On 29 June 2014, ISIS announced the establishment of a caliphate, al-Baghdadi was named its caliph, to be known as Caliph Ibrahim, and the Islamic State of Iraq and the Levant was renamed the Islamic State. There has been much debate across the Muslim world about the legitimacy of these moves.
The declaration of a caliphate has been heavily criticized by Middle Eastern governments and other jihadist groups, and by Sunni Muslim theologians and historians. Yusuf al-Qaradawi, a prominent scholar living in Qatar stated: “[The] declaration issued by the Islamic State is void under sharia and has dangerous consequences for the Sunnis in Iraq and for the revolt in Syria”, adding that the title of caliph can “only be given by the entire Muslim nation”, not by a single group.
On 2 July 2014, al-Baghdadi announced that ISIS would march on Rome in its quest to establish an Islamic State from the Middle East across Europe, saying that he would conquer both Rome and Spain in this endeavor.
