Islamic State & Predecessor Groups
This is the gateway to resources, research, and analysis the Combating Terrorism Center has produced over the last decade about the Islamic State, also referred to as the Islamic State of Iraq and al Sham (ISIS) and Da`ish, and its predecessor groups (al-Tawhid wa-al-Jihad, al-Qa`ida in Mesopotamia (AQI), Majlis Shura al-Mujahidin, Hilf al-Muttayibin and the Islamic State of Iraq (ISI)).
Additional CTC research and analysis about factors shaping the conflict in Iraq and Syria is also included. These resources contextualize the development of the Islamic State. Resources are organized into five categories: major reports, CTC Sentinel articles, CTC Perspectives, CTC commentary about the early development of AQI, and declassified primary sources produced by AQI, ISI, and other militant groups in Iraq.
