During World War II the Nazis created Jewish ghettos for the purpose of isolating, exploiting and finally eradicating Jewish population (and sometimes Romani people) on territories they controlled.

In total, according to United States Holocaust Memorial Museum archives, "The Germans established at least 1,000 ghettos in German-occupied and annexed Poland and the Soviet Union alone."

Therefore, the examples are intended only to illustrate their scope across Eastern and Western Europe.

These ghettos were liquidated as Holocaust transports delivered their helpless victims to concentration and extermination camps built by Nazi Germany in occupied Poland.

[1] Following the 1939 Invasion of Poland, the new ghetto system had been imposed by Nazi Germany roughly between October 1939 and July 1942 in order to confine Poland's Jewish population of 3.5 million for the purpose of persecution, terror, and exploitation.
