Arya is a Sanskrit word meaning “a noble one” or “one who does noble deeds." In Sanskrit literature, Aryavarta, or “abode of the Aryas,” is the name given to northern India.
The large-scale migration of the Aryan people into the Indian subcontinent is believed to have occurred before 1500 B.C.E. They were nomadic cattle herders and would have come into contact with the Indus Valley civilization, a civilization which was likely already decaying with the drying up of the Saraswati River in some parts and flooding in other parts.
With the Aryan migration, the Aryan language gradually began to take over the area. The ancient Aryan people likely worshiped the Vedic deities, especially Indra, and their religion and writing strongly influenced the ongoing development of Indian religion.
