Yugoslavia and Greece were invaded in April 1941 and surrendered before the end of the month. Germany and Italy divided Greece into occupation zones but did not eliminate it as a country. Yugoslavia, home to around 80,000 Jews, was dismembered; regions in the north were annexed by Germany and regions along the coast made part of Italy. The rest of the country was divided into the Independent State of Croatia, nominally an ally of Germany, and Serbia, which was governed by a combination of military and police administrators.[167] According to historian Jeremy Black, Serbia was declared free of Jews in August 1942.[168] Croatia's ruling party, the Ustashe, killed the country's Jews, and killed or expelled Orthodox Christian Serbs and Muslims.[167] Jews and Serbs alike were "hacked to death and burned in barns", according to Black. One difference between the Germans and Croatians was that the Ustashe allowed its Jewish and Serbian victims to convert to Catholicism so they could escape death.[168]

The photo above was taken while Mengele was home on leave, after spending 5 months at Auschwitz-Birkenau. He is wearing an Iron Cross medal on the pocket of his uniform. Mengele was very proud of his medals; he earned the Iron Cross 2nd Class shortly after he was sent to the Ukraine in June 1941 at the time of the German invasion of the Soviet Union. In January 1942, Mengele joined the prestigious 5th SS Panzer Division, nicknamed the Viking Division. In July 1942, he was awarded the Iron Cross 1st Class after he pulled two wounded soldiers out of a burning tank under enemy fire on the battlefield, and administered medical first aid to them.
Overnight on November 9-10, 1938, the Nazis incited a pogrom against Jews in Austria and Germany called Kristallnacht (Night of Broken Glass, or literally translated from German, "Crystal Night"). This included the pillaging and burning of synagogues, the breaking of windows of Jewish-owned businesses and the looting of those stores. In the morning, broken glass littered the ground. Many Jews were physically attacked or harassed, and approximately 30,000 were arrested and sent to concentration camps.
Historians disagree as to when and how the Nazi leadership decided that the European Jews should be exterminated. The controversy is commonly described as the functionalism versus intentionalism debate which began in the 1960s, and subsided thirty years later. In the 1990s, the attention of mainstream historians moved away from the question of top executive orders triggering the Holocaust, and focused on factors which were overlooked earlier, such as personal initiative and ingenuity of countless functionaries in charge of the killing fields. No written evidence of Hitler ordering the Final Solution has ever been found to serve as a "smoking gun", and therefore, this one particular question remains unanswered.[105]
There is no postwar institution specializing in either World War II or the Holocaust that has collected systematic data about the righteous or about Christian-Jewish relations during the war years. Postwar historiography has given scant attention to this subject, except for biographies of heroes like Raoul Wallenberg in Budapest. Individual episodes are recorded in numerous published memoirs or hidden within the histories of the Jewish communities under German occupation. Others are found in some survivor testimonies, oral histories, and depositions.
On October 23, 1941, S.S. head Heinrich Himmler issued an order down the Nazi chain of command which heralded a major change in Nazi policy with respect to the “Jewish problem.” Until then, the Nazis worked vigorously to encourage Jews to emigrate. The Madagascar Plan (see below) was one example of strategies which were formulated to remove Jews from Germany and its occupied lands. As is described in more detail in Chapter 11, many countries refused to accept Jewish refugees. This shift in policy resulted in the deportation of Jews to camps and ghettos in the East. The policy to “resettle” Jews to these ghettos and camps was a significant step in what was to become the “Final Solution” the systematic murder of millions of Jews.
Dr. Josef Mengele, nicknamed The Angel Of Death, and the other Nazi doctors at the death camps tortured men, women and children and did medical experiments of unspeakable horror during the Holocaust. Victims were put into pressure chambers, tested with drugs, castrated, frozen to death. Children were exposed to experimental surgeries performed without anesthesia, transfusions of blood from one to another, isolation endurance, reaction to various stimuli. The doctors made injections with lethal germs, sex change operations, removal of organs and limbs.
