Explanation:

The Pallavas, who left behind magnificent sculptures and temples, established the foundations of medieval South Indian architecture. They developed the Pallava script from whichGrantha ultimately descended. The Pallava script gave rise to several other southeast Asian scripts.Chinese traveller Xuanzang visited Kanchipuram during Pallava rule and extolled their benign rule.
The Pallavas gained prominence after the eclipse of the Satavahana dynasty, whom the Pallavas served as feudatories.Throughout their reign they were in constant conflict with both Chalukyas of Badami in the north and the Tamil kingdoms of Chola and Pandyas in the south and were finally defeated by the Chola kings in the 9th century CE.
