The historical records mentioning this kingdom derived from Indian and Javanese sources. The state of Pannai, with river runs through it, was mentioned in the Tanjore inscription dating from the 11th century, as one of the polity sacked by Rajendra Chola I of Chola dynasty during his campaign against the prosperous Srivijaya. Three centuries later, Prapanca confirmed Pannai as one of the Malay states targeted in Majapahit's foreign diplomacy.
