The Koch dynasty (Pron: kɒʧ; 1515–1949) ruled parts of eastern Indian subcontinent in present-day Assam and Bengal. Biswa Singha established power in the erstwhile Kamata Kingdom which had emerged from the decaying Kamarupa Kingdom. The dynasty came to power by removing the Baro-Bhuyans, who had earlier removed the short-lived rule established by Alauddin Hussain Shah.
