lands. The Emirate of Tbilisi grew in relative strength under Ishaq ibn Isma'il (833–853), who was powerful enough to quell the energies of the Georgian princes and to contend with the Abbasid authority in the region. He withheld his annual payment of tribute to Baghdad, and declared his independence from the Caliph. To suppress the rebellion, in 853 Caliph al-Mutawakkil dispatched a punitive expedition led by Bugha al-Kabir (also known as Bugha the Turk) who burned Tbilisi to the ground and had Ishaq decapitated, putting an end to the city's chance to become the center of an independent Islamic state in the Caucasus. The Abbasids chose not to rebuild the city extensively, and as a result the Muslim prestige and authority in the region began to wane. Beginning in the 1020s, the Georgian kings pursued a contradictory but generally expansionist policy against the emirs of Tbilisi, this latter coming sporadically under Georgian control. The territories of the emirate shrank to Tbilisi and its immediate environs. However, the Seljuk invasions of the 1070s–1080s thwarted the Georgian advance and deferred the Bagratid plans for nearly a half of a century. The last line of emirs of Tbilisi ended, presumably, circa 1080, and the city was run thereafter by the merchant oligarchy known in the Georgian annals as tbileli berebi, that is, the elders of Tbilisi. Georgian King David IV’s victories over the Seljuk Turks inflicted a final blow to Islamic Tbilisi, and a Georgian army entered the city in 1122, ending four hundred years of Muslim rule. Legacy The office of emir — amira or amirtamira — now an appointed Georgian royal official — survived in Tbilisi, as well as other big cities of Georgia, into the 18th century, being substituted by the office of mouravi.
