The Bijni branch of the Koch dynasty controlled its feudatory from the present-day Bijni town from 1671 till 1864 when it was attacked by Jhawlia Mech , a chieftain from Bhutan . This resulted in the capital moving to Dumuria . The earthquake of 1897 destroyed the royal palaces and the capital moved again , first to Jogighopa and then finally to Abhayapuri in 1901 . The control of the Bijni branch ended after the Indian government took direct control of the region in 1956
