Jews resisted the Nazis in many ways. Even in the ghettos and camps many managed to preserve their cultural and religious identity. They maintained schools and prayer groups. Others organised cultural and artistic groups. There are many examples of this kind of resistance.
In the Vilna ghetto, they managed to maintain an underground lending library. In the Warsaw ghetto a great teacher, Janusz Korczak, set up an orphanage. He taught the children, organised plays for them and tried to make their lives as normal as possible. He even accompanied them to their deaths in Treblinka so that they should not be frightened of the dark.
Many people wanted the world to know what was happening and kept diaries. One person hid his diaries in six milk churns in Warsaw; five of them were discovered after the war and the diaries were published.
Other forms of unarmed resistance were common within the ghettos. The smuggling of food was mainly carried out by the young. It was a form of resistance that was significant as it enabled people to eat and therefore survive.
