The early Aryans settled in the upper reaches of the Indus, Yamuna, and Gangetic plains. The Aryans settled there because the time of the Aryan arrival suggested that they play a role in the fall of the Harappan civilization. Later over time, the Aryan people and the people of the Indus River Vally produced a new blend of culture in northern Asia!
