Mufarrij ibn Daghfal ibn al-Jarrah al-Tayyi (fl. ca. 977–1013), in some sources erroneously called Daghfal ibn Mufarrij, was an emir of the Jarrahid family and leader of the Tayy tribe. Mufarrij was engaged in repeated rebellions against the Fatimid Caliphate, which controlled southern Syria at the time. Although he was several times defeated and forced into exile, by the 990s Mufarrij managed to establish himself and his tribe as the de facto autonomous masters of much of Palestine around Ramlah (the district of Jund Filastin) with Fatimid acquiescence. In 1011, another rebellion against Fatimid authority was more successful, and a short-lived Jarrahid-led Bedouin state was established in Palestine centred at Ramlah. The Bedouin even proclaimed a rival Caliph to the Fatimid al-Hakim, in the person of the Alid Abu'l-Futuh al-Hasan ibn Ja'far. Bedouin independence survived until 1013, when the Fatimids launched their counterattack. Their will to resist weakened by Fatimid bribes, the Bedouin were quickly defeated. At the same time Mufarrij died, possibly poisoned, and his sons quickly came to terms with the Fatimids. Among them, Hassan ibn Mufarrij al-Jarrah managed to succeed to his father's position, and became a major player in the politics of the region over the next decades.
