In post-1945 Germany and Austria the concept of Germanisation is no longer considered relevant. By the loss of the Former eastern territories of Germany and the Polonisation of these regions, and the Expulsion of Germans from Czechoslovakia most of the regions that had been subject of medieval Ostsiedlung ceased being part of German-speaking Europe. German-speaking minorities continue to exist in Eastern Europe, such as in Opole Voivodeship or in Romania and are being supported by the German Federal Government.
