Картлис цховреба
Liparit appeared on the political scene of Georgia in the late 1020s when he, as a holder of the fortress of Kldekari and later as a commander-in-chief of the royal armies, proved himself as the defender of the boy king Bagrat IV and his regent Dowager Queen Mariam. The Georgian Chronicles identify Liparit as "the son of Liparit", while John Skylitzes refers to him as son of ‘Оράτιης Λιπαρίτης, i.e., Rati. His successful resistance to the invading Byzantine troops in 1028 and a victorious campaign against the Shaddadid dynasty of Arran in 1034 made Liparit the most powerful noble in Georgia. In 1038 Liparit was on the verge of capturing the Georgian city of Tbilisi, which had been under the Muslim sway for centuries; but fearing his growing power the Georgian nobles thwarted the plan and persuaded the king to make peace with the emir of Tbilisi. As a result, Liparit turned into a sworn enemy of Bagrat and began actively cooperating with foreign powers for vengeance. In 1039, he pledged his support to Bagrat’s half-brother Demetrius who entered Georgia with a Byzantine army to seize the crown. After Demetrius’ death in 1042, Liparit continued the struggle against Bagrat and became a major champion of the Byzantine influence in the region. He enjoyed numerous successes against the royal armies, most notably at Sasireti, where Bagrat suffered a crushing defeat and was forced to withdraw from his eastern possessions. The battle is also known for the involvement of Varangian mercenaries, most probably on the king’s side.
