Nazi crimes against the Polish nation
Crimes against the Polish nation committed by Nazi Germany and Axis collaborationist forces during the invasion of Poland, along with auxiliary battalions during the subsequent occupation of Poland in World War II, consisted of the murder of millions of ethnic Poles and the systematic extermination of Jewish Poles. The Germans justified these genocides on the basis of Nazi racial theory, which regarded Poles and other Slavic peoples as racially inferior "Untermenschen" and depicted Jews as a constant threat. By 1942, the Nazi Germans were implementing their plan to kill every Jew in German-occupied Europe, and had also developed plans to eliminate the Polish people through mass murder, ethnic cleansing, enslavement and extermination through labor, and assimilation into German identity of a small minority of Poles deemed "racially valuable". During World War II, the Germans not only murdered millions of Poles (Jewish and otherwise), but ethnically cleansed millions more through forced deportation to make room for “racially superior” German settlers (see Generalplan Ost and Lebensraum). The genocides claimed the lives of 2.7 to 3 million Polish Jews and 1.8 to 2.77 million non-Jewish ethnic Poles, according to various sources such as Poland's Institute of National Remembrance.
