The Pala Dynasty originated in the region of Bengal as an imperial power during the Late Classical period  on the Indian subcontinent. The dynasty was named after its ruling dynasty, whose rulers bore names ending with the suffix of Palau, which meant protector.  Pala empire was founded by Gopala I, probably in 750 A.D. when he was elected king.   He was succeeded by Dharmapala who is considered as the real founder of the Pala Empire and Pala suzerainty.  Vikramasila University was founded by Dharmapala, where several Buddhist scholars and monks  were invited to study. The empire enjoyed relations with the Srivijaya Empire, the Tibetan Empire, the Sailendra Empire  of Java, and the Arab Abbasid Caliphate.  The Arab Merchant Sulaiman wrote detailed accounts about the Pala empire, its military, structure, and other features.
