The Satavahana dynasty dominated the Deccan region from the 1st century BCE to the 3rd century CE. The later Satavahanas made Dharanikota and Amaravathi their capital, which according to the Buddhists is the place where Nagarjuna, the philosopher of Mahayana lived in the 2nd and 3rd centuries. The Andhra Ikshvakus, with their capital at Vijayapuri, succeeded the Satavahanas in the Krishna River valley in the latter half of the 2nd century. Pallavas, who were originally executive officers under the Satavahana kings, were not a recognised political power before the 2nd century CE and were swept away by the Western Chalukyan invasion, led by Pulakesin II in the first quarter of the 7th century CE. After the downfall of the Ikshvakus, the Vishnukundinas were the first great dynasty in the 5th and 6th centuries, and held sway over the entire Andhra country, including Kalinga and parts of Telangana. They played an important role in the history of Deccan during the 5th and 6th century CE, with Eluru, Amaravathi and Puranisangam.
