subnational identities, including sect, tribe, and regional identity, as well as the overuse of the state as the fundamental unit of analysis when studying the region. As a result, this book asserts that primordial identities including religion, sect, and tribe have, and will continue to have, a significant impact on the conduct of politics in the Middle East.
