The ancient period can be said to be from around the 7th century when the Tripuri kings ruled from Kailashahar in North Tripura and they used “fa” as their title, “pha” in Kokborok means “father” or “head”.

The Kings of Tripura adopted the “manikya” title and shifted their capital to Udaipur (formerly Rangamati) on the banks of the River Gomti in South Tripura in the 14th century. This was their most glorious period and their power and fame was even acknowledged by the Mughals, who were their contemporaries in North India.
