In 378 with the failed reign of Varasdates and the murder of Mushegh Mamikonian, the latter's brother,
Manuel Mamikonian, filled the position of
sparapet. Furious at the king, Manuel drove out Varasdates from Armenia back to Rome. Manuel raised Arsaces III and Vologases to the throne as co-kings of Armenia, under the nominal regency of their mother Zarmandukht. To end the political anarchy in the country as Manuel being now the powerful regent-in-charge of Armenia, Manuel married Arsaces III to his daughter
Vardandukht and he married Vologases to the daughter of Sahak from the
Bagratuni dynasty. The Mamikonian government brought peace, stability to Armenia in which Manuel guided the country wisely. Manuel treated Arsaces III, Vologases and Zarmandukht with honor. He raised Arsaces III and Vologases and Manuel nurtured them as if they were his own children. Vologases with his brother, aggressively pursued a policy on
Christian Arianism. Vologases was the only King of Armenia to rule with this name, who wasn't at the same time, also serving as King of
Parthia. Despite Armenia being the first Christian state, there were still traces of beliefs and customs in
Zoroastrianism, sun worship and practices of consanguineous marriages in the country. An example of this was at Bagawan, where there was a fire temple set up and the destruction of statues placed there by Vologases. The zeal of the
Sassanid high priest
Kartir established and fostered fire temples, especially in Armenia which was attested by his inscriptions. As Vologases died in 386 without leaving an heir and Manuel Mamikonian died at the same time as him, Arsaces III became the sole-ruler of Armenia. ==References==
