India's Northern region is a rich land which has attracted invaders from Central Europe & Asia who left their imprint on this land, its lifestyles over 40 centuries. The Greeks, under Alexander the Great, travelled as far down as the lower Indus River which they mispronounced as the "Hindu River", Consequently, all the various invaders, with their conflicting faiths, who inhabited the land of the Indus River were called Hindus & their land, Hindustan. It was shortened to "Hind", then "Ind" and finally, India.
