Kubja Vishnuvardhana

Kubja Vishnuvardhana I "Vishama-Siddhi" whose Kannada name was Bittarasa ^[1][2](reigned 624–641 AD) was the brother of Chalukya Pulakeshin II. Vishnuvardhana I ruled the Vengi territories in eastern Andhra Pradesh as the viceroy under Pulakeshin II from around 615 AD. Eventually, Vishnuvardhana declared his independence and started the Eastern Chalukya dynasty in (c. 624) AD.

The Eastern Chalukyas ruled the Vengi kingdom for nearly five centuries and had a very close relationship with the imperial Cholas.
