Kubja Vishnuvardhana (reigned 624–641) was the brother of Chalukya Pulakeshin II. Vishnuvardhana ruled the Vengi territories in the eastern Andhra Pradesh as the viceroy under Pulakeshin II from around 615. Eventually Vishnuvardhana declared his independence and started the Eastern Chalukya dynasty (c. 624).
The Eastern Chalukyas ruled the Vengi kingdom for nearly five centuries and had very close relationship with the imperial Cholas.
Origin of Eastern ChalukyasEdit
Pulakeshin II (608–644), the greatest Vatapi Chalukya king, conquered the eastern Deccan, corresponding the coastal districts of Andhra Pradesh 616, defeating the remnants of the Vishnukundina kingdom. He appointed his brother Kubja Vishnuvardhana as Viceroy. On the death of Pulakeshin II, the Vengi Viceroyalty developed into an independent kingdom. Eastern Chalukyas of Vengi outlived the main Vatapi dynasty by many generations.
Possible reason for the partitionEdit

Scholars are not in agreement as to why Vishnuvardhana declared himself king of the eastern Deccan territories of Pulakeshin II. What was the necessity for the partition of Vengi as a separate kingdom from the Badami Chalukyan empire? Hitherto it has been tacitly assumed that this was a formal division and Pulakeshin II conferred independent sovereignty of Vengi on his younger brother. It is improbable that a great warrior like Pulakeshin II could not have administered Vengi as part of his kingdom and felt the need for a separate king. Kopparam plates make it clear that Kubja Vishnuvardhana was ruling only as a subordinate to his brother Pulakeshin II in the Vengi area. A revolution of Kubja Vishnuvardhana can be ruled out of account since he seems to have been very loyal and affectionate towards his brother.
One possible reason could be the turn of events around middle of the 7th century in the Western Chalukyan kingdom. The last few ruling years of Pulakeshin II ended in disaster. The great Pallava king Narasimhavarman I, inflicted a crushing defeat on the Chalukyas and burnt Badami. Pulakeshin II lost his life in this encounter. There was a period of confusion following these events. The five sons of Pulakeshin fought among themselves and tried to divide the kingdom into independent kingdoms. Pulakeshin's third son Vikramaditya I became the Chalukya king c. 642 and eventually restored order after defeating his brothers.
Vishnuvardhana ruled over a kingdom extending from Nellore to Visakhapatnam. He assumed the title of Vishamasiddhi (conqueror of difficulties). Vishnuvardhana participated in the wars between his brother Putekesin II and the Pallava Narasimhavarma I and probably lost his life in battle in 641.
His son Jayasimha I succeeded him.
