 In West Germany, Brandt's "Neue Ostpolitik" was extremely controversial, dividing the populace into two camps.One camp embraced all of the conservative parties, and most notably those West German residents and their families who had been driven west ("die Heimatvertriebenen") by Stalinist ethnic cleansing from Historical Eastern Germany, especially the part that was given to Poland as a consequence of the end of the war; western Czechoslovakia (the Sudetenland); and the rest of Eastern Europe, such as in Romania.These groups of displaced Germans and their descendants loudly voiced their opposition to Brandt's policy, calling it "illegal" and "high treason".
