Gerges, Fawaz, ISIS, A History, Princeton University Press, 2016
The fall of Mosul to the Islamic State of Iraq and Syria (ISIS) in 2014 led to a wave of books attempting to explain the rise of the extremist group. ISIS, A History by London School of Economics International Relatives Professor Fawas Gerges is one of the better ones. He looks at four main factors to explain the emergence of ISIS: The fragmentation of the Iraqi state after the 2003 U.S. invasion, how ISIS grew out of Al Qaeda in Iraq, the Syrian Civil War and the 2011 Arab Spring. His thesis is that the organization created a revolutionary Salafi-Jihadist movement that played upon themes of Sunni victimization and which was opposed to the Shiite and Alawite dominated governments in Iraq and Syria.
