generalplan ost (english: master plan for the east) was a secret nazi plan for the colonization and exploitation of eastern europe. the plan called for the extermination, expulsion, or enslavement of most of the slavic populations of eastern europe, including poland, ukraine, belarus, and the soviet union. the plan was part of the broader nazi goal of creating lebensraum (living space) for the aryan race.
the plan was developed by a group of nazi officials, led by heinrich himmler and including adolf eichmann and alfred rosenberg. it was presented to adolf hitler in 1941, and he gave his approval. however, the plan was never fully implemented due to the course of the war.
