ISIL is known for its extensive and effective use of propaganda.[1] It uses a version of the Muslim Black Standard flag and developed an emblem which has clear symbolic meaning in the Muslim world.[2]
Videos by ISIL are commonly accompanied by nasheeds (chants), notable examples being the chant Dawlat al-Islam Qamat, which came to be viewed as an unofficial anthem of ISIL,[3] and Salil al-sawarim.[4]
