Patna
Patna was a Chauhan Rajput kingdom of western Orissa, centred on Patnagarh in the Mahanadi basin. In the early fourteenth century, it lay under the loose suzerainty of the Eastern Ganga kings, whose administrator ruled through eight local Gauntia chiefs.
In 1360 Ramai Deva overthrew the chiefs with popular support, became raja and built the Patneswari temple at Patnagarh. His descendants founded branches at Sambalpur and Sonepur. In the eighteenth century Patna became tributary to the Marathas of Nagpur and later passed under British protection.
