In the first years of the Second World War, German policy in relation to the "Jewish question" in occupied Poland was not coherent and consistent. Nevertheless, its fundamental aim was to isolate Jews, loot their property, exploit them through forced labour and, in the final stage, remove them completely from the land under the authority of the Third Reich. An initial plan for dealing with the Jewish population in Poland was adopted already on September 21, 1939, i. e. before the end of the September campaign. On that day, a meeting was held in Berlin led by SS-Gruppenführer Reinhard Heydrich, attended by the chief heads of the main departments of the General Security Police Office and commander of Einsatzgruppen operating in Poland. It was then established that all Jews living in the lands, which were to be incorporated into the Reich, would be resettled in central Poland. Mass deportations were to be preceded by removal of the Jewish population from rural areas and its concentration in larger urban centers. In the remaining occupied areas, it was also intended to forcibly resettle Jews to larger towns, especially to those located near railway lines. Moreover, during the meeting, a number of recommendations were adopted, including the creation of "Jewish Elder Councils", the establishment of a census of the Jewish population, as well as its marking and taking up forced labor.
