Yazdegerd I
Yazdegerd I, also spelled Yazdgerd I and
Yazdgird I
(New Persian:), was Sasanian King of Kings of Iran from 399 to 420.
A son of Shapur III , he succeeded his brother Bahram IV  after Bahram's assassination.
Yazdegerd
I's
largely-uneventful reign is seen in Sasanian history as a period of renewal.
Although he was periodically known as "the Sinner" in native sources, Yazdegerd was more competent than his recent predecessors.
He enjoyed cordial relations with the Eastern Roman Empire and was entrusted with the guardianship of the Roman prince, Theodosius, by Theodosius' father Arcadius.
Yazdegerd I is known for his friendly relations with the Jews and Christians of the Church of the East, which he acknowledged in 410.
Because of this, he was praised by Jews and Christians as the new Cyrus the Great (king of the Iranian Achaemenid Empire who liberated the Jews from captivity in Babylon).
The king's religious, peaceful policies were disliked by the nobility and Zoroastrian clergy, whose power and influence he strove to curb.
This eventually backfired, and Yazdegerd I met his end at the hands of the nobility in the remote northeast.
The nobles then sought to stop Yazdegerd's sons from the ascending the throne; his eldest son, Shapur IV, was quickly killed after his accession and replaced with Khosrow.
Another son, Bahram V, hurried to the Sasanian capital of Ctesiphon with an Arab army and pressured the nobility to acknowledge him as shah.
