Poles were viewed by Nazis as subhuman non-Aryans, and during the German occupation of Poland 2.7 million ethnic Poles died. Polish civilians were subject to forced labour in German industry, internment, wholesale expulsions to make way for German colonists, and mass executions. The German authorities engaged in a systematic effort to destroy Polish culture and national identity. During operation AB-Aktion, many university professors and members of the Polish intelligentsia were arrested, transported to concentration camps, or executed. During the war, Poland lost an estimated 39 to 45 per cent of its physicians and dentists, 26 to 57 per cent of its lawyers, 15 to 30 per cent of its teachers, 30 to 40 per cent of its scientists and university professors, and 18 to 28 per cent of its clergy.
