Holocaust, Hebrew Shoʾah (“Catastrophe”), Yiddish and Hebrew Ḥurban (“Destruction”), the systematic state-sponsored killing of six million Jewish men, women, and children and millions of others by Nazi Germany and its collaborators during World War II. The Germans called this “the final solution to the Jewish question.” Yiddish-speaking Jews and survivors in the years immediately following their liberation called the murder of the Jews the Ḥurban, the word used to describe the destruction of the First Temple in Jerusalem by the Babylonians in 586 bce and the destruction of the Second Temple by the Romans in 70 ce. Shoʾah (“Catastrophe”) is the term preferred by Israelis and the French, most especially after Claude Lanzmann’s masterful 1985 motion picture documentary of that title. It is also preferred by people who speak Hebrew and by those who want to be more particular about the Jewish experience or who are uncomfortable with the religious connotations of the word Holocaust. Less universal and more particular, Shoʾah emphasizes the annihilation of the Jews, not the totality of Nazi victims. More particular terms also were used by Raul Hilberg, who called his pioneering work The Destruction of the European Jews, and Lucy S. Dawidowicz, who entitled her book on the Holocaust The War Against the Jews. In part she showed how Germany fought two wars simultaneously: World War II and the racial war against the Jews. The Allies fought only the World War. The word Holocaust is derived from the Greek holokauston, a translation of the Hebrew word ʿolah, meaning a burnt sacrifice offered whole to God. This word was chosen because in the ultimate manifestation of the Nazi killing program—the extermination camps—the bodies of the victims were consumed whole in crematoria and open fires.

From 1933 onward, anti-Jewish propaganda had flooded Germany. Under the skillful direction of Joseph Goebbels, his Nazi Propaganda Ministry churned out a ceaseless stream of leaflets, posters, newspaper articles, cartoons, newsreels, slides, movies, speeches, records, exhibits and radio pronouncements. As a result, the accusations, denunciations and opinions which Hitler first expressed in his book, Mein Kampf, had become institutionalized, accepted as time-tested beliefs by all Nazis, taught as fact to impressionable youths, and drilled into the minds of eager-to-please SS recruits.

The Nazis set about killing people with physical and mental disabilities, whom they regarded as a burden on the state and a threat to the nation's 'racial hygiene'. About 170,000 people were eventually killed under this so-called Euthanasia programme, which also pioneered techniques and employed many of the people later used to kill Jews.
There are two versions of the diary written by Anne Frank. She wrote the first version in a designated diary and two notebooks (version A), but rewrote it (version B) in 1944 after hearing on the radio that war-time diaries were to be collected to document the war period. Version B was written on loose paper, and is not identical to Version A, as parts were added and others omitted.[22]

Mengele is known as the “Angel of Death,” or sometimes as the “White Angel,” for his coldly cruel demeanor on the ramp. He is associated more closely with this “selection duty” than any other medical officer at Auschwitz, although by most accounts he performed this task no more often than any of his colleagues. The association is partially explained by his postwar notoriety. The pervasive image of Mengele at the ramp in so many survivors' accounts has also to do with the fact that Mengele often appeared “off-duty” in the selection area whenever trainloads of new prisoners arrived at Auschwitz, searching for twins.
It is the shamelessness of appropriation. Who owns Anne Frank? The children of the world, say the sentimentalists. A case in point is the astonishing correspondence, published in 1995 under the title “Love, Otto,” between Cara Wilson, a Californian born in 1944, and Otto Frank, the father of Anne Frank. Wilson, then twelve-year-old Cara Weiss, was invited by Twentieth Century Fox to audition for the part of Anne in a projected film version of the diary. “I didn’t get the part,” the middle-aged Wilson writes, “but by now I had found a whole new world. Anne Frank’s diary, which I read and reread, spoke to me and my dilemmas, my anxieties, my secret passions. She felt the way I did. . . .I identified so strongly with this eloquent girl of my own age, that I now think I sort of became her in my own mind.” And on what similarities does Wilson rest her acute sense of identification with a hunted child in hiding?
Nevertheless, some acts of rescue seem to have been unplanned, spontaneous extensions of a general habit to help the needy. Indeed, most rescuers do not appear to have thought carefully about their actions or analyzed them; instead, they viewed their assistance to Jews as a natural reaction to human suffering. Some even insisted in postwar interviews that there was nothing special about what they did to save Jewish lives. Only a small fraction of rescuers saw their saving of Jews as extraordinary. A large majority of rescuers described aiding Jews because they were in pain and in need, while just over one-quarter said that they helped because it was a Christian duty. About half saw their actions as a protest against the occupation. For some rescuers, such attitudes required protecting even people they disliked.
Whereas Christopher Browning places the Nazi plan to exterminate the Jews in the context of the Wehrmacht victories on the Eastern front, Cesarani argues that the German subsequent realisation that there would be no swift victory over the Soviet Union "scuppered the last territorial 'solution' still on the table: expulsion to Siberia".[119] Germany's declaration of war on the United States on December 11, 1941, "meant that holding European Jews hostage to deter the US from entering the conflict was now pointless. As Joseph Goebbels put it when he summarised a secret speech Hitler made on 12 December 1941: 'The world war is here, the destruction of the Jews must be the inevitable consequence'."[119][120] Cesarani concludes, the Holocaust "was rooted in anti-Semitism, but it was shaped by war".[119] The fact that the Nazis were, ultimately, so successful in killing between five and six million Jews was not due to the efficiency of the Third Reich or the clarity of their policies. "Rather, the catastrophic rate of killing was due to German persistence … and the duration of the murderous campaigns. This last factor was largely a consequence of allied military failure."[121]
What happened next—an avalanche of furies and recriminations lasting years—has lately become the subject of a pair of arresting discussions of the Frank-Levin affair. And if “affair” suggests an event on the scale of the Dreyfus case, that is how Levin saw it: as an unjust stripping away of his rightful position, with implications far beyond his personal predicament. “An Obsession with Anne Frank,” by Lawrence Graver, published by the University of California Press in 1995, is the first study to fashion a coherent narrative out of the welter of claims, counterclaims, letters, cables, petitions, polemics, and rumbling confusions which accompany any examination of the diary’s journey to the stage. “The Stolen Legacy of Anne Frank,” by Ralph Melnick, out just now from Yale, is denser in detail and in sources than its predecessor, and more insistent in tone. Both are accomplished works of scholarship that converge on the facts and diverge in their conclusions. Graver is reticent with his sympathies; Melnick is Levin’s undisguised advocate. Graver finds no villains; Melnick finds Lillian Hellman.

