Kamarupa, an early state during the Classical period on the Indian subcontinent, was the first historical kingdom of Assam.

The middle kingdoms of India were the political entities in the Indian subcontinent from 230 BCE to 1206 CE. The period begins after the decline of the Maurya Empire and the corresponding rise of the Satavahana dynasty, starting with Simuka, from 230 BCE. The "middle" period lasted for almost 1436 years and ended in 1206 CE, with the rise of the Delhi Sultanate, founded in 1206, and the end of the Later Cholas.
