There were two types of camps under the Nazi's rule. The slave labor concentration camps where inmates
were placed under harsh working conditions and starvation. The others were the actual death camps whose sole purpose was for
the annihilation of the Jewish population and any other "enemy" of the Nazis.
Between 1933 and 1936 thousands of people mostly political prisoners, German Gypsies and Jehovah's
Witnesses were sent to concentration camps. But it was not until after Kristallnacht, that 30,000 Jewish men were deported
to Dachau and other concentration camps.
On September 1, 1939 Germany invaded Poland and World War II began. Thousands of Poles including Jews
were imprisoned in concentration camps. As the War began in 1939 Hitler ordered the killing of institutionalized, handicapped
patients deemed "incurable". After public protest the Nazi continued the "euthanasia" program in secret. The euthanasia
program contained all the elements later required for mass murder of Jews and Gypsies in Nazi death camps.
In the months following the invasion of the Soviet Union, Jews, and political leaders, Communists,
and Gypsies were killed in mass executions. During the war many new camps were built to accommodate the need for more space.
Between 1942 and 1944 the Germans moved to eliminate the ghettos in occupied Poland and elsewhere deporting ghetto residents
to death camps to be millions of Jews murdered through the death camps and poor living conditions that they faced
