Ghettoan enclosed district where Jews were forced to live separate from the rest of society.
The concentration of Jews in ghettos was a policy implemented by Germany in Eastern Europe and the Soviet Union. The establishment of ghettos was often the first stage in a process which was followed by deportation to concentration camps and selection for extermination or for forced labor. Forcing Jews into ghettos required their ingathering from surrounding areas and their segregation from local populations.
