Let me tell you a secret ,
the Region you claim ur Region was the region we Hindu crossed several thousand years backs to arrive Indian hinterlands . So what you call as your region was our region till it fell to the ARab and central asian muslim invaders and you people converted to islam .
Even the DNA studies say overwhelming majority of Indians are descended from two ancient populations, Ancestral South Indians (ASI) and Ancestral North Indians (ANI), who, respectively, came to the subcontinent 65,000 and 45,000 years ago.
Ancestral North Indians (ANI) were the people who came to live in the lands you call as your region 45,000 years ago.
Indians are one people descended from two tribes
