The final version of Generalplan Ost, essentially a grand plan for ethnic cleansing, was divided into two parts; the "Small Plan" (Kleine Planung), which covered actions which were to be taken during the war, and the "Big Plan" (Grosse Planung), which covered actions to be undertaken after the war was won, and to be implemented gradually over a period of 25 to 30 years.[7][10]
Percentages of ethnic groups targeted for elimination by Nazi Germany from future settlement areas[11][12]
Ethnic group Percentage subject to removal
Poles 80–85%
Russians 50–60% to be physically eliminated and another 15% to be sent to Western Siberia.
Belarusians 75%
Ukrainians 65%
Lithuanians 85%
Latvians 50%
Estonians 50%[13]
Czechs 50%
Latgalians 100%
Generalplan Ost envisaged differing percentages of the various conquered nations undergoing Germanization (for example, 50% of Czechs, 35% of Ukrainians and 25% of Belarusians), extermination, expulsion and other fates, the net effect of which would be to ensure that the conquered territories would be Germanized. In ten years' time, the plan effectively called for the extermination, expulsion, Germanization or enslavement of most or all East and West Slavs living behind the front lines in Europe.
