The fortified walls, barbed wire, platforms, barracks, gallows, gas chambers and cremation ovens show the conditions within which the Nazi genocide took place in the former concentration and extermination camp of Auschwitz-Birkenau, the largest in the Third Reich. According to historical investigations, 1.5 million people, among them a great number of Jews, were systematically starved, tortured and murdered in this camp, the symbol of humanity's cruelty to its fellow human beings in the 20th century.
In October 1939 Hitler signed a "euthanasia decree" backdated to 1 September 1939 that authorized Reichsleiter Philipp Bouhler, the chief of Hitler's Chancellery, and Karl Brandt, Hitler's personal physician, to carry out a program of involuntary "euthanasia"; after the war this program was named Aktion T4.[98] It was named after Tiergartenstraße 4, the address of a villa in the Berlin borough of Tiergarten, where the various organizations involved were headquartered.[99] T4 was mainly directed at adults, but the "euthanasia" of children was also carried out.[100] Between 1939 and 1941, 80,000 to 100,000 mentally ill adults in institutions were killed, as were 5,000 children and 1,000 Jews, also in institutions. In addition there were specialized killing centres, where the deaths were estimated at 20,000, according to Georg Renno, the deputy director of Schloss Hartheim, one of the "euthanasia" centers, or 400,000, according to Frank Zeireis, the commandant of the Mauthausen concentration camp.[101] Overall, the number of mentally and physically handicapped murdered was about 150,000.[102]
In the Sinai and Palestine Campaign, operations involved some aspects of what would later be called blitzkrieg.[38] Key elements in the "blitzkrieg warfare" at the decisive Battle of Megiddo included concentration, surprise and speed; success depended on attacking only in terrain favoring the movement of large formations around the battlefield and tactical improvements in the British artillery and infantry attack.[39][40] General Edmund Allenby used infantry to attack the strong Ottoman front line in co-operation with supporting artillery, augmented by the guns of two destroyers.[41][42] Through constant pressure by infantry and cavalry, two Ottoman armies in the Judean Hills were kept off-balance and virtually encircled during the Battles of Sharon and Nablus (Battle of Megiddo).[43]
“I use ‘disruptive’ in both its good and bad connotations. Disruptive scientific and technological progress is not to me inherently good or inherently evil. But its arc is for us to shape. Technology’s progress is furthermore in my judgment unstoppable. But it is quite incorrect that it unfolds inexorably according to its own internal logic and the laws of nature.”
Voldemort coming back was always a lingering danger in the early Harry Potter books and movies, as fans waited eagerly to see the Dark Lord reborn and return to full power. It was definitely worth the wait when we were finally able to watch Voldemort return toward the end of Harry Potter and the Goblet of Fire, the fourth book—and movie—in the series.
The United States Holocaust Memorial Museum defines the Holocaust as the "systematic, bureaucratic, state-sponsored persecution and murder of six million Jews by the Nazi regime and its collaborators",[29] distinguishing between the Holocaust and the targeting of other groups during "the era of the Holocaust".[30] According to Yad Vashem, Israel's Holocaust memorial, most historians regard the start of the "Holocaust era" as January 1933, when Hitler was named Chancellor of Germany.[31] Other victims of the Holocaust era include those viewed as inferior, including for reasons of race or ethnicity (such as the Roma, ethnic Poles, Russians, and the disabled); and those targeted because of their beliefs or behavior (such as Jehovah's Witnesses, communists, and homosexuals).[30] Hitler came to see the Jews as "uniquely dangerous to Germany", according to Peter Hayes, "and therefore uniquely destined to disappear completely from the Reich and all territories subordinate to it". The persecution and murder of other groups was much less consistent. For example, he writes, the Nazis regarded the Slavs as "sub-human", but their treatment consisted of "enslavement and gradual attrition", while "some Slavs—Slovaks, Croats, Bulgarians, some Ukrainians—[were] allotted a favored place in Hitler's New Order".[20]
Once a strategic target had been selected, Stuka dive bombers were sent in to ‘soften’ up the enemy, destroy all rail lines, communication centres and major rail links. This was done as the German tanks were approaching and the planes withdrew only at the last minute so that the enemy did not have time to recover their senses when the tanks attacked supported by infantry. 
Although effective in quick campaigns against Poland and France, blitzkrieg could not be sustained by Germany in later years. Blitzkrieg strategy has the inherent danger of the attacking force overextending its supply lines, and the strategy as a whole can be defeated by a determined foe who is willing to sacrifice territory for time in which to regroup and rearm, as the Soviets did on the Eastern Front. Tank and vehicle production was a constant problem for Germany; indeed, late in the war many panzer "divisions" had no more than a few dozen tanks. As the end of the war approached, Germany also experienced critical shortages in fuel and ammunition stocks as a result of Anglo-American strategic bombing. Although production of Luftwaffe fighter aircraft continued, they would be unable to fly for lack of fuel. What fuel there was went to panzer divisions, and even then they were not able to operate normally. Of those Tiger tanks lost against the United States Army, nearly half of them were abandoned for lack of fuel.

