During World War II, Nazi birthing centres for foreign workers, known in German as Ausländerkinder-Pflegestätte, Ostarbeiterkinderpflegestätten, or Säuglingsheim were German institutions used as stations for abandoned infants, Nazi Party facilities established in the heartland of Nazi Germany for the so-called 'troublesome' babies according to Himmler's decree, the offspring born to foreign women and girls servicing the German war economy, including Polish and Eastern European female forced labour. The babies and children, most of them resulting from rape at the place of enslavement, were abducted en masse between 1943 and 1945. At some locations, up to 90 percent of infants died a torturous death due to calculated neglect.

Ostarbeiter was a Nazi German designation for foreign slave workers gathered from occupied Central and Eastern Europe to perform forced labor in Germany during World War II. The Germans started deporting civilians at the beginning of the war and began doing so at unprecedented levels following Operation Barbarossa in 1941. They apprehended Ostarbeiter from the newly-formed German districts of Reichskommissariat Ukraine, District of Galicia, and Reichskommissariat Ostland. These areas comprised German-occupied Poland and the conquered territories of the Soviet Union. According to Pavel Polian, although the Ostarbeiter from most occupied territories were predominantly men, of the "eastern workers" taken from occupied Soviet territories over 50% were women, and of those from Poland nearly 30% were women. Eastern workers included ethnic Ukrainians, Poles, Belarusians, Russians, Armenians, Tatars, and others. Estimates of the number of Ostarbeiter range between 3 million and 5.5 million.
