Iraj (Persian: ایرج|ʾīraj; Pahlavi: ērič; from Avestan: Avestan: {{script|Avst|, literally "Aryan") is the seventh Shah of the Pishdadian dynasty, depicted in the Shahnameh. Based on Iranian mythology, he is the youngest son of Fereydun. In the Avestan legends, Pahlavi literature, Sasanian-based Persian sources, some Persian sources, and particularly in Shahnameh, he is considered the name-giver of the Iranian nation, the ancestor of their royal houses, and a paragon of those slain in defense of just causes.[1]
