Approximately 9.9 million adults and 1.1 million children died during the holocaust. Six million Jews, almost two-thirds of the Jewish population of Europe at the time, were killed.
Between 1933 and 1945, the Nazi party constructed six camps specifically designed to kill people whom Hitler deemed "undesirable." The largest of these extermination camps, Auschwitz, claimed over a million victims. Although designed for detainment rather than execution, conditions in concentration camps were often fatal as well. These camps forced detainees to do heavy labor for long hours with little to no food, frequently resulting in death by starvation. Other prisoners died due to disease, torture and medical experimentation.
