An inscription found in Arang testifies to the sovereignty of the Guptas in this area.

Accounts dating back to 1114 A.D., mention that the first chief of the Haihayavanshi line conquered Dakshina Kosala around the 10th Century. A powerful chief known as Jagpal is believed to have ruled over Raipur and Durg areas under the domain of the upper branch of the Haihayas at Ratanpur.
