Zunbil, also written as Zhunbil, or Rutbils of Zabulistan, was a royal dynasty south of the Hindu Kush in present southern Afghanistan region. They ruled from circa 680 AD until the Saffarid conquest in 870 AD. The Zunbil dynasty was founded by Rutbil (Turkic: Iltäbär), the elder brother of the Turk Shahi ruler (either Barha Tegin or Tegin Shah), who ruled over a Khalaj -Hephthalite kingdom from his capital in Kabul. The Zunbils are described as having Turkish troops in their service by Arabic sources like Tarikh al-Tabari and Tarikh-i Sistan.
