The history of ancient India is interesting because India proved to be a melting pot of numerous races. The pre-Aryans, the Indo-Aryans, the Greeks, the Scythians, the Hunas, the Turks, etc., made India their home. Each ethnic group contributed its might to the making of Indian culture. All these peoples mixed up so inextricably with one another that at present none of them can be identified in their original form. Different cultures mingled with one another through the ages. Many pre-Aryan or Dravidian terms occur in the Vedic texts. Similarly, many Pali and Sanskritic terms appear in the Sangam literature. The History of India can be broadly divided into three phases.
