A Jewish ghetto is a section of a city where Jewish people were historically required to live, often due to legal restrictions or social discrimination. These areas were typically overcrowded and impoverished, with limited access to resources and opportunities. The term became widely used during the Middle Ages and was notably prominent during the Nazi regime in World War II. The most infamous example is the Warsaw Ghetto in Poland, where hundreds of thousands of Jews were confined under dire conditions. Ghettos served as a means of segregation, isolating Jewish communities from the rest of society and often leading to tragic consequences, including deportation and extermination.
