The Bijni Kingdom was situated between 250 53' and 260 32' N. and 900 85' and 910 85' E. The estate was in possession of the Bijni family, descended from the Koch king Nara Narayan, who reigned over Kamata kingdom from 1534 to 1584. Before his death, Nara Narayana allowed his kingdom to be divided between his son Lakshmi Narayan and his nephew Raghu Rai (son of Chilarai). Raghu Rai established his capital at Barnagar in the Barpeta (now a district in Assam), and received as his share the Koch territories lying to the east of Sankosh River.
