The Grand Mosque of Jazirat Ibn ʿUmar was constructed in 1155. After Qutb al-Din's death in September 1170, Jazirat Ibn ʿUmar was inherited by his son and successor Sayf al-Din Ghazi II as emir of Mosul. Michael the Syrian recorded that a Syriac Orthodox monastery was confiscated and the city's bishop Basilius was imprisoned in 1173. Upon the death of Sayf al-Din Ghazi in 1180, Jazirat Ibn ʿUmar was granted as an iqta' to his son Mu'izz al-Din Sanjar Shah within the emirate of Mosul, however, in late 1183, Sanjar Shah recognised Saladin as his suzerain, thus becoming a vassal of the Ayyubid Sultanate of Egypt, and effectively forming an autonomous principality. Sanjar Shah continued to mint coins in his own name, and copper dirhams were minted at Jazirat Ibn ʿUmar in 1203/1204.
