For a short period, the Cholas were overthrown by Simha Vishnu Pallava and the Region came under the Pallava rule for sometime. Vijayalaya Chola again revived Chola rule. This was the beginning of great Chola Empire. The later Chola rulers were weak and the power passed on to the hands of Eastern Chalukyas.
