Аршакиды
The historical pendant to the House of Tous could be found in a branch of the Parthian Arsacid Dynasty (247 BC to 224 AD), and the dispute between the royal heroes Tous and Godarz "may reflect a rivalry between two powerful Parthian noble houses". Such a war of succession happened when different lines of the Arsacides ("Ashkanian") struggled for becoming Great King of the Parthian Empire which was only known by later Persian historians as a kingdom of 18 "petty rulers" (Middle Persian: "kadak-khvaday"; Arabian: "moluk al-tawa'ef").
