Kamarupa (late to end period)

[citation needed] The ruler was legitimized with the claim that Brahma Pala was a descendant of the Varman dynasty and that he was elected by the people.

[1][failed verification] During Brahma Pala's reign Kamarupa was attacked by Jatavarman, son of Vajravarman of the Varman dynasty which ruled probably in Eastern Magadha when the Pala power began to wane.

This invasion is mentioned in the Belava copper-plate inscription of Bhojavarman,[1][failed verification] the grandson of Jatavarman, who thereby granted lands in the Paundra bhukti, the grant being issued from the victorious camp at Vikramapura.

It is stated in verse 8 of this inscription that It appears that Jatavarman invaded Kamarupa and defeated its king but could not annex the kingdom.

It is probable that after this defeat Brahma Pala abdicated in favour of his son Ratna Pala who appears to have removed the capital to Guwahati, on the banks of the Brahmaputra, and, after fortifying it, called it Durjaya or impregnable.
