Demographic statistics vary but they are in the same general range. History will likely never know how many people were interned or died there, due to periods of disruption. One source gives a general estimate of over 200,000 prisoners from more than 30 countries for the Third Reich's years, of whom two-thirds were political prisoners, including many Catholic priests, and nearly one-third were Jews. 25,613 prisoners are believed to have died in the camp and almost another 10,000 in its subcamps,[16] primarily from disease, malnutrition and suicide. In late 1944, a typhus epidemic occurred in the camp caused by poor sanitation and overcrowding, which caused more than 15,000 deaths.[17] It was followed by an evacuation, in which large numbers of the prisoners died. Toward the end of the war, death marches to and from the camp caused the deaths of numerous unrecorded prisoners. After liberation, prisoners weakened beyond recovery by the starvation conditions continued to die.[18] Two thousand cases of "the dread black typhus" had already been identified by 3 May, and the U.S. Seventh Army was "working day and night to alleviate the appalling conditions at the camp".[19] Prisoners with typhus, a louse-borne disease with an incubation period from 12 to 18 days, were treated by the 116th Evacuation Hospital, while the 127th would be the general hospital for the other illnesses. There were 227 documented deaths among the 2,252 patients cared for by the 127th.[18]
The Summer Olympics in Berlin gave the Nazis a platform to project a crafted image to the world. Despite calls for boycotts, the games were a success. Anti-Jewish notices were removed and German spectators cheered black athlete Jesse Owens to four gold medals. Visitors saw a tolerant Reich. However, three days after the games ended, the head of the Olympic Village, Wolfgang Fürstner, killed himself as he would soon be dismissed due to his Jewish ancestry under the Nuremberg Laws.
Entering conquered Soviet territories alongside the Wehrmacht (the German armed forces) were 3,000 men of the Einsatzgruppen (“Deployment Groups”), special mobile killing units. Their task was to murder Jews, Soviet commissars, and Roma in the areas conquered by the army. Alone or with the help of local police, native anti-Semitic populations, and accompanying Axis troops, the Einsatzgruppen would enter a town, round up their victims, herd them to the outskirts of the town, and shoot them. They killed Jews in family units. Just outside Kiev, Ukraine, in the ravine of Babi Yar, an Einsatzgruppe killed 33,771 Jews on September 28–29, 1941. In the Rumbula Forest outside the ghetto in Riga, Latvia, 25,000–28,000 Jews were shot on November 30 and December 8–9. Beginning in the summer of 1941, Einsatzgruppen murdered more than 70,000 Jews at Ponary, outside Vilna (now Vilnius) in Lithuania. They slaughtered 9,000 Jews, half of them children, at the Ninth Fort, adjacent to Kovno (now Kaunas), Lithuania, on October 28.
The government defined a Jewish person as someone with three or four Jewish grandparents, not someone who had religious convictions. This meant that people who had never practiced, or hadn’t practiced Judaism in many years, or even converted to Christianity were subjected to persecution. Although anti-semitism was pervasive in 1930s Germany, these restrictions frequently extended to any person the Nazis considered to be “non-Aryan”.
Shortly after the outbreak of war in September 1939, thirty-one-year-old Schindler showed up in occupied Krakow. The ancient city, home to some 60,000 Jews and seat of the German occupation administration, the Generalgouvernement, proved highly attractive to German entrepreneurs, hoping to capitalize on the misfortunes of the subjugated country and make a fortune. Naturally cunning and none too scrupulous, Schindler appeared at first to thrive in these surroundings.  In October 1939, he took over a run-down enamelware factory that had previously belonged to a Jew.  He cleverly maneuvered his steps- acting upon the shrewd commercial advice of a Polish-Jewish accountant, Isaak Stern - and began to build himself a fortune. The small concern in Zablocie outside Krakow, which started producing kitchenware for the German army, began to grow by leaps and bounds. After only three months it already had a task-force of some 250 Polish workers, among them seven Jews. By the end of 1942, it had expanded into a mammoth enamel and ammunitions production plant, occupying some 45,000 square meters and employing almost 800 men and women. Of these, 370 were Jews from the Krakow ghetto, which the Germans had established after they entered the city.
These evacuations were regarded as provisional or "temporary solutions" ("Ausweichmöglichkeiten").[266][p] The final solution would encompass the 11 million Jews living not only in territories controlled by Germany, but elsewhere in Europe and adjacent territories, such as Britain, Ireland, Switzerland, Turkey, Sweden, Portugal, Spain, and Hungary, "dependent on military developments".[266] There was little doubt what the final solution was, writes Peter Longerich: "the Jews were to be annihilated by a combination of forced labour and mass murder".[268]
Hundreds of prisoners suffered and died, or were executed in medical experiments conducted at KZ Dachau, for which Sigmund Rascher was in charge. Hypothermia experiments involved exposure to vats of icy water or being strapped down naked outdoors in freezing temperatures. Attempts at reviving the subjects included scalding baths, and forcing naked women to copulate with the unconscious victim. Nearly 100 prisoners died during these experiments.[53] The original records of the experiments were destroyed "in an attempt to conceal the atrocities".[a][54]
That June, Theodor Eicke (1892-1943) replaced Wäckerle as Dachau commandant. Eicke immediately released a set of regulations for the camp’s daily operation. Prisoners deemed guilty of rule breaking were to be brutally beaten. Those who plotted to escape or espoused political views were to be executed on the spot. Prisoners would not be allowed to defend themselves or protest this treatment. Eicke’s regulations served as a blueprint for the operation of all concentration camps in Nazi Germany.
In the entire history of the Orthodox Church there has probably never been an Easter service like the one at Dachau in 1945. Greek and Serbian priests together with a Serbian deacon adorned the make-shift 'vestments' over their blue and gray-striped prisoners' uniforms. Then they began to chant, changing from Greek to Slavic, and then back again to Greek. The Easter Canon, the Easter Sticheras—everything was recited from memory. The Gospel—In the beginning was the Word—also from memory. And finally, the Homily of Saint John—also from memory. A young Greek monk from the Holy Mountain stood up in front of us and recited it with such infectious enthusiasm that we shall never forget him as long as we live. Saint John Chrysostomos himself seemed to speak through him to us and to the rest of the world as well!
In March 1944, part of the camp was redesignated as an Erholungslager ("recovery camp"),[11] where prisoners too sick to work were brought from other concentration camps. They were in Belsen supposedly to recover and then return to their original camps and resume work, but many of them died in Belsen of disease, starvation, exhaustion and lack of medical attention.[12]
