The truth of the Holocaust photos and pictures of Nazi crimes and atrocities included in this project needs to be shown. The Holocaust photos may be of graphic nature and disturbing - before providing access to younger learners, parents and teachers should preview the sites and guide through what they may read and see.

The Holocaust was the systematic annihilation of six million Jews during the Nazi genocide - in 1933 nine million Jews lived in the 21 countries of Europe that would be occupied by Nazi Germany during World War 2. By 1945 two out of every three European Jews had been killed.

The number of children killed by the Nazis is not fathomable and full statistics for the tragic fate of the children will never be known. Estimates range as high as 1.5 million murdered children during the Holocaust. This figure includes more than 1.2 million Jewish children, tens of thousands of Gypsy children and thousands of institutionalized handicapped children.

Plucked from their homes and stripped of their childhoods, the children had witnessed the murder of parents, siblings, and relatives. They faced starvation, illness and brutal labor, until they were consigned to the gas chambers.
