Asura kingdom, or Sonitpura kingdom, is a mythological kingdom that is mentioned in a multiple of Hindu epics[1] which later came to be associated with modern-day Tezpur in central Assam and Banasura Hill in Kerala.
The kingdom was contemporary of Pragjyotisha.
In Puranic literature, Pragjyotisha and Sonitpura were located to the north-west of the Indian subcontinent in what is modern-day Punjab and Sindh.
[2] In Assam, the name of the legendary kingdom might be applied to the local inhabitants who were outside of the Hindu fold.
[3] In Kalika purana, Banasura, the last ruler of the asura kingdom is represented as an anti-Brahminical character.
