Dabuyid dynastyThe Dabuyid dynasty, or Gaubarid dynasty, was a Zoroastrian Iranian dynasty that started in the first half of the 7th century as an independent group of rulers that ruled over Tabaristan and parts of western Khorasan. Dabuyid rule over Tabaristan and Khorasan lasted from around 642 to the Abbasid conquest in 760. The family's early history is recorded by the later historian Ibn Isfandiyar. According to that tradition, the Dabuyids were descended from Jamasp, a son of Sassanid King of Kings Peroz I and younger brother of Kavadh I, and were therefore a cadet branch of the House of Sasan.
