The earliest mention of a kingdom comes from the 4th-century Allahabad inscription of Samudragupta that calls the kings of Kamarupa and Davaka frontier rulers ("pratyanta nripati"). The Chinese traveller Xuanzang visited the kingdom in the 7th century, then ruled by Bhaskaravarman. The corpus of Kamarupa inscriptions left by the rulers of Kamarupa at various places in Assam and present-day Bangladesh are important sources of information. Nevertheless, local grants completely eschew the name Kamarupa; instead they use the name Pragjyotisha, with the kings called "Pragjyotishadhipati".
