Q. Which dynasty came to rule in Bengal after the Palas?
Answer: Sena dynasty
Notes: The Sena Dynasty supplanted the Palas in Bengal towards the close of the 11th century AD. Hemantasena, the founder of the dynasty, was originally a tributary of the Pala dynasty. In the mid-eleventh century he declared his independence and set himself up as king. His successor, Vijayasena, built an empire on the ruins of that of the Palas, gaining control of all Bengal and northern Bihar.
