Through his father, Khosrov I was a member of the House of Parthia and thus a relation of the Arsacid dynasty of Armenia.
[7] The modern historian Lee E. Patterson suggests that Agathangelos may have exaggerated the importance of his homeland.
[11] As a client monarch of Rome, Khosrov I was under the protection of Septimius Severus and his successor Caracalla.
[12] Between 214 and 216, Khosrov I with his family were held under Roman detention for unknown reasons which provoked a major uprising in Armenia against Rome.
[15] In 217 when Khosrov I died, his son Tiridates II,[16] was granted the Armenian crown[17] by the Roman emperor Caracalla.
