Ibn ʿUmar was visited by the Moroccan scholar Ibn Battuta in 1327, and he noted the city's mosque, bazaar, and three gates. In 1326/1327, the city was granted as a fief to a Turkman chief, and Jazirat Ibn ʿUmar remained under his control until the disintegration of the Ilkhanate in 1335, soon after which it was seized by the Bohtan clan in 1336/1337 with the aid of al-Ashraf, Ayyubid Emir of Hisn Kayfa. In the 1330s, Hamdallah Mustawfi in Nuzhat Al Qulub reported that Jazirat Ibn ʿUmar had an annual revenue of 170,200 dinars. The emirate of Hisn Kayfa had aimed to control Jazirat Ibn ʿUmar through the Bohtan clan in providing military assistance to its capture and the marriage of a daughter to Izz ed-Din, Emir of Bohtan, but this was unsuccessful as the Bohtan emirate developed the city and consolidated their rule, and eventually the emir of Hisn Kayfa attempted to take Jazirat Ibn ʿUmar by force in 1384/1385, but was repelled. The emirate of Bohtan submitted to the Timurid Empire in 1400, after Timur sacked Jazirat Ibn ʿUmar in retribution for the emir having seized one of his baggage convoys. As punishment for the emir's refusal to participate in Timur's campaign in Iraq, the city was sacked by Timur's son Miran Shah. Early modern period Uzun Hasan usurped leadership of the Aq Qoyunlu from his elder brother Jahangir in a coup at Amid in 1452, and set about expanding his realm by seizing Jazirat Ibn ʿUmar in 1456, whilst the emir of Bohtan withdrew into the mountains. Rebellion and civil war followed the death of Uzun Hasan in 1478, and the emir of Bohtan retook Jazirat Ibn ʿUmar from the Aq Qoyunlu in 1495/1496. Jazirat Ibn ʿUmar came under Safavid suzerainty in the first decade of the 16th century, but after the Ottoman victory at the battle of Chaldiran over Shah Ismail I in 1514, Sultan Selim I sent Idris Bitlisi to the city and he successfully convinced the emir of Bohtan to submit to the Ottoman Empire. The emirate of Bohtan was incorporated into the empire as a hükûmet (autonomous territory), and was assigned to the eyalet (province) of Diyarbekir upon its formation in 1515. Sayyid Ahmad ruled in 1535. Christian families from Erbil found refuge and settled in Jazirat Ibn ʿUmar in 1566. In the mid-17th century, Evliya Çelebi visited Jazirat Ibn ʿUmar en route
