Ardashir's brother left coins calling himself king — physical evidence that complicates the later tale of a simple usurpation.

Three dates for one rise

The traditional date for Ardashir's accession as king of Persis is 208. No secure contemporary narrative fixes the fraternal revolt there.

An Encyclopaedia Iranica chronology puts his open rebellion in 212, while another interpretation of a Bishapur inscription places an early stage of the family revolt or consolidation in 205–206.

The brother in the story, and the brother on the coins

In the traditional reconstruction, Papak's elder son Shapur became king of Persis; Ardashir rebelled against him and took the kingship after Shapur died suddenly in an accident — if that later tradition can be trusted.

Coins confirm that Shapur ruled as king and associated himself with his father Papak. They do not establish a securely dated fraternal war in 208.

Not the founding of an empire

Ardashir did not establish the Sasanian imperial regime in 208. Local control of Istakhr or Persis was not the same thing as overthrowing the Arsacid King of Kings.

That came later: he defeated the Arsacid king Artabanus at Hormozdgan on 28 April 224 and assumed the title King of Kings — sixteen years after the traditional accession date.

Date disputed. Sources disagree; the research places it at ~0208.

What the sources leave uncertain

  • No secure contemporary narrative fixes the fraternal revolt to 208.
  • Modern reconstructions offer 205–206, 208, and 212 for different stages of Papak and Ardashir’s rise.
  • The story of Shapur preparing to fight Ardashir before dying in an accident comes from later narrative tradition and is challenged by evidence treating Shapur as a legitimate king.
  • The Sasanian dynasty’s local family history must be distinguished from the establishment of the Sasanian imperial regime in 224.
