Artasires or Artasires Artaxias
the last Arsacid on the throne of Armenia, the son of Bahram Shapur, and the nephew of Chosroes. Moses Chorenensis tells us, that his real name was Ardashes. (Artases or Artaxes.)
He was made king of Armenia in 422, by Bahram IV., who ordered or requested him to adopt the name of Ardashir (Artasires or Artaxerxes). As Artasires was addicted to vices of every description, the people, or rather the nobles of Armenia, wished for another king.
Since the conversion of prince Gregory (afterwards St. Gregory), the son of Anag, the Arsacid, to the Christian religion, in the time of Constantine the Great, the Armenians had gradually adopted the Christian religion; and there was a law that the patriarch should always be a member of the royal family of the Arsacidae. During the reign of Artasires the office of patriarch was held by Isaac, to whom the nobles applied when they wished to choose another king; but Isaac aware that their choice would fall upon Bahram, the heathen king of Persia, refused to assist them.
The nobles thereupon applied straightway to Bahram, who invaded Armenia, deposed Artasires, and united his dominions to Persia, A. D. 428.
