Limited written records from the medieval period in Arunachal Pradesh necessitate reliance on archaeological evidence, oral traditions, and accounts from neighboring kingdoms.

• Archaeological evidence can provide information about the material culture of a people, such as their tools, weapons, and pottery. It can also provide information about their social structure, such as their religious beliefs and practices.
• Oral traditions are stories that are passed down from generation to generation through word of mouth. They can provide information about a people’s history, culture, and beliefs.

Archaeological evidence can be difficult to interpret, oral traditions can be inaccurate, and accounts from neighboring kingdoms can be biased.
