Has genocide ever wiped out an entire race?

Answer 1

No.

While it is hard to say that a specific genocide managed to wipe out every last member of some group, genocidal campaigns have managed to effectively destroy entire races. By this, I mean that enough members of the race were killed to destroy any culture that race had, and the few remaining members eventually were absorbed into other cultures, losing their distinctiveness.

This later situation has occurred frequently throughout human history. A good example in the United States is the practical genocide attempted on the American Indian tribes in the 1800s. A fair number of tribes have now completely disappeared - the sole remaining members who survived the genocidal campaigns were either absorbed into neighboring tribes, or entered the White Man's world, and lost their Indian heritage. More recently, the Holocaust managed to kill virtually all the Polish Jews (down from a pre-war population of 3+million to less than 200,000 post-war) to such an extent that virtually all those remaining immigrated to Israel, effectively destroying Polish Jewish culture.
