Describe the political and cultural achievements of the Pallava dynasty.

The Pallava dynasty reached its peak period in the 7th century with Kānchī as its capital. They reached their peak under Mahendravarman I and his son Narasimhavarman I, who defeated Pulakeśhin II and captured Badami. The Pallavas built rock-cut and monolithic temples at Māmallapuram depicting deities and Mahābhārata scenes. They patronised Jain, Vaishnavite, and Shaivite traditions. They promoted Sanskrit and Tamil literature, with poets like Daṇḍin flourishing under them. Kanchipuram was an important cultural centre and economic hub, with trade in spices, textiles, ivory, and luxury goods through the seaport at Māmallapuram.
