Establishment of the Iranian church thumb|alt=Persian miniature of Yazdegerd I and his son Bahram (later known as Bahram V)|16th-century Shahnameh illustration of Yazdegerd I and his son, the future Bahram V Yazdegerd I's reign was a landmark for the Christians in Iran. With the counsel of Roman bishop Marutha, he acknowledged the Church of the East in 410; this led to the establishment of the Iranian church, which would declare its independence from the Roman church in 424. Yazdegerd's decree has been called the Sasanian version of the 313 Edict of Milan by Roman emperor Constantine the Great (). Churches, shrines to martyrs, and monasteries were soon established under Iranian bureaucracy. They were near the court in the Sasanian capital of Ctesiphon, indicating the consent of Yazdegerd (who financed churches with East Syrian or Roman diplomats as their main patrons). One of his gestures of generosity was to permit Christians to bury their dead, which Zoroastrians believed tainted the land.
