Aswagen was the eight Arsacid king of Caucasian Albania, ruling from approximately 415 to 440. He was most likely the son of the previous Albanian king Urnayr, while his mother was a daughter of the Sasanian King of Kings (shahanshah) of Iran, Shapur II. Aswagen was himself married to a daughter of shahanshah Yazdegerd II. It was under Aswagen that the Caucasian Albanian script was created in c. 420.
