the south, and the whole output of this archaic literature exhibits unmistakably considerable Brahman influence in the making up of that literature. Medieval period The Cholas who were very active during the Sangam age were entirely absent during the first few centuries. The period started with the rivalry between the Pandyas and the Pallavas, which in turn caused the revival of the Cholas. The Cholas went on to becoming a great power. Their decline saw the brief resurgence of the Pandyas. This period was also that of the re-invigorated Hinduism during which temple building and religious literature were at their best. The Cheras ruled in southern India from before the Sangam era (300 BCE–250 CE) over the Coimbatore, Karur, Salem Districts in present-day Tamil Nadu and present day Kerala from the capital of Vanchi Muthur in the west, (thought to be modern Karur). The Kalabhras, invaded and displaced the three Tamil kingdoms and ruled between the 3rd and the 6th centuries CE of the Sangam period. This is referred to as the Dark Age in Tamil history and Hinduism in Tamil Nadu. They were expelled by the Pallavas and the Pandyas in the 6th century. During the Kalabhras' rule, Jainism flourished in the land of the Tamils, and Hinduism was suppressed. Because the Kalabhras gave protection to Jains and perhaps Buddhists, too, some have concluded that they were anti-Hindu, although this latter view is disputed. During the 4th to 8th centuries CE, Tamil Nadu saw the rise of the Pallavas under Mahendravarman I and his son Mamalla Narasimhavarman I. Pallavas ruled a large portion of South India with Kanchipuram as their capital. Mahendra Varman was principally a Buddhist, but converted to Hinduism by the influence of Shaiva saints. It was under him that Dravidian architecture reached its peak with the Pallava built Hindu temples. Narasimhavarman II built the Shore Temple which is a UNESCO World Heritage Site. The Pallavas were replaced by the Cholas as the dominant kingdom in the 10th century CE and they in turn were replaced by Pandyas in the 13th century CE with their capital as Madurai. Temples such as the Meenakshi Amman Temple at Madurai and Nellaiappar Temple at Tirunelveli are the best examples of Pandyan temple architecture.
