28 April 224, on a plain nobody can find
Ardashir I fought his Parthian overlord Artabanus on the plain of Hormozdgan on 28 April 224. Artabanus — numbered V in older scholarship, IV in newer — was defeated and killed, and the authority of the dominant Arsacid king went with him.
Where that plain lay is unresolved. Ram-Hormoz and the Golpayegan region are competing proposals; the battlefield has not been securely identified.
The tactics come from a late book
The vivid version — Ardashir reaching the field early, digging a defensive ditch, taking control of its spring before Artabanus arrived — reaches us through al-Tabari, probably drawing on a Sasanian official tradition written down long after the day itself.
The same tradition gives Ardashir about 10,000 horsemen and contrasts the two cavalries: some of his men in flexible chain mail, Artabanus's troops in heavier lamellar armor.
The rock relief at Firuzabad that commemorates the battle is a royal image rather than an eyewitness record — 18 meters long and nearly 4 meters high.
What survived Artabanus
One scholarly reconstruction has Ardashir assuming the title shahanshah, king of kings, while still on the battlefield. Others place a coronation at Ctesiphon around 226; the sources disagree.
The victory brought the Sasanians to power, but the conquest and consolidation of former Parthian territory continued afterward, and Artabanus's brother Vologases VI remained a rival Arsacid king.
The evidence for Vologases's authority after 224 is principally numismatic — a single reported coin dated 227/228, whose historical implications have been challenged.

What the sources leave uncertain
- The battlefield has not been securely identified. Ram-Hormoz and the Golpayegan region are competing proposals.
- The detailed tactical story—an early arrival, defensive ditch and control of a spring—comes through al-Tabari, probably drawing on a Sasanian official tradition written long after the event.
- Sources disagree over whether Ardashir assumed the title “king of kings” immediately or underwent a later coronation at Ctesiphon around 226.
- The single reported Vologases VI coin dated 227/228 has disputed historical implications; it does not securely establish the extent of his post-224 rule.
