Name Fereydun

Fereydūn (Persian: فریدون) in Tajik Faridun or (arabicized) Afrīdūn (Medieval Persian: Firēdūn, Middle Persian: Frēdōn, Avestan Θraētaona), also called Apam Napat, "Son of the Waters", is the name of an Iranian mythical king and hero who is an emblem of victory, justice and generosity in the Persian literature.
Fereydun in the Shāhnāmeh According to Ferdowsi’s Shāhnāmeh, Fereydun was the son of Ābtīn, one of descendants of Jamshid. Fereydun, together with Kaveh, revolted against the tyrannical king “Zahhāk”, defeated and arrested him in the Alborz Mountains. Afterwards Fereydun became the king and, according to the myth, ruled the country for about 500 years. At the end of his life he allocated his kingdom to his three sons; Salm, Tur, and Iraj. Iraj was Fereydun’s youngest and favored son and inherited the best part of the kingdom, namely Iran. Salm inherited Asia Minor ("Rūm", more generally meaning the Roman Empire, the Greco-Roman world, or just "the West") and Tur inherited Central Asia ("Tūrān", all the lands north and east of the Oxus, as far as China), respectively. This aroused Iraj’s brothers’ envy and encouraged them to murder him. After Iraj’s murder, Fereydun enthroned Iraj’s grandson, Manūchehr. Manūchehr’s attempt to avenge his grandfather’s murder initiated the Iranian-Turanian wars.
