Below are figures for the number of Jews murdered in each country that came under German domination. They are estimates, as are all figures relating to Holocaust victims. The numbers given here for Czechoslovakia, Hungary and Romania are based on their territorial borders before the 1938 Munich agreement. The total number of six million Jews murdered during the Holocaust, which emerged from the Nuremberg trials, is also an estimate. Numbers have ranged between five and seven million killed.

Many Jews attempted to flee Germany, and thousands succeeded by immigrating to such countries as Belgium, Czechoslovakia, England, France and Holland. It was much more difficult to get out of Europe. Jews encountered stiff immigration quotas in most of the world's countries. Even if they obtained the necessary documents, they often had to wait months or years before leaving. Many families out of desperation sent their children first.

Anne Frank faced the threat of discovery and death every day while living in the Secret Annex. Despite terrible circumstances, however, her strength of spirit comes through in her diary. "...I still believe, in spite of everything," she wrote while in hiding, "that people are truly good at heart." Anne was one of millions of people during the Holocaust who found the courage to get through each day. Discover other Stories of Courage, and write about what you learn.
The SS used Sonderkommandos (Jewish slave laborers) during the gassing process to usher people in the undressing room and to clean up the gas chamber afterwards. One such survivor recalled the scene at Auschwitz: "There were all sorts of reactions from all sorts of people. There were disabled people. They would take out their war service cards showing that they had fought in the First World War with all kinds of distinctions and medals which they had from that time. They shouted, what's this? We fought for Germany. Now they're going to burn us, to kill us. This is impossible. We protest against such a thing. But everyone just laughed at them. Because they didn't take it seriously, these SS men. They laughed at the whole thing."
The theme for Holocaust Memorial Day 2015 is “keep the memory alive”, and today we want to remember Annelies Marie Frank, better known as Anne Frank, who started her diary Diary of a Young Girl at the age of just 13, while hiding from the German occupation of Amsterdam during the second world war. Anne wrote her diary in hiding in a secret annex of an old warehouse for the next two years. The diary stops abruptly in August 1944, when her family are betrayed and eventually sent to Auschwitz death camp. Only Anne’s father Otto survived and published his daughter’s Anne’s diary in 1947.
Despite, wide reporting of Holocaust atrocities including gas chambers, many prominent analysts doubted the authenticity of these reports. Prominently, Roger Allen, a member of the British Foreign Office discounted intelligence reports on the use of gas chambers in Polish extermination camps because he could “never understand what the advantage of a gas chamber over a simple machine gun or over starving people would be.”
A memorandum dated July 31, 1941, from Hitler’s top commander Hermann Goering to Reinhard Heydrich, chief of the SD (the security service of the SS), referred to the need for an Endlösung (final solution) to “the Jewish question.” Beginning in September 1941, every person designated as a Jew in German-held territory was marked with a yellow star, making them open targets. Tens of thousands were soon being deported to the Polish ghettoes and German-occupied cities in the USSR.
If Anne Frank had not perished in the criminal malevolence of Bergen-Belsen early in 1945, she would have marked her sixty-eighth birthday last June. And even if she had not kept the extraordinary diary through which we know her it is likely that we would number her among the famous of this century—though perhaps not so dramatically as we do now. She was born to be a writer. At thirteen, she felt her power; at fifteen, she was in command of it. It is easy to imagine—had she been allowed to live—a long row of novels and essays spilling from her fluent and ripening pen. We can be certain (as certain as one can be of anything hypothetical) that her mature prose would today be noted for its wit and acuity, and almost as certain that the trajectory of her work would be closer to that of Nadine Gordimer, say, than to that of Francoise Sagan. As an international literary presence, she would be thick rather than thin. “I want to go on living even after my death!” she exclaimed in the spring of 1944.
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”.

The deportations ... were the work of a much larger apparatus that had to deal with a host of constraints and requirements. The effort, as we shall see, was deemed necessary to accomplish the Final Solution on a European-wide scale.[p.273]

Dr. Mengele was nicknamed the "Angel of Death" by the prisoners because he had the face of an angel, yet he callously made selections for the gas chambers at Birkenau. He was nice to the children in the camp, yet he experimented on them as though they were laboratory rats. He volunteered to do the selections at Birkenau, even when it wasn't his turn, because he wanted to find subjects for his medical research on genetic conditions and hereditary diseases, which he had already begun before the war. He particularly wanted to find twins for the research that he had started before he was posted to Birkenau.

Dan Stone, a specialist in the historiography of the Holocaust, lists ethnic Poles, Ukrainians, Soviet prisoners of war, Jehovah's Witnesses, black Germans, and homosexuals as among the groups persecuted by the Nazis; he writes that the occupation of eastern Europe can also be viewed as genocidal. But the German attitude toward the Jews was different in kind, he argues. The Nazis regarded the Jews not as racially inferior, deviant, or enemy nationals, as they did other groups, but as a "Gegenrasse: a 'counter-race', that is to say, not really human at all". The Holocaust, for Stone, is therefore defined as the genocide of the Jews, although he argues that it cannot be "properly historically situated without understanding the 'Nazi empire' with its grandiose demographic plans".[d] Donald Niewyk and Francis Nicosia, in The Columbia Guide to the Holocaust (2000), favour a definition that focuses on the Jews, Roma, and Aktion T4 victims: "The Holocaust—that is, Nazi genocide—was the systematic, state-sponsored murder of entire groups determined by heredity. This applied to Jews, Gypsies, and the handicapped."[33]
While Jews began to flee abroad from the first days of the Nazi regime, only after Kristallnacht in November 1938 did Nazi policy switch categorically to the expulsion of all Jews from the Reich as its central aim. Although the Jews were ever-more intensively disemployed, defined as noncitizens, ostracized, stripped of wealth, brutalized, and encouraged to emigrate, they were not being killed by the government, and the majority of Germany’s five hundred thousand Jews managed to escape from the country before the outbreak of the war (though not necessarily to safety, as many wound up trapped in Poland and the Soviet Union). Indeed, so effective were the Nazis at expelling the Jews from their territories that about two-thirds of Austria’s two hundred thousand Jews managed to flee abroad in the short period between the German takeover of Austria in March 1938 and the closing of the borders to further Jewish emigration from the Reich in 1940-1941.