To visit Auschwitz- Birkenau is a must. Everything is so good preserve and it learns you about the horris that hapeend to the poor people , woman and the small children. The blocks that shows you the glasses , hair and suitcases let you image how the people arrived there unknown what hell they are going to meet. Please visit these camps and tell all your friends to visit. we must learn so it will never happend again. I am takeing my brother and his family the November 2009. Been there 3 times already with different people. Since I visit auschwitz-Birkenau, Mathausen 9Austria)and Dachau (Germany), I cry each day thinking about the poor innocent people.
In the fall of that year the Płaszów work camp opened nearby, and by February 1943 it was under the command of the notoriously sadistic SS officer Amon Göth, who would be executed after the war. Capitalizing on the officer’s appetite for drink and other luxury items available mainly on the black market, Schindler cultivated his friendship by ensuring a constant stream of them to the villa from which he oversaw the camp. Schindler thus managed to prevail upon Göth to create a separate camp for his Jewish workers, where they were free of the abuses suffered at Płaszów. Though Schindler’s motivations prior to this point are unclear, many scholars interpret his efforts to extricate his workers from Płaszów as indication that his concern for them was not purely financial.

Prior to the German offensive in May, Winston Churchill had said "Thank God for the French Army".[89] That same French army collapsed after barely two months of fighting. This was in shocking contrast to the four years of trench warfare they had engaged in during the First World War. The French president of the Ministerial Council, Reynaud, attributed the collapse in a speech on 21 May 1940:
Hitler quickly moved to cement his power by suspending many civil liberties and allowing imprisonment without trial. By March, the first Nazi concentration camp was established at Dachau, not to imprison Jews but to hold political dissidents. Further laws targeted Jews, restricting the jobs they could hold and revoking their German citizenship. Anti-Semitic sentiment increased as the Jewish population was blamed for many of Germany's recent and historical problems.
As Soviet armies advanced in 1944 and early 1945, Auschwitz was gradually abandoned. On January 18, 1945, some 60,000 prisoners were marched to Wodzisław Śląski, where they were put on freight trains (many in open cars) and sent westward to concentration camps away from the front. One in four died en route from starvation, cold, exhaustion, and despair. Many were shot along the way in what became known as the “death marches.” The 7,650 sick or starving prisoners who remained were found by arriving Soviet troops on January 27, 1945.
Some ghettos were initially open, which meant that Jews could leave the area during the daytime but had to be back by a curfew. Later, all ghettos became closed, meaning that Jews were not allowed to leave under any circumstances. Major ghettos were located in the cities of Polish cities of Bialystok, Lodz, and Warsaw. Other ghettos were found in present-day Minsk, Belarus; Riga, Latvia; and Vilna, Lithuania. The largest ghetto was in Warsaw. At its peak in March 1941, some 445,000 were crammed into an area just 1.3 square miles in size.

