The Islamic State of Iraq and the Levant (ISIL, IPA /ˈaɪsəl/), alternatively translated the Islamic State of Iraq and Syria or Islamic State of Iraq and al-Sham (ISIS, /ˈaɪsɨs/), is a Salafi jihadist militant group that follows to an Islamic fundamentalist, Wahhabi doctrine of Sunni Islam. Derived from its Arabic name ad-Dawlah al-Islāmiyah fī ‘l-ʿIrāq wa-sh-Shām (الدولة الإسلامية في العراق والشام‎), the group is also known under the acronym Daesh (داعش‎ dāʿish, IPA: [ˈdaːʕiʃ]).
 
The group has referred to itself as the Islamic State (الدولة الإسلامية‎ ad-Dawlah al-Islāmiyah) or IS since it proclaimed a worldwide caliphate in June 2014 and named Abu Bakr al-Baghdadi as its caliph. As a caliphate, it claims religious, political and military authority over all Muslims worldwide. The group’s adoption of the name “Islamic State” and idea of a caliphate have been widely criticised, with the United Nations, various governments, and mainstream Muslim groups rejecting its statehood or caliphhood. As of December 2015, the group has control over vast landlocked territories in Iraq and Syria with population estimates ranging between 2.8 million and 8 million people, where it enforces Sharia law.

‘Y’all Qaeda’: People aren’t taking the armed militia in Oregon too seriously

What do you call cowboy hat-wearing militiamen who have taken over a federal building while criticizing the federal government with a deep southern drawl?
 
They might call themselves defenders of “the people.” But to most of Twitter, they’re “Y’all Qaeda,” “Vanilla ISIS,” “Yee Hawdists,” “Yokel Haram,” “Talibundy” and “Meal Team Six” — all plays on real-life jihadist terminology.
 
Social media exploded late Sunday night with widespread mockery of the armed group, which is led by Ammon Bundy, the flannel-cloaked 40-year-old son of rancher Cliven Bundy, who once sparred with the federal government over grazing rights — and won.
