Islamic State

The Islamic State (IS), also known as the Islamic State of Iraq and the Levant (ISIL), the Islamic State of Iraq and Syria (ISIS) and by its Arabic acronym Daesh, is a transnational Salafi jihadist group and a former unrecognised quasi-state. Its origins were in the Jai'sh al-Taifa al-Mansurah organization founded by Abu Omar al-Baghdadi in 2004, which fought alongside al-Qaeda during the Iraqi insurgency. The group gained global prominence in 2014, when its militants successfully captured large territories in northwestern Iraq and eastern Syria, taking advantage of the ongoing Syrian civil war. By the end of 2015, it ruled an area with an estimated population of twelve million people, where it enforced its extremist interpretation of Islamic law, managed an annual budget exceeding US$1 billion, and commanded more than 30,000 fighters.
After a protracted and intense conflict with American, Iraqi, and Kurdish forces, IS lost control of all its Middle Eastern territories by 2019. It subsequently reverted to insurgency tactics, operating from remote hideouts while continuing its propaganda efforts. These efforts have garnered it a significant following in northern and Sahelian Africa.
Between 2004 and 2013, IS was allied to al-Qaeda (primarily under the name "Islamic State of Iraq") and participated in the Iraqi insurgency against the American occupation. The group later changed its name to "Islamic State of Iraq and Levant" for about a year, before declaring itself to be a worldwide caliphate, called simply the Islamic State (الدولة الإسلامية, ad-Dawlah al-Islāmiyah). As a self-proclaimed caliphate, it demanded the religious, political, and military obedience of Muslims worldwide, despite the rejection of its legitimacy by mainstream Muslims and its statehood by the United Nations and most governments.
