According to the royal reports, it was Papak who overthrew Gochihr, the local Persian shah, and appointed his son, Shapur, instead of him; Ardashir refused to accept Shapur's appointment and removed his brother and whosoever stood against him and then minted coins with his face drawn on and his father, Papak's behind. It is probable that the determining role that is stated about Ardashir in leading the rebellion against the central government is the product of the later historical studies. Papak had probably united most of Pars under his rule by then.
