Ghettos in Occupied Poland

Millions of Jews lived in eastern Europe. After Germany invaded Poland in 1939, more than two million Polish Jews came under German control. After Germany invaded the Soviet Union in June 1941, several million more Jews came under Nazi rule. The Germans aimed to control this sizable Jewish population by forcing Jews to reside in marked-off sections of towns and cities the Nazis called "ghettos" or "Jewish residential quarters." Altogether, the Germans created at least 1,000 ghettos in occupied territories. The largest ghetto was in Warsaw, the Polish capital, where almost half a million Jews were confined.

Many ghettos were set up in cities and towns where Jews were already concentrated. Jews as well as some Roma (Gypsies) were also brought to ghettos from surrounding regions and from western Europe. Between October and December 1941, thousands of German and Austrian Jews were transported to ghettos in eastern Europe. The Germans usually marked off the oldest, most run-down sections of cities for the ghettos. They sometimes had to evict non-Jewish residents from the buildings to make room for Jewish families. Many of the ghettos were enclosed by barbed-wire fences or walls, with entrances guarded by local and German police and SS members. During curfew hours at night the residents were forced to stay inside their apartments.

In the Polish cities of Łódź and Warsaw, trolley lines ran through the middle of the ghetto. Rather than reroute the lines, workers fenced them off, and policemen guarded the area to keep the Jews from escaping on the trolley cars. The passengers from outside the ghetto used the cars to get to work on weekdays, and some rode them on Sunday outings just to gawk and sneer at the ghetto prisoners.
