About Yezdagird III, Shah of Persia

Ruled 632-651; Arab Conquest, end of Sasanian Empire.


Yazdgerd III (also spelled Yazdegerd or Yazdiger, Persian: یزدگرد سوم, "made by God") was the twenty-ninth and last king of the Sassanid dynasty of Iran and a great-grandson of our ancestor King Khosro II (590–628), who had been murdered by his son (Yazdgard's grandfather, our ancestor) King Kavadh II of Persia in 628. Yazdgerd III ascended the throne on June 16, 632 after a series of internal conflicts.

Yazdgerd III reigned as a youth and never truly exercised authority. In his first year the Arab invasion of Iran began, and in 636 the Battle of al-Qādisiyyah decided the fate of the Persian empire. To gain some modest supports from the Persian Empire's old rival, the Roman Empire of the East, he sought an alliance with the Emperor Heraclius who then married off his young granddaughter, Manyanh, the daughter of Heraclius Constantine III and Princess Gregoria of Persia. Yazdgerd and Manyanh had issue.

Following the battle of al-Qādisiyyah the Caliph Umar ibn al-Khattāb besought Yazdgerd III to convert to Islam. Yazdgerd III issued a reply in which he refuted that Zoroastrians were not polytheistic and highlighted that the Iranians were cultured and civilized in contrast to the Arabs. Though this letter's authenticity is questionable to say the least, and is most likely a forgery

Arabs occupied Ctesiphon, and the young King fled into Media. Yazdgerd III then fled eastward from one district to another, until at last he was killed by a local miller for his purse at Merv in 651.

The rest of the nobles who fled settled in central Asia where they contributed greatly in spreading Persian culture and language in those regions. They also contributed to the establishment of the first native Iranian dynasty, the Samanid dynasty, which sought to retain some Sassanid traditions while still promoting Islam.

The Zoroastrian religious calendar, which is still in use today, uses the regnal year of Yazdgerd III as its base year. Its calendar era (year numbering system), which is accompanied by a Y.Z. suffix, thus indicates the number of years since the emperor's coronation in 632 AD.
