The Nazis issued the Polish decrees on 8 March 1940 which regulated the working and living conditions of Polish laborers (Zivilarbeiter) used during World War II in Germany. The decrees set out that any Pole "who has sexual relations with a German man or woman, or approaches them in any other improper manner, will be punished by death." The Gestapo were extremely vigilant about sexual relations between Germans and Poles and pursued any case relentlessly where this was suspected. There were similar regulations used against the other ethnic groups brought in from Eastern Europe, including the death penalty for sexual relations with a German person. During the war, hundreds of Polish and Russian men were executed for their relations with German women.
