The idea for the expulsion and resettlement of the Jews of Europe,[1] into the remote corner of the Generalgouvernement territory bordering the cities of Lublin and Nisko, was devised by Adolf Hitler and formulated by his SS henchmen. The plan was developed in September 1939 after the invasion of Poland and implemented between October 1939 and April 1940, in contrast to similar Nazi "Madagascar" and other Jewish relocation plans drawn up before the attack on Poland at the beginning of World War II.[2][3][4]
