The reign of the Somavamsis for two hundred years forms a glorious epoch in history of Odisha. For the first time Kalinga, Utkala, Kongoda and Kosala were unified and brought under one political authority. The uniform pattern of administration removed anarchy and confusion throughout the state and paved the way for a cultural synthesis leading to the emergence of a unique Odia culture. The Odishan temple architecture took a concrete shape during the Somavamsis and the kingdom witnessed peace and prosperity.
The Somavamsi rule undoubtedly ushered a new era in the history of medieval Odisha. The rulers of this dynasty were great conquerors who, by their extensive conquests, gave a geographical unity to this land by bringing a large chunk of territory comprising the undivided Balasore, Cuttack, Puri, Keonjhar, Dhenkanal, Baud-Kondamal and Ganjam districts of Odisha. Of course, their political achievements became shadowy in the foot-prints of time but their cultural activities remained uneffaceable for all times to come.
