Kamarupa (; also called Pragjyotisha), was one of the historical kingdoms of Assam alongside Davaka, that existed from 350 to 1140 CE. Ruled by three dynasties from their capitals in present-day Guwahati, North Guwahati and Tezpur, it at its height covered the entire Brahmaputra Valley, North Bengal, Bhutan and parts of Bangladesh, and at times portions of West Bengal and Bihar.
