Khosrov IV

[3] Ferdinand Justi,[4] Cyril Toumanoff[5] and Christian Settipani assume that Khosrov was the son of the earlier Armenian king Varazdat.

In 387, the partition was formalized with the Peace of Acilisene (Ekeghiats), with the new border running north to south from a point east of Karin (modern Erzurum) to Mesopotamia west of Nisibis.

Khosrov IV kept the Arsacid capitals of Artashat and Dvin in his kingdom, while Arshak ruled in Roman-controlled Ekeghiats until his death c. 390.

[11] The Sasanian king Shapur III gave his sister Zruandukht as wife to Khosrov IV, as well as a large army to protect Armenia and a tutor from the House of Zik.

[13] According to Khorenatsi, this occurred after Catholicos Sahak visited the court of the Sasanian king Yazdegerd I to request Khosrov's release.
