The Aryans were a fair skinned people that originated somewhere near the Caspian and Black Sea around 1500 B.C. The Aryan people possessed greater technologies than many of the peoples around them. For many hundreds of years the Aryans spread from the region near these two seas towards the Indus River Valley.
After conquering the peoples of the Indus River Valley, the Aryans continued to push their territory outward. They moved towards the southeast, and conquered the people of the Ganges Plain.
The Aryan culture eventually spread throughout much of South Asia. Many aspects of Aryan culture still exist in these regions today.
Be able to be alone. Lose not the advantage of solitude.
