Gil Gavbara (Persian: گیل گاوباره), also known as Gavbarih (the Cow Devotee[1]), was a general and founder of the Dabuyid dynasty in 642, ruling until his death in 660.
According to Ibn Isfandiyar, the Dabuyids were descended from Djamasp, a brother of the Sassanid shah Kavadh I. Gil Gavbara was the grandson of Piruz, who is described as brave as the Iranian mythological hero Rostam.
[2][3] Piruz died around 642 and was succeeded by Gil Gavbara as the ruler of Gilan.
Gil Gavbara, together with Farrukhzad from the House of Ispahbudhan, signed a peace treaty with the Arab conquerors[4] and was given control of Tabaristan, which led to the formal conferment of the titles of Gil-Gilan ("ruler of Gilan") and Padashwargarshah ("Shah of Patashwargar", the old name of Tabaristan's mountains) to Gil Gavbara's son Dabuya by Yazdegerd III, the last Sasanian shah.
