On 12 October 2006, MSC united with three smaller groups and six Sunni tribes to form the Mutayibeen Coalition, pledging "To rid Sunnis from the oppression of the rejectionists (Shi'ite Muslims) and the crusader occupiers ... to restore rights even at the price of our own lives ... to make Allah's word supreme in the world, and to restore the glory of Islam".[18][19] A day later, MSC declared the establishment of the Islamic State of Iraq (ISI), comprising Iraq's six mostly Sunni Arab governorates,[20] with Abu Omar al-Baghdadi its emir[21][22] and al-Masri Minister of War within ISI's ten-member cabinet.[23]
