Poznan was located in Warthegau, a territory established by the Germans in October 1939 in the western part of Poland. It was incorporated into the Reich. More than 70,000 ethnic Poles were murdered there, others were sent to forced labor and Concentration Camps, while other Poles were persecuted by confiscation of Polish property, meager food rations, restriction of movement, closure of schools, and a ban on Polish language and culture. Warthegau was run by Arthur Greiser the Reich Governor of the territory. He was one of the Nazis primarily responsible for organizing the Holocaust in occupied Poland and numerous other crimes against humanity. He was arrested by the Americans in 1945, tried, convicted and executed by hanging in Poland in 1946.
