[13] Many other scholars say that Kamboja of Chidambram inscriptions is this Dharampala of Kamboj lineage who was ruling in Dandbhukti-mandala of west Bengal during early 11th century and was therefore a contemporary of Rajendra Chola.
[17][18] The Kamboja king mentioned in the Karandai (Tanjavur or Tanjore) plates (v.48) 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.
[19][20][21][22] 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 (Chariot) 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.
