The Dabuyid ruler Farrukhan the Great (r. 712–728) is famous for successfully containing a large-scale invasion by the Umayyad general Yazid ibn al-Muhallab.

In the 640s, the Dabuyid prince Gil Gavbara (r. 642–660), who was a great-grandson of shahanshah Jamasp (r. 496–498/9), conquered all of Daylam and Gilan and planned on extending his conquests to Tabaristan. Its governor, Adhar Valash, requested the aid of (shahanshah) Yazdegerd III (r. 632–651). Being unable to suppress the revolt, Yazdegerd III instead acknowledged Gil Gavbara as the ruler of the regions, presumably to deter him from creating an independent realm. Gil Gavbara was given the titles of Padashwārgarshāh (shah of Padishkhwargar) and "Ispahbad of Khorasan". Thus a basically independent dynasty was created - it remained undependent until 760 CE, when it was finally defeated and conquered by the Abbasids.
