the alliance, Bagrat's daughter Mart’a (Maria) married, at some point between 1066 and 1071, the Byzantine co-emperor Michael VII Ducas. The choice of a Georgian princess was unprecedented, and it was seen in Georgia as a diplomatic success on Bagrat's side. On 10 December 1068, Alp Arslan accompanied by the kings of Lorri and Kakheti as well as the emir of Tbilisi again marched against Bagrat. The provinces of Kartli and Argveti were occupied and pillaged. Bagrat's long-time rivals, the Shaddadids of Arran, were given compensation: the fortresses of Tbilisi and Rustavi. After Alp Arslan left Georgia, Bagrat recovered Kartli in July 1068. Al-Fadl I b. Muhammad, of the Shaddadids, encamped at Isani (a suburb of Tbilisi on the left bank of the Mtkvari) and with 33,000 men ravaged the countryside. Bagrat defeated him, however, and forced the Shaddadid troops to flight. On the road through Kakheti, Fadl was taken prisoner by the local ruler Aghsartan. At the price of conceding several fortresses on the Iori River, Bagrat ransomed Fadl and received from him the surrender of Tbilisi where he reinstated a local emir on the terms of vassalage. The last years of Bagrat's reign coincided with what Professor David Marshall Lang described as "the final débacle of eastern Christendom" — the Battle of Manzikert — in which Alp Arslan dealt a crushing defeat to the Byzantine army, capturing the emperor Romanos IV, who soon died in misery. Bagrat IV died the following year, on 24 November 1072, and was buried at the Chkondidi Monastery. The suzerainty over the troubled kingdom of Georgia passed to his son George II.
