Final answer:
The enormous loss of life in Nazi extermination camps during World War II was motivated by Hitler's genocidal policies and the Nazis' belief in racial superiority. These camps were specifically designed for efficient mass murder and were discovered by the Allies during the liberation. The Holocaust ended with the end of the war.
Step-by-step explanation:
The enormous loss of life that occurred in Nazi extermination camps during World War II was motivated by Hitler's genocidal policies and his desire to create a Nazi-ruled Europe. The Nazis believed in the ideology of racial superiority and viewed certain groups of people, such as Jews, as racially, ideologically, or biologically 'unfit' to live in their vision of a master race.
Hitler and his regime implemented various methods of mass murder in the extermination camps, including gas chambers, crematoriums, and medical experiments. These camps, such as Auschwitz-Birkenau and Treblinka, were specifically designed to efficiently kill people and were located in Polish territory to hide them from major population centers.
Ultimately, the Holocaust ended because the war ended, and the Nazis could no longer continue their genocidal practices. The liberation of the camps by the Allies, such as Russian and American troops, exposed the full extent of the Holocaust and the systematic murder of millions of civilians, including six million Jews.
