Narasimhavarman, still seething at the Chalukyas’ seizure in 624 of the Visnukindin east coast kingdom of Vengi, which the Pallavas had themselves coveted, raids the Deccan area from 641 to 647, capturing large areas of Chalukya territory, conquering the temple-fort of Vatapi (Badami) in 642 and killing Pulakesi.

There is a period of confusion following the crushing defeat of the Chalukyas and the burning of Badami.

The five sons of Pulakesi fight among themselves and try to divide the kingdom into independent kingdoms.

Pulakesi's third son Vikramaditya I becomes the Chalukya king around 642 and eventually restores order after defeating his brothers.
