Peasants Movement against the king of Tripura in 1764 under the leadership of Samsher Gazi is a notable historical event. Born in an ordinary peasant family Shamsher Gazi became the ruler of the entire Chakla Raushanabad which was spread over the south of Comilla and the north of the Noakhali districts. Gradually he brought the whole of the Comilla district under his control. Later he conquered Nizampur Pargana, thus making himself the uncrowned king of the region between the Meghna, the Muhuri and the Manuganga rivers. Shamsher Gazi was born of a poor Muslim peasant family in the year 1712 at Kungura village under Dakshin Shik pargana north of Chittagong which formed part of Tripura's Manikya kingdom. While working as 'Tehshildar' in the local landlord Nasir Mohammed's office Shamsher is said to have received divine blessing of a 'Pir'.