Death: Dr. Miklos Nyiszli was Mengele's prisoner pathologist. The autopsies became the final experiment. Nyiszli performed autopsies on twins who had died from the experiments or who had been purposely killed just for after-death measurements and examination. Some of the twins had been stabbed with a needle that pierced their heart and then was injected with chloroform or phenol, which caused near immediate blood coagulation and death. Some of the organs, eyes, blood samples and tissues would be sent to Verschuer for further study.
Over the next two years, Anne wrote faithfully in the diary, which she came to consider a friend, addressing many of the entries to “Dear Kitty.” In the journal and later notebooks, Anne recounted the day-to-day life within the annex. The close quarters and sparse supplies led to various arguments among the inhabitants, and the outgoing Anne came to find the conditions stifling. Heightening tensions was the ever-present concern that they would be discovered. However, many entries involve typical adolescent issues—jealousy toward her sister; annoyance with others, especially her mother; and an increasing sexual awareness. Anne wrote candidly about her developing body, and she experienced a brief romance with Peter van Pels. She also discussed her hopes for the future, which included becoming a journalist or a writer. In addition to the diary, Anne penned several short stories and compiled a list of “beautiful sentences” from other works.
In contemplating a dramatization and pledging no compromise, Levin told Frank he would do it “tenderly and with utmost fidelity.” He was clear about what he meant by fidelity. In his eyes the diary was conscious testimony to Jewish faith and suffering; and it was this, and this nearly alone, that defined for him its psychological, historical, and metaphysical genuineness, and its significance for the world. With these convictions foremost, Levin went in search of a theatrical producer. At the same time, he was unflagging in pressing for publication; but the work was meanwhile slowly gaining independent notice. Janet Flanner, in her “Letter from Paris” in The New Yorker of November 11, 1950, noted the French publication of a book by “a precocious, talented little Frankfurt Jewess”—apparently oblivious of the unpleasant echoes, post-Hitler, of “Jewess.” Sixteen English language publishers on both sides of the Atlantic had already rejected the diary when Levin succeeded in placing it with Valentine Mitchell, a London firm. His negotiations with a Boston house were still incomplete when Doubleday came forward to secure publication rights directly from Frank. Relations between Levin and Frank were, as usual, warm; Frank repeatedly thanked Levin for his efforts to further the fortunes of the diary, and Levin continued under the impression that Frank would support him as the playwright of choice.
Like the network of concentration camps that followed, becoming the killing grounds of the Holocaust, Dachau was under the control of Heinrich Himmler, head of the elite Nazi guard, the Schutzstaffel (SS), and later chief of the German police. By July 1933, German concentration camps (Konzentrationslager in German, or KZ) held some 27,000 people in “protective custody.” Huge Nazi rallies and symbolic acts such as the public burning of books by Jews, Communists, liberals and foreigners helped drive home the desired message of party strength.
After Germany’s loss in WWI, the Treaty of Versailles punished Germany by placing tough restrictions on the country. The treaty made Germany take full responsibility for the war, reduced the extent of German territory, severely limited the size and placement of their armed forces, and forced Germany to pay the allied powers reparations. These restrictions not only increased social unrest but, combined with the start of the Great Depression, collapsed the German economy as inflation rose alongside unemployment.

But they were gradually shut out of German society by the Nazis through a never-ending series of laws and decrees, culminating in the Nuremberg Laws of 1935 which deprived them of their German citizenship and forbade intermarriage with non-Jews. They were removed from schools, banned from the professions, excluded from military service, and were even forbidden to share a park bench with a non-Jew.

The impact of the Holocaust varied from region to region and from year to year in the 21 countries that were directly affected. Nowhere was the Holocaust more intense and sudden than in Hungary. What took place over several years in Germany occurred over 16 weeks in Hungary. Entering the war as a German ally, Hungary had persecuted its Jews but not permitted the deportation of Hungarian citizens. In 1941 foreign Jewish refugees were deported from Hungary and were shot by Germans in Kam’yanets-Podilskyy, Ukraine. After Germany invaded Hungary on March 19, 1944, the situation changed dramatically. By mid-April the Nazis had confined Jews to ghettos. On May 15, deportations began, and over the next 55 days the Nazis deported more than 437,000 Jews from Hungary to Auschwitz on 147 trains.

Mengele joined the Nazi Party in 1937 and the Schutzstaffel (SS; protection squadron) in 1938. He received basic training in 1938 with the Gebirgsjäger (light infantry mountain troop) and was called up for service in the Wehrmacht (Nazi armed forces) in June 1940, some months after the outbreak of World War II. He soon volunteered for medical service in the Waffen-SS, the combat arm of the SS, where he served with the rank of SS-Untersturmführer (second lieutenant) in a medical reserve battalion until November 1940. He was next assigned to the SS-Rasse- und Siedlungshauptamt (SS Race and Settlement Main Office) in Poznań, evaluating candidates for Germanization.[18][19]
