Answer:
Hitler built concentration camps in Auschwitz and Dachau.
Explanation:
Between 1933 and 1945, the Nazi regime concentration camps for the detention of persons who were considered to threaten the security of the kingdom or the purity of the German race. The camps were run by the SS under the leadership of Heinrich Himmler.
The first camp was set up during Hitler's takeover of power in 1933, when several thousand politically oppositionists were interned. Over the next four years, there were about six concentration camps with a total of between 4,000 and 7,750 prisoners. In 1937, the camp system grew and escalated during the last years of the war. The biggest change occurred in 1942 when the camps became part of the war economy and began to supply labor to the industry. At the same time, mass murders of Jews in the Dachau and Auschwitz camps began.
In January 1945, there were about 730 camps and more than 700,000 prisoners. The huge expansion of the camp system in terms of both the number of camps and the number of prisoners was a consequence of the Germans' need for labor for the war industry and the ideological goal of exterminating the Jews of Europe.
About 1,650,000 people were sent to concentration camps between 1933 and 1945, of whom more than a million died. [4] [5] To this number can be added the more than one million Jews who were brought and executed in the extermination facilities in the Majdanek and Auschwitz camps. (The victims in the extermination camps Sobibór, Bełżec, Treblinka and Chełmno are not included here.)
The term concentration camps (German: concentration camps) had been borrowed by the Germans from the concentration camps the English established in South Africa during the Boer War of 1879-1915. In Nazi Germany, only formally the camps belonging to the SS authority were the Inspectorate for Concentration Camps, which was designated Concentration Camps. There were also a number of other detention and labor camps, but they had other names.
The German word Concentration layer is abbreviated KZ or KL.
