State. Abu Issa died in 2014, "after spending most of his final years in prison in London" Abu Umar al Kuwaiti became a judge for the Islamic state but was later executed for extremism after he "took takfir to new levels... pronouncing death sentences for apostasy on those who were ignorant of scripture – and then pronouncing takfir on those too reluctant to pronounce takfir." Islamic State (2014–present) The group Tanzim Qaidat al-Jihad fi Bilad al-Rafidayn (Al-Qaeda in Iraq) formed as an affiliate of Al-Qaeda network of Islamist militants during the Iraq War. The group eventually expanded into Syria and rose to prominence as the Islamic State of Iraq and the Levant (ISIL) during the Syrian Civil War. In the summer of 2014, the group launched the Northern Iraq offensive, seizing the city of Mosul. The group declared itself a caliphate under Abu Bakr al-Baghdadi on 29 June 2014 and renamed itself as the "Islamic State". ISIL's claim to be the highest authority of Muslims has been widely rejected. No prominent Muslim scholar has supported its declaration of caliphate; even Salafi-jihadist preachers accused the group of engaging in political showmanship and bringing disrepute to the notion of Islamic state. ISIL has been at war with armed forces including the Iraqi Army, the Syrian Army, the Free Syrian Army, Al-Nusra Front, Syrian Democratic Forces, and Iraqi Kurdistan's Peshmerga and People's Protection Units (YPG) along with a 60 nation coalition in its efforts to establish a de facto state on Iraqi and Syrian territory. At its height in 2014, the Islamic State held "about a third of Syria and 40 percent of Iraq". By December 2017 it had lost 95% of that territory, including Mosul, Iraq's second largest city, and the northern Syrian city of Raqqa, its "capital". It's caliph, Al-Baghdadi, was killed in a raid by U.S. forces on 26 October 2019, its "last holdout", the town of Al-Baghuz Fawqani, fell to Syrian Democratic Forces on 23 March 2019. Ahmadiyya view The members of the Ahmadiyya community believe that the Ahmadiyya Caliphate (Arabic: Khilāfah) is the continuation of the Islamic caliphate, first being the Rāshidūn (rightly guided) Caliphate (of Righteous Caliphs). This is believed to have been suspended with Ali, the son-in-law of Muhammad and re-established with the appearance of Mirza Ghulam Ahmad (1835–1908, the founder of the movement) whom Ahmadis identify as the Promised Messiah and Mahdi. Ahmadis maintain that
