The ghettos established during the Holocaust and survivors from them. The Nazis established them because they wanted to create total confinement of the Jews from the rest of the area. They thought ghettos would deplete the Jewish population quickly and naturally through starvation, disease, and cold. The ghettos were surrounded by barb wire or brick walls from which the Jews couldn't exit without authorization. The inhabitants of the ghettos were like slaves. Factories were built, so the Jews worked for free.

The Jews living conditions were terrible. There was one toilet for almost every 2,000 persons. Nazis wouldn't let the inhabitants empty sewage and waste. The typhus epedimic ran wild. The hospital was merely a hospital. They had no medicine, stethoscopes, and only makeshift beds. Most people had poor nurishment, lack of vitamins, lack of fresh air and exercise. Most people hallucinated and anticipated misfortune and worried.