Similarly, in Ordinary Men (1992), Christopher Browning examined the deeds of German Reserve Police Battalion 101 of the Ordnungspolizei ("order police"), used to commit massacres and round-ups of Jews, as well as mass deportations to the death camps. The members of the battalion were middle-aged men of working-class background from Hamburg, who were too old for regular military duty. They were given no special training. During the murder of 1,500 Jews from Józefów in Poland, their commander allowed them to opt out of direct participation. Fewer than 12 men out of a battalion of 500 did so. Influenced by the Milgram experiment on obedience, Browning argued that the men killed out of peer pressure, not bloodlust.[471]
The fire signaled the demise of German democracy. On the next day, the government, under the pretense of controlling the Communists, abolished individual rights and protections: freedom of the press, assembly, and expression were nullified, as well as the right to privacy. When the elections were held on March 5, the Nazis received nearly 44 percent of the vote, and with 8 percent offered by the Conservatives, won a majority in the government.
The Final Solution was a plan of Adolf Hitler's to kill all the Jews in Europe. Hitler's Anti- Semitic ideas were so strong that he released hatred by mass murder. Before Hitler decided to become dictator the Final Solution was already in his head. In a couple of books written by Gerald Fleming Hitler says '' Once I  am really in power my first task will be the genocide of the Jews .'' He achieved his goal by killing six million Jews. Hitler began  the final solution in every European Nation he was  control of. The Jews were sent to concentration/death camps.

You find gripping and horrifying stories of Adolf Hitler and his most ruthless henchmen - men often seen as the very personifications of evil, like Rudolf Hoess, the SS Commandant of Auschwitz, the Nazi butcher Amon Goeth at Plaszow and Josef Mengele, The Angel Of Death. You may read about Hitler's wife, Eva Braun, or Admiral Wilhelm Canaris, Chief of the German Military Intelligence who was a dedicated anti-Nazi and held Hitler in utter contempt. He tried to put a stop to the crimes of war and genocide committed by the Nazis.

Here over an acre of ground lay dead and dying people. You could not see which was which. ... The living lay with their heads against the corpses and around them moved the awful, ghostly procession of emaciated, aimless people, with nothing to do and with no hope of life, unable to move out of your way, unable to look at the terrible sights around them ... Babies had been born here, tiny wizened things that could not live. ... A mother, driven mad, screamed at a British sentry to give her milk for her child, and thrust the tiny mite into his arms. ... He opened the bundle and found the baby had been dead for days. This day at Belsen was the most horrible of my life.
Here the prophet Isaiah is offering reassurance to two classes of people. The first is the nekhar, or alien, a word that in this context clearly refers to a Gentile (as it does elsewhere in the Bible). While such a person—the reference may be to a convert or to one taking on the intermediate status of a God-fearing non-Jew—might fear that not being born a Jew places an insurmountable barrier between him and God, the prophet assures him to the contrary.
Twins were subjected to weekly examinations and measurements of their physical attributes by Mengele or one of his assistants.[49] The experiments he performed on twins included unnecessary amputation of limbs, intentionally infecting one twin with typhus or some other disease, and transfusing the blood of one twin into the other. Many of the victims died while undergoing these procedures,[50] and those who survived the experiments were sometimes killed and their bodies dissected once Mengele had no further use for them.[51] Nyiszli recalled one occasion on which Mengele personally killed fourteen twins in one night by injecting their hearts with chloroform.[31] If one twin died from disease, he would kill the other twin to allow comparative post-mortem reports to be produced for research purposes.[52]
