Collaboration in German-occupied Poland

During the German occupation of Poland, citizens of all its major ethnic groups collaborated with the Germans. Estimates of the number of collaborators vary. Collaboration in Poland was less institutionalized than in some other countries and has been described as marginal, a point of pride with the Polish people. During and after the war, the Polish government in exile (a member of the Allied coalition that fought Nazi Germany) and the Polish resistance movement punished collaborators and sentenced thousands of them to death.
