The town of Lublin in Poland had been the focus of Nazi planners since the early 1930s, after Herrmann Seiffert described it as the center of Jewish worldwide power and source of their genetic potential.[9] After Nazi Germany had defeated Poland in September 1939 and partitioned her with the Soviet Union, the Lublin area became part of the Generalgouvernement headed by Hans Frank.[10] Once under Nazi German control, the area was inspected by Frank's deputy Artur Seyss-Inquart in November 1939.
