Bengal Sultanate–Kamata Kingdom War

The Bengal Sultanate–Kamata Kingdom War was a conflict between the Bengal Sultanate and the Kamata Kingdom during the late 15th century. The war marked the expansion of Bengali rule into the Assam region.

Invasion
After assuming the throne, Alauddin Hussain Shah, the Sultan of Bengal, led his army to invade Assam in 1498. The invasion force included cavalry, infantry and the Bengal navy. The Bengal forces besieged the Kamatapur fort and destroyed the city. Hussain Shah defeated Nilambar of Kamata and ended the reign of the Khen dynasty. Hussain Shah continued into Upper Assam in the Brahmaputra Valley.

Aftermath
The region was brought under the administration of Bengali governors in Hajo. Hussain Shah minted coins with the proclamation "conqueror of Kamrupa, Kamata, Jajnagar and Orissa". His successors lost control of the region to the Koch dynasty.
