Shapur II
According to Ammianus Marcellinus, Shapur II fought the Romans in order to "re-conquer what had belonged to his ancestor". It is not known who Shapur II thought his ancestor was, probably the Achaemenids or the legendary Kayanian dynasty. During the reign of Shapur II, the title of "the divine Mazda-worshipping, king of kings of the Iranians, whose image/seed is from the gods" disappears from the coins that were minted. He was also the last Sasanian king to claim lineage from the gods.
