Indo-Aryan migration
The Indo-Aryan migration into the northern Punjab started shortly after the decline of the Indus Valley Civilisation (IVC). According to the "Aryan Invasion Theory" this decline was caused by "invasions" of barbaric and violent Aryans who conquered the IVC. This "Aryan Invasion Theory" is not supported by the archeological and genetic data, and is not representative of the "Indo-Aryan migration theory".
