Kokrajhar
Kokrajhar lies north of the Brahmaputra in the eastern Duars, the low country at the foot of the Bhutan hills. The region stretches between the Sankosh and Manas rivers, where streams descend from the mountains onto the floodplain. From the early seventeenth century the Bhutanese kingdom exercised authority over parts of these passes and plains. The Duars linked the hill country with the markets and settlements of the Brahmaputra valley.
