To cite this publication: “Sectarian Politics in the Gulf,” CIRS Summary Report no. 7 (Doha, Qatar: Center for International and Regional Studies, 2012).This Summary Report contains synopses of chapters written for the “Sectarian Politics in the Gulf” research initiative over two working group meetings that took place in Doha. The central aim of this study is to examine the dynamic ways in which evolving sectarian identities and politics in the Gulf region intersect. Encompassing Iran and the states of the Arabian Peninsula, the research project includes topics that focus on how sectarian issues play out in the realms of domestic politics within Gulf states, as well as those that address sectarianism’s impact on inter-state relations within the region. This project brings together a renowned group of scholars to examine the issues of religious, communal, and ethnic identities in the Gulf, and how these impose themselves on both the domestic and international politics of the Gulf. The volume is titled, Sectarian Politics in the Persian Gulf (Oxford University Press, 2015), edited by Lawrence G. Potter.
