Iraj (Persian: ? - raj; Pahlaviri?; from Avestan: airiia, literally "Aryan") is seventh Shah of the Pishdadian dynasty of Shahnameh. Based on Iranian mythology, he is the youngest son of Fereydun. In the Avestan legends, Pahlavi literature, Sasanian-based Persian sources, some Arabic 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.
Iraj was Fereydoun's third and last child. He was trusted by his father to fight the Dragon, and Fereydoun considered him better suited to his kingdom than his two children. But Iraj was assassinated by two brothers before the kingdom.
When Fereydun divides his kingdom, he gives Iraj the Farr -- the favor of God -- as well as the heartland of Iran. Salm and Tur conspire and kill Iraj. The revenge for the murder of the innocent king pits the clan of Iraj, supported by King Fereydun, against the clan of Tur. Subsequently, Manu?ehr, Iraj's grandson from a slave maiden, kills both Salm and Tur. As for Fereydun, he abdicated in favor of his grandson, Manu?ehr.
