He performed in the court of Heraclius II of Georgia, where he also worked as a diplomat, and apparently helped forge an alliance between Georgia, Armenia and Shirvan against the Persian Empire. He lost his place at court when he fell in love with the king's daughter, and spent the rest of his life as an itinerant bard. In 1795 he was killed in Haghpat Monastery by the army of Agha Mohammed Khan. Read further on Wikipedia here

Who was Erekle II ?

In 1795, he demanded that Erekle acknowledged Persian suzerainty, promising in return to confirm him as wali. Erekle refused, and in September 1795, the Persian army of 35,000 moved into Georgia. After the valiant defense of Tbilisi at the Battle of Krtsanisi, Erekle’s small army was almost completely annihilated, with the king becoming a witness of the fearful devastation of his capital and being forced to retreat into the mountains. The Persian invasion delivered a hard blow to Georgia from which it was not able to recover. Despite being abandoned at the critical moment, he still had to rely on the Russian belated support and fought, in 1796, alongside the Russian expeditionary forces sent by Catherine into the Persian possessions. But her death that year brought an abrupt change of policy in the Caucasus, and her successor Paul I withdrew all Russia troops from the region. Aga Mohammad launched his second campaign to punish the Georgians for their alliance with Russia. However, his assassination in 1797 spared Kartli-Kakheti more devastation.
