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

But Jews were not the only group singled out for persecution by Hitler’s Nazi regime. As many as one-half million Gypsies, at least 250,000 mentally or physically disabled persons, and more than three million Soviet prisoners-of-war also fell victim to Nazi genocide. Jehovah’s Witnesses, homosexuals, Social Democrats, Communists, partisans, trade unionists, Polish intelligentsia and other undesirables were also victims of the hate and aggression carried out by the Nazis.

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

The world outside Nazi Europe received numerous press reports in the 1930s about the persecution of Jews. By 1942 the governments of the United States and Great Britain had confirmed reports about the Final Solution - Germany's intent to kill all the Jews of Europe. However, influenced by anti-Semitism and fear of a massive influx of refugees, neither country modified their refugee politics. No specific attempts to stop or slow the genocide were made until mounting pressure eventually forced the United States to undertake limited rescue efforts in 1944.

In Europe, rampant anti-Semitism incited citizens of many German-occupied countries to collaborate with the Nazis in their genocidal policies. There were, however, individuals and groups in every occupied nation who, at great personal risk, helped hide those targeted by the Nazis.

One nation, Denmark, saved most of its Jews in a nighttime rescue operation in 1943 in which Jews were ferried in fishing boats to safety in neutral Sweden.
