Towards the middle of the sixth century A.D. and more obviously at the advent of the seventh century A.D., the obscure political scene of Odisha became clear to some extent. In the political scenario of Odisha, the Sailodbhavas emerged as a mighty power extending their sway from the Mahanadi in the north to Mahendragiri in the south. They ruled over Kongoda Mandala, roughly comprising the undivided Ganjam and Puri districts. The centre of their political activities was Kongodavasaka which was, perhaps, on the bank of river Salia in the Ganjam district.
The Ekamra Purana Kapila Samhita, Svarnadri Mahodaya and Hiuen Tsang’s Si-yu-ki help a lot in constructing the history of the Sailodbhavas. The Sumandala plate, Kanasa copper plate grant, Soro charter, Chicacole plates, Khurda grant, Tekkali charter, Ganjam plates etc. form the inscriptional sources for the dynasty.
To conclude it can be said that the Sailodbhava rule cannot be considered to be of much importance from the political point of view. They were feudatories, ruling over a small territory and asserted their independence at opportune moments. Their historical significance lies in the fact that from them onwards we get a regular dynastic history of Odisha. The Sailodbhava period was a period of creativity in Odishan art and architecture. A number of Saiva temples like Parsurameswar, Bharteswar, Laxmaneswar, Satrughnesvar, svarnajaleswar etc. can be assigned to Sailodbhava period