On November 12, 1938, Field Marshal Hermann Göring convened a meeting of Nazi officials to discuss the damage to the German economy from pogroms. The Jewish community was fined one billion Reichsmarks. Moreover, Jews were made responsible for cleaning up the damage. German Jews, but not foreign Jews, were barred from collecting insurance. In addition, Jews were soon denied entry to theatres, forced to travel in separate compartments on trains, and excluded from German schools. These new restrictions were added to earlier prohibitions, such as those barring Jews from earning university degrees, from owning businesses, or from practicing law or medicine in the service of non-Jews. The Nazis would continue to confiscate Jewish property in a program called “Aryanization.” Göring concluded the November meeting with a note of irony: “I would not like to be a Jew in Germany!”
A major tool of the Nazis' propaganda assault was the weekly Nazi newspaper Der Stürmer (The Attacker). At the bottom of the front page of each issue, in bold letters, the paper proclaimed, "The Jews are our misfortune!" Der Stürmer also regularly featured cartoons of Jews in which they were caricatured as hooked-nosed and ape­like. The influence of the newspaper was far-reaching: by 1938 about a half million copies were distributed weekly.
Of the eight people in the secret annex, only Otto Frank survived the war. He subsequently returned to Amsterdam, where Gies gave him various documents she had saved from the annex. Among the papers was Anne’s diary, though some of the notebooks were missing, notably most of those from 1943. To fulfill Anne’s dream of publication, Otto began sorting through her writings. The original red-and-white checkered journal became known as the “A” version, while her revised entries, written on loose sheets of paper, were known as the “B” version. The diary that Otto ultimately compiled was the “C” version, which omitted approximately 30 percent of her entries. Much of the excluded text was sexual-related or concerned Anne’s difficulties with her mother.
According to psychologist Eva Fogelman “Rescuers’ families nourished an independence of mind and spirit. … In talking with rescuers from all kinds of different homes, I found that one quality above all others was emphasized time and again: a familial acceptance of people who were different. This value was the centrepiece of the childhood of rescuers and became the core from which their rescuer self evolved. From the earliest ages, rescuers were taught by their parents that people are inextricably linked to one another. No one person or group was better than any other. The conviction that all people, no matter how marginal, are of equal value was conveyed to children of both religious and nonreligious households.” Fogelman is the daughter of a Holocaust survivor and founder of the Jewish Foundation for Christian Rescuers.
Which made him all the more intrigued to hear, two years ago, about a new research project led by Jon Seligman, of the Israel Antiquities Authority, at the site of Vilnius’s Great Synagogue, a once towering Renaissance-Baroque structure dating to the 1630s. The synagogue, which had also housed a vast library, kosher meat stalls and a communal well, had at one time been the crown jewel of the city, itself a center of Jewish life in Eastern Europe—the “Jerusalem of the North.” By one estimate, at the turn of the 20th century Vilnius was home to some 200,000 people, half of them Jewish. But the synagogue was damaged after Hitler’s army captured the city in June 1941 and herded the Jewish population into a pair of walled ghettos, whom it then sent, in successive waves, to Ponar. After the war the Soviets razed the synagogue entirely; today an elementary school stands in its place.
Mengele used Auschwitz as an opportunity to continue his anthropological studies and research into heredity, using inmates for human experimentation.[2] His medical procedures showed no consideration for the health, safety, or physical and emotional suffering of the victims.[2][3] He was particularly interested in identical twins, people with heterochromia iridum (eyes of two different colors), dwarfs, and people with physical abnormalities.[2] A grant was provided by the Deutsche Forschungsgemeinschaft (German Research Foundation), at the request of von Verschuer, who received regular reports and shipments of specimens from Mengele. The grant was used to build a pathology laboratory attached to Crematorium II at Auschwitz II-Birkenau.[38] Dr. Miklós Nyiszli, a Hungarian Jewish pathologist who arrived in Auschwitz on 29 May 1944, performed dissections and prepared specimens for shipment in this laboratory.[39] The twin research was in part intended to prove the supremacy of heredity over environment and thus strengthen the Nazi premise of the superiority of the Aryan race.[40] Nyiszli and others reported that the twin studies may also have been motivated by an intention to increase the reproduction rate of the German race by improving the chances of racially desirable people having twins.[41]
