Islamic State in Iraq and Syria
Islamic State in Iraq and Syria (ISIS), a predominantly Sunni jihadist group, seeks to sow civil unrest in Iraq and the Levant with the aim of establishing a caliphate—a single, transnational Islamic state based on sharia. The group emerged in the ashes of the U.S.-led invasion to oust Saddam Hussein as al-Qaeda in Iraq (AQI), and the insurgency that followed provided it with fertile ground to wage a guerrilla war against coalition forces and their domestic allies.
After a U.S. counterterrorism campaign and Sunni efforts to maintain local security in what was known as the Tribal Awakening, AQI violence diminished from its peak in 2006–2007. But since the withdrawal of U.S. forces in late 2011, the group has increased attacks on mainly Shiite targets in what is seen as an attempt to reignite conflict between Iraq’s Sunni minority and the Shiite-dominated government of Prime Minister Nouri al-Maliki. Burgeoning violence in 2013 left nearly eight thousand civilians dead, making it Iraq’s bloodiest year since 2008, according to the United Nations. Meanwhile, in 2012 the group adopted its new moniker, ISIS (sometimes translated as Islamic State of Iraq and the Levant, or ISIL) as an expression of its broadened ambitions as its fighters have crossed into neighboring Syria to challenge both the Assad regime and secular and Islamist opposition groups there. By June 2014, the group’s fighters had routed the Iraqi military in the major cities of Fallujah and Mosul and established territorial control and administrative structures on both sides of the Iraqi-Syrian border.
