After ww11 began Jewish people were taken into custody and placed where?

They were put into concentration camps. the american pows were put into work/prison camps very similar to concentration camps.

The word "Holocaust," from the Greek words "holos" (whole) and "kaustos" (burned), was historically used to describe a sacrificial offering burned on an altar. Since 1945, the word has taken on a new and horrible meaning: the mass murder of some 6 million European Jews (as well as members of some other persecuted groups, such as Gypsies and homosexuals) by the German Nazi regime during the Second World War. To the anti-Semitic Nazi leader Adolf Hitler, Jews were an inferior race, an alien threat to German racial purity and community. After years of Nazi rule in Germany, during which Jews were consistently persecuted, Hitler's "final solution"-now known as the Holocaust-came to fruition under the cover of world war, with mass killing centers constructed in the concentration.
