 Mufarrij was also the preeminent chieftain of the Banu Tayy tribe as a whole, giving him authority over his Bedouin and peasant kinsmen in an area extending from the coast of Palestine eastward through Balqa and to the Tayy's traditional homeland in northern Arabia.While his Fatimid assignment gave him prestige, Mufarrij's tribal authority was the source of his independent power.The Tayyid-dominated region was the location of the overland routes connecting Egypt, Syria, Iraq and Arabia.
