Kamata

Kamata was a kingdom in western Assam and northern Bengal, ruled from Kamatapur. In 1337 Durlabh Narayan held the throne.

An invasion by Bengal's Sultan Sikandar Shah weakened Indra Narayan, allowing Arimatta to seize power. The Khen dynasty followed, but in 1498 Bengal's Alauddin Husain Shah took Kamatapur after a long siege. Biswa Singha founded the Koch dynasty in 1515; after Nara Narayan died in 1587, the kingdom split into Koch Bihar and Koch Hajo, the latter eventually absorbed by the Ahoms.
