Kristallnacht was the night of November 9th 1938. Most historians agree that it is the official beginning of the holocaust, it consisted of German soldiers destroying Jewish owned businesses and homes and attacking, and even killing innocent Jewish people.

during the holocaust and German expansion, more than 40,000 jewish concentration and death camps were built. they spanned from Russia all the way to the border of Spain.

Once jewish prisoners were transported from ghettos to camps they were sorted by age, fitness, and gender, their heads' were shaved, and they were given new clothes

Jews at this camp had the chance of forcefully being part of human experimentation, some of these consisted of the Nazi Twin Experiments. In these experiments mainly polish or romani twins aged from toddlers to elderly were brutally experimented on: these experiments were supervised by Eduard Wirths

German SS officer who was selected to oversee selection of prisoners, those he found fit to work were sent to the camps, those he found unfit for any reason were sent immediately to gas chambers, firing squad, or burning pits. He was also allowed to preform human experimentation although he was not a supervisor.

after being sorted and dressed, Jews would be sent to cold concrete rooms filled with poorly made beds that were little more than a plank of wood. prisoners were often only fed once a day or not at all, they worked long days, they either worked in factories or did meaningless labor used specifically to tire and weaken them.

starting on June 23, 1944, concentration camps began to be discovered and liberated. the first were discovered by Soviet soldiers on a march through German territory. these camps were usually abandoned by all personnel and officers leaving only the prisoners without food for multiple days at a time. the last camp was liberated on April 11th, 1945. many survivors wen ton to live into their 90s.
