The Generalplan Ost, abbreviated GPO, was Nazi Germany's blueprint for the genocide, extermination and large-scale ethnic cleansing of Slavs, Eastern European Jews, and other indigenous peoples of Eastern Europe categorized as "Untermensch" in Nazi ideology. The campaign was a precursor to Nazi Germany's planned colonisation of Central and Eastern Europe by Germanic settlers, and it was carried out through systematic massacres, mass starvations, chattel labour, mass-rapes, child abductions, and sexual slavery.
Prisoners of the Krychów forced labor camp dig irrigation ditches for the new German latifundia of the General Plan East in 1940. Most of them, Polish Jews and some Roma people, were sent to Sobibór extermination camp afterwards.
