Any section of a town inhabited predominantly by members of a specific ethnic, national or racial group, such segregation usually arising from social or economic pressure. The term is commonly applied to areas in cities having a high concentration of low-income African-Americans.
The Nazis revived the medieval term 'ghetto' to describe their compulsory "Jewish quarters." Ghettos were poor sections of a city where all Jews from the city and surrounding areas were forced to reside. Surrounded by barbed wire or walls, the ghettos were sealed and no one could leave. Established mostly in German-occupied Eastern Europe (for example, Lodz, Warsaw, Vilna, Riga, Minsk), the ghettos were characterized by overcrowding, starvation and heavy labor. All ghettos were eventually dissolved, and the Jews and Gypsies that had resided there were deported and murdered.
