Indian is probably the most indigenously racially diverse nation on earth.
My point is that those races are primarily unique to you and within you're own borders. Apart from say to some extent bangladesh or Sri Lanka there are no other nations on earth that have the majority of their population made up by an indigenous india race. In Europe the reverse is true. Although there are many different nations and small cultural variations in Europe, all European nations are made up of one race, the White European race. Most Arab nations are made up the Arabic race. In the case of European and Arabic nations: 1 race, one people, one religion and heritage. In the case of india: many races, many cultures but 1 nation.
