The Life of Kings, written c. 800, identifies Saurmag as the son and successor of Parnavaz, the founder of the Parnavaziani dynasty, and establishes a pattern of succession based upon primogeniture.
Learning of the plot, Saurmag took refuge in the land of Dzurdzuks (ancestors of modern-day Vainakhs), a country of his mother’s origin.
With the Dzurdzuk help, Saurmag quashed a revolt, and went on to create a new class of nobles directly dependent on the crown.
[1] The chronicle also states that Saurmag remained adherent to the pro-Seleucid policy adopted by his father.
[3] He is reported to have died without a male heir, and succeeded by his adopted son and son-in-law Mirian.
