Generalplan OstGeneralplan Ost was Nazi plan of establishing new order in territoriers occupied in the east during World War II, prepared in 1941 and confirmed in 1942. No written document survived, and plan can be only reconstructed from memos, abstracts and other Nazi documents. It was divided into Kleine planung which covered action which should be done during the war, and Grosse planung which should cover actions to do after the won war. The plan predicted which precentage of which nation should be germanised, which part should be expelled etc. It estimated that 51 millions of Slavs (Poles, Czechs, Russian, Belorusins etc) should be expelled behind the Ural. From Poles only about 3-4 million people were supposed to be left in former Poland and serve as slaves. Two special cases were Poles, who were generally suitable to germanised, but because of their patriotism destined of dispersion or extermination, and Russians. Generalplan Ost included also Endlosung der Judenfrage.
Main initiator of the plan was Heinrich Himmler. During the war Nazis started realisation the plan by expellings in Poland (Zamojszczyzna etc) and Ukraine.
Also operations such Operation Tannenberg (Unternehmen Tannenberg) and different Intelligenzaktion which included shootings of Polish intelligentsia and activists were made part of this plan.
