 In 1941 , German policy evolved further , calling for the complete destruction of the Polish people , whom the Nazis regarded as " subhumans " ( Untermenschen ) . Within ten to twenty years , the Polish territories under German occupation were to be entirely cleared of ethnic Poles and settled by German colonists . The policy was relaxed somewhat in the final years of occupation ( 1943 – 44 ) , in view of German military defeats and the approaching Eastern Front . The Germans hoped that a more lenient cultural policy would lessen unrest and weaken the Polish Resistance . Poles were allowed back into those museums that now supported German propaganda and indoctrination , such as the newly created Chopin museum , which emphasized the composer 's invented German roots . Restrictions on education , theater and music performances were eased .
