Levan was the eldest son of Heraclius II, then-king of Kakheti, by his third marriage to Darejan née Princess Dadiani, born in Tbilisi in 1756.

[2] The embassy ended in failure and the Georgian question was largely omitted in the Treaty of Küçük Kaynarca concluded between the Russian and Ottoman empires on 10 July 1774.

[4] Returning to Georgia, Levan was placed in 1774 by Heraclius II in charge of the newly created permanent frontier force (morige lashkari), whose statutes had been approved by the royal council on 4 January 1773.

[5] Levan's enthusiasm and personal courage helped make this force an effective instrument in fending off the incessant marauding inroads by the Dagestani mountaineers and won him a hero's status.

[1] The loss of his favorite son was a blow to the aging King Heraclius and the regular army which Levan had commanded gradually crumbled after his death.

As his sisterly nephew, Alexander Orbeliani, recalled in an 1865 essay on Levan, this princess was much loved by her husband, but regarded as frivolous and disliked by other members of the royal family.
