the Kamboja-Pala kings of Bengal i.e. Rajyapala, Narayanapala and Nayapala etc. The Kamboja-Pala kings of the Irda Copper plate had ruled north-west Bengal in the tenth or eleventh century. Bangar Grant of Mahipala I Bangar Charter of Mahipala I is the third very important ancient source of Kamboja rule in Bengal. The charter asserts that Mahipala had re-conquered nearly the whole of north and east Bengal "after defeating the usurpers who had seized his ancestral kingdom". The same verse has been repeated in the Aamgaachhi Charter of Vigrahapala-3. But "Who were the usurpers the inscription does not tell, but other evidences indicate that the rulers belonging to the Kamboja family were in possession of the north and west Bengal". Scholars believe that Mahipala's Charter alludes to the seizing of the northern parts of Bengal by Kamboja dynasty from the Gopala II or Vigrahapala II of the Pala dynasty, which the great king Mahipala I claims to have won back by the force of his arms Extent of Kamboja Empire No definite information is available on the precise geographical area of the Kamboja-Pala kingdom of Bengal. According to Irda Copper plate evidence, the Kamboja-Pala kingdom definitely comprised Varadhmana-Bhukti Mandala (modern Burdman division) and Dandabhukti Mandala within the Kamboja empire. The Dandabhukti division is believed to have comprised southern and south-western parts of Midnapore district as well as the lower parts of river Suvaranrekha in district Balasore. Evidence from Dinajpore Pillar Inscription attests that the Gauda country also formed parts of Kamboja-Pala kingdom. But as long as we do not include northern Ladha (Radha or W. Bengal) in Kamboja-Pala empire, the region does not constitute one viable political entity. Hence it appears likely that northern parts of Radha may also formed parts of Kamboja-Pala kingdom. Dr R. C. Majumdar says that Gauda and Radha both formed parts of Kamboja-Pala empire During second half of the 10th century, the Chandela ruler Yashovarman invaded the Pala kingdom. Vakpati, a courtier-poet, claims that he conquered Gauda and Mithila. It is also stated that Chandela chief Dhanga of Jejabhukti, the successor of Yashovarman, had invaded Radha towards the end of the 10th century. As a consequence, the Kamboja power in the north Bengal received a severe jolt. This political scenario enabled the Pala king Mahipala I to re-conquer Gauda from the Kambojas. The last king of the Kambojas was Dharamapala who continued to rule Dandabhukti in
