I want to know the answer to the following question:
How many eras are the Shahis divided into?
All the background I'm provided with is that "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.". Is that enough to answer the question?
