On 29 June 2014, ISIL proclaimed itself to be a worldwide caliphate.[78] Abu Bakr al-Baghdadi – known by his supporters as Amir al-Mu'minin, Caliph Ibrahim – was named its caliph, and the group renamed itself ad-Dawlah al-Islāmiyah ("Islamic State" (IS)).[79] As a "Caliphate", it claims religious, political and military authority over all Muslims worldwide.[80] The concept of it being a caliphate and the name "Islamic State" have been rejected by governments and Muslim leaders worldwide.[81][82][83][84][85][86][87]
