Kurdish people
During the Sassanid era, in "Kar-Namag i Ardashir i Pabagan" a short prose work written in Middle Persian, Ardashir I (founder of Sasanian empire) is depicted as having battled the Kurds and their leader, Madig. After initially sustaining a heavy defeat, Ardashir I was successful in subjugating the Kurds. In a letter sent by Ardashir's enemy, Ardavan, and in the same work, it is stated that he was a Kurd.You've bitten off more than you can chew and you have brought death to yourself. O son of a Kurd, raised in the tents of the Kurds, who gave you permission to put a crown on your head?
