Introduction
Tur is the second son of Fereydun, given rule over Turan (Central Asia) in his father's division of the kingdom, a region traditionally understood to take its name from him. Like his elder brother Salm, his jealousy over the favourable portion given to their youngest brother Iraj led him to conspire in Iraj's murder, setting in motion the long war between Iran and Turan.
Family
Conspiracy against Iraj
Tur joined Salm in resenting their father's division of the kingdom, which gave the choicest lands, Iran, to their youngest brother Iraj. Together they murdered Iraj, and in some versions of the story, it is Tur personally who deals the fatal blow, sending Iraj's severed head back to their father Fereydun as a cruel trophy.
Death and legacy
Tur was eventually killed, along with his brother Salm, by Manuchehr, Iraj's avenging grandson. The land of Turan, and the peoples associated with it in the Shahnameh, most prominently under the later King Afrasiyab, remain Iran's great rival and adversary throughout the rest of the epic, a conflict whose origin traces directly back to Tur and Salm's murder of Iraj.
