Arsaces (son of Khosrov IV of Armenia)

Arsaces (Արշակ) was an Armenian Prince of the Arsacid dynasty of Armenia who lived in the second half of the 4th century and possibly first half of the 5th century.

According to modern genealogies, Arsaces was a son born to the Armenian Monarchs Khosrov IV and Zruanduxt, while his brother was Tigranes. The father of Arsaces, Khosrov IV was an Arsacid Prince who was the first Armenian Monarch to serve as a Client King of Eastern Armenia under Sassanid rule who reigned from 387 until 389. His mother Zruanduxt, was a Sassanid Princess from Persia who was the sister of the Sassanid King Shapur III who reigned from 383 until 388.

Arsaces was named in honor of his late relative Arsaces III (Arshak III), the last serving Roman Client King of Armenia. He was also named in honor of his Parthian, Pontian and Armenian ancestors who ruled with this name as King. He was born at an unknown date in his father’s kingship and raised in Eastern Armenia. It is unknown whether he became a Christian in faith or a follower of the religion of Zoroastrianism.

In 389 the Sassanid King Bahram IV, dethroned Khosrov IV and placed him in confinement in Ctesiphon. Bahram IV was unsatisfied with Khosrov IV. Bahram IV considered Khosrov IV, as being too assertive in his royal authority as a governing Client Monarch and did various acts in his kingship without consultation from the Sassanid dynasty. Bahram IV in 389 replaced Khosrov IV, with his brother Vramshapuh as Sassanid Client King of Arsacid Armenia. After this moment, the fate of Zruanduxt, Arsaces and Tigranes is unknown.
