The foundation of the Patna kingdom was laid by Ramai Deva of the Chauhan dynasty in 1360 CE when he overthrew Hattahamir Deb, the administrator of the region as the Eastern Ganga Empire started weakening following invasions from the northern part of the subcontinent. The Chauhan reign eventually extends over the region under its cadet branches which include the kingdoms of Sambalpur State, Sonepur State and the zamindaries of Khariar and Jarasingha. The history of the Chauhan rule in the region is also obtained from the 16th century palm-leaf manuscript Kosalananda Kavya.
After Indian independence, Patna's last ruler Rajendra Narayan Singh Deo acceded to the newly independent Dominion of India, on 1 January 1948 with the state forming much of the present day Balangir district. Rajendra Narayan Singh Deo, built a new career as an elected politician and served as Chief Minister of Orissa from 8 March 1967 to 9 January 1971.
