Dharmapala Kamboja
Dharmapala Kamboja was probably the last ruler of Kamboja Pala dynasty of Bengal. He ruled Dandabhukti-mandala in Vardhamana-bhukti in the first quarter of eleventh century and was contemporary of Rajendra Chola of Chola dynasty of Deccan.
- One king named Dharmapala ruling in Dandabhukti finds mention in the Tirmulai Inscription of Rajendra Chola which he issued in his 13th regnal year. Scholars identify this Dharmapala of the Tirmulai Inscription with the Dharmapala of the Kamboja-Pala Dynasty ruling in Dandabhukti in the first quarter of the 11th century. It has also been suggested that when threatened by Pala rulers of Bengal, Dharmapala, this last ruler of the Kamboja-Pala Dynasty of Bengal, might have sought help from Rajendra Chola of the Chola Dynasty.
- Chidambaram Inscription Tamil language, found in Chidambaram refers to one Kamboja ruler who made a beautiful stone gift as a curio to Rajendrasoladevar which with latter's permission, was embedded in front row of the edirambalam of the Nataraja temple:
- Karandai plates of about 1020 issued by Rajendra Chola in the eighth year of his reign states that a Kamboja king solicited friendship of Rajendra Chola by sending him for the protection of his royalty a victorious war-chariot with which he had defeated the armies which opposed him in battle. The inscription issued in the eighth year of his reign contains a significant verse in its separate Sanskrit section and it refers to one Kamboja Raja:
The Kamboja king mentioned in the Karandai plates is also believed to be Dharmapala of the Kamboja-Pala Dynasty of Bengal. There can also be no doubt that Dharmapala of the Tirumalai Inscription of king Rajendra Chola is the Kamboja king Dharmapala of Dandabhukti who was a scion of the Kamboja dynasty to which Nayapalaa, Narayanapala and Rajyapala of the Irda Copper Plate grant and the Kalanda Copper Plate grant belonged.
When threatened by the Pala ruler Mahpala-I, this Kamboja Dharmapala appears to have sought friendship and help with Rajendra Chola against the Pala ruler by forming an alliance with Rajendra Chola and presenting him a valuable Ratha as a token of friendship. As a consequence, Rajendra Chola led his victorious northern expedition to the banks of the Ganges and also met Dharmapala in Dandabhukti. This demonstrates Kamboja rulers' weakened position and Rajendra Chola's political influence in Bengal. Some scholars, however, think that “Kamboja king sent his ratha as a friendly present to Rajendra Chola to avoid war with the latter".
