A peace-loving and agrarian culture, the Dravidians appeared to be more advanced than the Vedic Aryans who, according to legend, invaded the Indian subcontinent around 1500 B.C.E., forcing the Dravidians to the south of India. As a result of the invasion, the cultures became mixed and the Aryans absorbed many of the Dravidian traditions. The practices and traditions of yoga that are part of the Vedic tradition today likely have Dravidian origins.
The ancient Hindu scripture, the "Rig Veda," describes the destruction of Harappa by the Aryan invaders, although Harappa culture may already have been disintegrating when the Aryans invaded.
The Dravidian family of 70 languages are spoken by more than 215 million people in India, Sri Lanka and Pakistan. Telugu, Malayalam, Tamil and Kannada - the four major literary languages - are listed in India's constitution as receiving official status.
