Kāve ye Āhangar
Kāveh was, according to ancient legends, a blacksmith who launched a national uprising against the evil foreign tyrant Zahāk, after losing two of his children to serpents of Zahāk. Kāveh expelled the foreigners and re-established the rule of Iranians.[3] Many followed Kāveh to the Alborz Mountains in Damāvand, where Fereydun, son of Ābtin and Faranak was living. Then a young man, Fereydun agreed to lead the people against Zahāk. Zahāk had already left his capital, which fell to Fereydun's troops with small resistance. Fereydun released all of Zahāk’s prisoners.
The end!
