The first important ruler was Siva Skandavarman who performed an Aswamedha and other Vedic sacrifices. His capital was kanchi. Samudragupta forced the pallava king, Vishnugopa, to acknowledge the Gupta suzerainty. And the story of the Pallavas in the 5th and 6th centuries is very sketchy.By end of the sixth century the Pallavas re-emerged on the scene. Simhavishnu (575 to 600 A.D.) captured the territory of the Cholas and humbled the pride of his neighbours including Ceylon. He was ovavaishnava faith as borne out by the magnificent reliefs representing Simhavishnu and two of his consorts in the Varsha cave at Mamallpuram.With Mahendravarman I, the son and successor of Simhavishnu, began thetitanic tripartite struggle with the Chalukyas of Vatapi and the Cholas. The Chalukya king, Pulakesin II, captured Kanchi. Pulakesin II won the pitched battle fought at Pullalur, fifteen miles north of Kanchi.However, Narsimhavaram I, the son and successor of Mahendravarman I, defeated pulskesin II in many battles and probably killed pulakesin himself. He also defeated the Cholas, the Cheras and the pandyas. He even sent two naval expeditions to Ceylon and placed his protégé on the throne of Ceylon. Narasimhavarman I was a great builder too. Mamallapuram was embellished during his time. Hiuen-Tsand visited his kingdom. He states that the soil was fertile and produced abundance of grain; flowers and fruits were many precious gems and other luxury articles were known; and the people were courageous and greatly attached to learning, honestry and truth.Narasimhavarman II. He too, fought with the chalukyas. He was succeeded by Paramesvaravarman I in whose reign Vikramadhitya I of the Chalukyas, in alliance with the Pandyas, renewed the hostilities. He probably captured the city of Kanchi. Later, Paramesvarvarman I defeated Vikramadhity II. The Pallava records claim that the Chalukya pattack was hurled back.
