In Iranian mythology, Kave was a blacksmith that led an uprising against the ruthless foreign ruler Zahak, who had seized the throne. The history of Kave the Blacksmith was described in the holy “Avesta” and later retold in “Shahname” by Firdowsi poet.
In “Shahname” it is told that Kave had eighteen sons and seventeen of them fell victim to a monstrous snake growing up from the shoulders of the tyrant Zahak. When the snake finished eating the head of the seventeenth son and was getting ready to attack the last one, the blacksmith went to the palace for justice. Zahak, to protect his rights to the throne, wrote regulations about his justice. He listened to the blacksmith’s complaint demonstratively and calmly and released his last son asking him to sign the regulations. Double game of Zahak made Kave mad. He threw the letter, ran away with his son from the palace.
Kave, attaching his leather apron to the spear, gathered people and lead to Fereydun, the ruler by right. Thus, the first flag of the Iranian people was created. Fereydun got inspired by the flag and decorated it with a golden star with four rays, ribbons of red, yellow and purple colors and precious stones. He called the flag “Derafsh Kavian” (the flag of Kave). The rebels, the blacksmith and Fereydun overthrow Zahak and got back the throne.
