In the context of the murder of about six million European Jews, the lives of Jewish children in concentration camps were essentially reduced to their survival, unintended by the regime and under inhumane conditions, for a certain period of time.

We will investigate, among other things, the reasons for the registration of Jewish children in the concentration camps in the context of the genocide perpetrated against the Jews, which camps contained groups of Jewish children, and the nature of their lives and living conditions in the camps.
