Ratnapura
Ratnapura was a kingdom of the eastern Kalachuri, or Haihaya, dynasty in Dakshina Kosala. Its capital was founded by Ratna-deva I.
In the late fourteenth century the house split into Ratanpur and Raipur branches. The hills sheltered the country from northern invasions, but in 1740 its rajas accepted the suzerainty of the Bhonsles of Nagpur. After Mohan Singh died about 1758, the Bhonsles annexed the kingdom.
