The Kabul Shahi dynasties ruled the Kabul Valley and Gandhara (modern-day Pakistan and Afghanistan) from the decline of the Kushan Empire in the 3rd century to the early 9th century. The Shahis are generally split up into two eras: the Buddhist Shahis and the Hindu Shahis, with the change-over thought to have occurred sometime around 870. The kingdom was known as the Kabul Shahan or Ratbelshahan from 565-670, when the capitals were located in Kapisa and Kabul, and later Udabhandapura, also known as Hund for its new capital.

When did the Shahis switch from Buddhist to Hindu?
