Origin and Service to King Vakhtang
Razhden was a Persian nobleman of Iranian descent; his name is traced to Iranian roots possibly meaning "happy religion." He served as guardian or tutor to Balendukht, a daughter of the Persian king, and accompanied her to Iberia upon her marriage to King Vakhtang I Gorgasali.
Having converted to Christianity in Kartli, he was granted an estate by the king and entered Vakhtang's military service as an adviser and commander. The sources present him as a distinguished warrior who proved his valor in the wars of the period.
