The Dabuyid Dynasty, otherwise known as the Gaubarid Dynasty, was an Iranian Zoroastrian Dynasty ruled by a group of independent kings, called Ispahbads. Most of what is known about the Dabuyid Dynasty is from the later historian Ibn Isfandiyar’s Tarikh-I Tabaristan, written in the 13th Century. Although the dynasty was founded by Gil Gavbara in 642 CE, it was named after his son, Dabuya, who controlled the kingdom after his father’s death. Dabuyid rule extended over Tabaristan and western Khorasan until the Abbasid conquest in 760. The dynasty ended with the suicide of Khurshid after a surprise invasion by the Abbasid Caliphate.
