Concurrent with annexations were the beginnings of attempts to ethnically cleanse non-Germans both from Germany and from the areas intended to be part of a "Greater Germany". Alternately, Hitler also made attempts to Germanize those who were considered ethnically or racially close enough to Germans to be "worth keeping" as part of a future German nation, such as the population of Luxembourg (officially, Germany considered these populations to actually be German, but not part of the Greater German Reich, and were thus the targets of propaganda promoting this view in order to integrate them). These attempts were largely unpopular with the targets of the Germanization, and the citizens of Luxembourg voted in a 1941 referendum up to 97% against becoming citizens of Nazi Germany.[8]
