The Pratapgarh Kingdom (Bengali: প্রতাপগড় রাজ্য) was a medieval state in the north-east of the Indian subcontinent. Composed of the present-day Indian district of Karimganj, as well as parts of Tripura State and Sylhet, Bangladesh, the kingdom was ruled by a line of Muslim monarchs over a mixed population of Hindu and Islamic adherents. It was bordered by the larger kingdoms of Kachar, Tripura and Bengal.