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 German view of the Roma as hereditary criminals and "asocials" was reflected in their classification in the concentration camps, where they were usually counted among the asocials and given black triangles to wear.[420] According to Niewyk and Nicosia, at least 130,000 died out of nearly one million in German-occupied Europe.[415] The United States Holocaust Memorial Museum calculates at least 220,000.[421] Ian Hancock, who specializes in Romani history and culture, argues for between 500,000 and 1,500,000.[422] The treatment of the Roma was not consistent across German-occupied territories. Those in France and the Low Countries were subject to restrictions on movement and some confinement to collection camps, while those in Central and Eastern Europe were sent to concentration camps and murdered by soldiers and execution squads.[423] Before being sent to the camps, the Roma were herded into ghettos, including several hundred into the Warsaw Ghetto.[219] Further east, teams of Einsatzgruppen tracked down Romani encampments and murdered the inhabitants on the spot, leaving no records of the victims.[423] After the Germans occupied Hungary, 1,000 Roma were deported to Auschwitz.[424][x]
Moreover, one of the key successes of the Blitzkrieg was its use of FM radios – these enabled the forces that had broken through the lines to inform support units as to their progress and relay information on what was behind enemy lines. This superior intelligence was a crucial tool at the German’s disposal and allowed them to perform far more organised assaults on the enemy. The communication technology promoted quick, decentralised decision-making that was key to this speed focused approach.
German doctors performed a variety of experiments on prisoners at Auschwitz. SS doctors tested the efficacy of X-rays as a sterilization device by administering large doses to female prisoners. Carl Clauberg injected chemicals into women's uteruses in an effort to glue them shut. Prisoners were infected with spotted fever for vaccination research and exposed to toxic substances to study the effects.[125] In one experiment Bayer, then part of IG Farben, paid RM 150 each for 150 female inmates from Auschwitz (the camp had asked for RM 200 per woman), who were transferred to a Bayer facility to test an anesthetic. A Bayer employee wrote to Rudolf Höss: "The transport of 150 women arrived in good condition. However, we were unable to obtain conclusive results because they died during the experiments. We would kindly request that you send us another group of women to the same number and at the same price." The Bayer research was led at Auschwitz by Helmuth Vetter of Bayer/IG Farben, who was also an Auschwitz physician and SS captain, and by Auschwitz physicians Friedrich Entress and Eduard Wirths.[126]
^ Some of the military historians who consider Operation Citadel, or at least the southern pincer, as envisioning a blitzkrieg attack or state it was intended as such are: Lloyd Clark (Clark 2012, p. 187), Roger Moorhouse (Moorhouse 2011, p. 342), Mary Kathryn Barbier (Barbier 2002, p. 10), David Glantz (; Glantz & House 2004, pp. 63, 78, 149, 269, 272, 280), Jonathan House (Glantz & House 2004, pp. 63, 78, 149, 269, 272, 280), Hedley Paul Willmott (Willmott 1990, p. 300), Oscar Pinkus (Pinkus 2005, p. 35) and others.
The Blitzkrieg was fundamentally about moving away from the tried and tested methods of modern warfare and creating a new, more effective doctrine. To that end, Hitler had given his full backing to Guderian. Ironically, he had got his idea for Blitzkrieg from two officers – one from France and one from Britain and he had copied and broadened what they had put on paper. In Britain and France, however, the cavalry regiments ruled supreme and they were adamant that the tanks would not get any influence in their armies. The High Commands of both countries were dominated by the old traditional cavalry regiments and their political pull was great. These were the type of officers despised by Hitler and he took to his Panzer officer, Guderian, over the old officers that were in the German Army (the Wehrmacht). 
Another scene in the movie that Crowe believes never happened is the depiction of Oskar Schindler on horseback watching from a hill in 1943 as a young Jewish girl in a red coat seeks a hiding place during the ruthless closing of the Krakow ghetto. Crowe writes that Spielberg included the scene to show an epiphany, a moment that motivated Schindler into action. But it is unlikely during the middle of such a major action Oskar Schindler and his girlfriend would be taking a pleasure ride on horseback. “There is nothing to indicate that Oskar and his mistress were ever on Lasota Hill on March 13th and 14th. He was well aware of the coming Aktion and was more concerned about the fate of his Jewish workers,” notes Crowe.

The wounds of the Holocaust–known in Hebrew as Shoah, or catastrophe–were slow to heal. Survivors of the camps found it nearly impossible to return home, as in many cases they had lost their families and been denounced by their non-Jewish neighbors. As a result, the late 1940s saw an unprecedented number of refugees, POWs and other displaced populations moving across Europe.

Historians increasingly view the Holocaust as a pan-European phenomenon, or a series of holocausts impossible to conduct without the help of local collaborators.[47] Over 200,000 people are estimated to have been Holocaust perpetrators;[48] without them, the Germans would not have been able to extend the Holocaust across most of Europe.[49] Some Christian churches tried to defend the Jews by declaring that converted Jews were "part of the flock," according to Saul Friedländer, "but even then only up to a point". Otherwise, Friedländer writes, "[n]ot one social group, not one religious community, not one scholarly institution or professional association in Germany and throughout Europe declared its solidarity with the Jews."[50]
The Theresienstadt family camp, which existed between September 1943 and July 1944, served a different purpose. A group of around 5,000 Jews had arrived in Auschwitz in September 1943 from the Theresienstadt ghetto in Czechoslovakia. The families were allowed to stay together, their heads were not shaved, and they could wear their own clothes. Correspondence between Adolf Eichmann's office and the International Red Cross suggests that the Germans set up the camp to cast doubt on reports, in time for a planned Red Cross visit to Auschwitz, that mass murder was taking place in Auschwitz. A second group of 5,000 arrived from Theresienstadt in December 1943. On 7 March 1944, the first group was sent to the gas chamber at crematorium III; before they died, they were asked to send postcards to relatives, postdated to 25 March.[148] This was the largest massacre of Czechoslovak citizens in history. News of the liquidation reached the Czechoslovak government-in-exile, which initiated diplomatic manoeuvers to save the remaining Jews. After the Red Cross visited Theresienstadt in June 1944 and were persuaded by the SS that no deportations were taking place from there, about 3,500 Jews were removed from the family camp to other sections of Auschwitz. The remaining 6,500 were murdered in the gas chambers between 10 and 12 July 1944.[149][150]
With the financial backing of several Jewish investors, including one of the owners, Abraham Bankier, Schindler signed an informal lease agreement on the factory on 13 November 1939 and formalised the arrangement on 15 January 1940.[b] He renamed it Deutsche Emailwarenfabrik (German Enamelware Factory) or DEF, and it soon became known by the nickname "Emalia".[25][26] He initially acquired a staff of seven Jewish workers (including Abraham Bankier, who helped him manage the company[27]) and 250 non-Jewish Poles.[28] At its peak in 1944, the business employed around 1,750 workers, a thousand of whom were Jews.[29] Schindler also helped run Schlomo Wiener Ltd, a wholesale outfit that sold his enamelware, and was leaseholder of Prokosziner Glashütte, a glass factory.[30]
