Jewish ghettos were sections of cities where Jewish people were forced to live, especially during the Middle Ages and the Nazi era. These areas were often overcrowded and isolated from the rest of society, with limited access to resources and basic services. The establishment of ghettos aimed to segregate Jewish communities and restrict their freedoms. During the Holocaust, ghettos became a means of controlling and persecuting Jewish populations. Many were subjected to harsh living conditions, starvation, and violence. Some notable ghettos included the Warsaw Ghetto and the Lodz Ghetto, where thousands suffered before being deported to concentration camps.
