There are plenty of examples from history where the winners simply wiped out the losers. In ancient times the usual practice was to kill all the men, take the women and children as slaves, and destroy all the cultural artifacts. Probably thousands of societies or cultures worldwide were utterly erased in that way, maybe leaving only some shards of pottery. We are perhaps a little more civilized about such things now, and show restraint for political or moral purposes rather than setting out to commit genocide.
