Patna State was a princely state in the Eastern States Agency of India during the British Raj. It had its capital at Balangir. Its area was 6503 km2.

History

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 extended over the region under its cadet branches which included 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.
