Gil Gavbara

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. Piruz later became the ruler of Gilan, and married a local princess who bore him a son named Gilanshah, who in turn had a son, Gil Gavbara.[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.
