received the emirate of Mosul, including Jazirat Ibn ʿUmar, and Izz al-Dīn Abū Bakr al-Dubaysī was appointed as the city's governor. The city was transferred to Qutb al-Din Mawdud on his seizure of the emirate of Mosul after his elder brother Sayf al-Din's death in November 1149. 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. Sanjar Shah ruled until his murder by his son Ghazi in 1208, and was succeeded by his son Mu'izz al-Din Mahmud. Mahmud successfully maintained Zengid control over Jazirat Ibn ʿUmar with the marriage of his son Al-Malik al-Mas'ud Shahanshah to the daughter of Badr al-Din Lu'lu', who had overthrown the Zengids at Mosul, and usurped power for himself in 1233. The Grand Mosque of Jazirat Ibn ʿUmar was renovated during Mahmud's reign. In the early 13th century, the city's fort and madrasa are attested by Ibn al-Athir in Al-Tārīkh al-bāhir fī al-Dawlah al-Atābakīyah bi-al-Mawṣil, and its mosque by Ibn Khallikan in Wafayāt al-Aʿyān. According to the Arab scholar Izz al-Din ibn Shaddad, the Mongol Empire demanded 100,000 dinars in tribute from the ruler of Jazirat Ibn ʿUmar in 1251. The end of the Zengid dynasty was heralded by the death of Mahmud in 1251, as Badr al-Din Lu'lu' had Mahmud's successor Al-Malik al-Mas'ud Shahanshah killed soon after, and assumed control of Jazirat Ibn ʿUmar. Late medieval period Badr al-Din Lu'lu' acknowledged Mongol suzerainty to secure his realm as early as 1252, and minted coins in the name of Great Khan Möngke Khan in 1255 at the latest. He is also known to have had a mosque built at Jazirat Ibn ʿUmar. Badr al-Din became subject to the Mongol Ilkhanate on
