Zunbil, also written as Zhunbil, was a dynasty south of the Hindu Kush in present southern Afghanistan region. They ruled from the early 7th century until the Islamic conquest of Afghanistan in 870 AD. The Zunbils are believed to be an offspring of the southern-Hephthalite rulers of Zabulistan. The dynasty was related to the Kabul Shahis of the northeast in Kabul. "It follows from Huei-ch'ao's report that Barhatakin had two sons: one who ruled from after him in Kapisa-Gandhara and another who became king of Zabul".
The Zunbils worshipped the sun, which they named Zun (read as /zuːn/; ZOON) from which they derived their name. Their territory included between what is now the city of Zaranj in southwestern Afghanistan and Kabulistan in the northeast, with Zamindawar and Ghazni serving as their capitals. The title Zunbil can be traced back to the Middle-Persian original Zūn-dātbar, 'Zun the Justice-giver'. The geographical name Zamindawar would also reflect this, from Middle Persian 'Zamin-i dātbar' (Land of the Justice-giver).
According to Anthony McNicoll, "the Zunbils ruled in the Kandahar area for nearly 250 years until the late 9th century AD". Their main capital Zamindawar was located in the present-day Helmand Province of Afghanistan. The shrine of Zoon (sun god) was located about three miles south of Musa Qala in Helmand, which may still be traced today. Some believe that the Sunagir temple mentioned by the famous Chinese traveler Xuanzang in 640 AD pertains to this exact house of worship.
