Italy introduced some antisemitic measures, but there was less antisemitism there than in Germany, and Italian-occupied countries were generally safer for Jews than German-occupied territories. In some areas, the Italian authorities even tried to protect Jews, such as in the Croatian areas of the Balkans. But while Italian forces in Russia were not as vicious towards Jews as the Germans, they did not try to stop German atrocities either. There were no deportations of Italian Jews to Germany while Italy remained an ally. Several forced labor camps for Jews were established in Italian-controlled Libya. Almost 2,600 Libyan Jews were sent to camps, where 562 died.
Political dissidents, trade unionists, and Social Democrats were among the first to be arrested and incarcerated in concentration camps. Under the Weimar government, centuries-old prohibitions against homosexuality had been overlooked, but this tolerance ended violently when the SA (Storm Troopers) began raiding gay bars in 1933. Homosexual intent became just cause for prosecution. The Nazis arrested German and Austrian male homosexuals—there was no systematic persecution of lesbians—and interned them in concentration camps, where they were forced to wear special yellow armbands and later pink triangles. The goal of persecuting male homosexuals was either for reeducation—what might now be called conversion therapy—or punishment. Jehovah’s Witnesses were a problem for the Nazis because they refused to swear allegiance to the state, register for the draft, or utter the words “Heil Hitler.” As a result, the Nazis imprisoned many of the roughly 20,000 Jehovah’s Witnesses in Germany. They could be released from concentration camps if they signed a document renouncing their faith and promising not to proselytize. Few availed themselves of that option, preferring martyrdom to apostasy. Germans of African descent—many of whom, called “Rhineland bastards” by the Nazis, were the offspring of German mothers and French colonial African troops who had occupied the Rhineland after World War I—were also persecuted by the Nazis. Although their victimization was less systematic, it included forced sterilization and, often, internment in concentration camps. The fear was that they would “further pollute” and thereby diminish the race. The Nazis also singled out the Roma and Sinti, pejoratively known as Gypsies. They were the only other group that the Nazis systematically killed in gas chambers alongside the Jews. For the Roma and Sinti, too, racial pollution and their depiction as asocials was the justification for their persecution and murder.
"Blitzkrieg" is a German compound meaning "lightning war". The word did not enter official terminology of the Wehrmacht either before or during the war, even though it was already used in the military Journal "Deutsche Wehr" in 1935, in the context of an article on how states with insufficient food and raw materials supply can win a war. Another appearance is in 1938 in the "Militär-Wochenblatt", where Blitzkrieg is defined as a "strategic attack", carried out by operational use of tanks, air force, and airborne troops. Karl-Heinz Frieser in his book 'Blitzkrieg Legende', who researched the origin of the term and found the above examples, points out that the pre-war use of the term is rare, and that it practically never entered official terminology throughout the war.
Those deemed fit enough for slave labor were then immediately registered, tattooed with a serial number, undressed, deloused, had their body hair shaven off, showered while their clothes were disinfected with Zyklon-B gas, and entered the camp under the infamous gateway inscribed “Arbeit Macht Frei” (“Labor will set you free”). Of approximately 2.5 million people who were deported to Auschwitz, 405,000 were given prisoner status and serial numbers. Of these, approximately 50% were Jews and 50% were Poles and other nationalities.
The understanding of operations in Poland has shifted considerably since the Second World War. Many early postwar histories incorrectly attribute German victory to "enormous development in military technique which occurred between 1918 and 1940", incorrectly citing that "Germany, who translated (British inter-war) theories into action...called the result Blitzkrieg." More recent histories identify German operations in Poland as relatively cautious and traditional. Matthew Cooper wrote that
The group raced to the English Channel, reaching the coast at Abbeville and cut off the BEF, the Belgian Army and some of the best-equipped divisions of the French Army in northern France. Armoured and motorised units under Guderian, Rommel and others, advanced far beyond the marching and horse-drawn infantry divisions and far in excess of that with which Hitler and the German high command expected or wished. When the Allies counter-attacked at Arras using the heavily armoured British Matilda I and Matilda II tanks, a brief panic was created in the German High Command. The armoured and motorised forces were halted by Hitler outside the port of Dunkirk, which was being used to evacuate the Allied forces. Hermann Göring promised that the Luftwaffe would complete the destruction of the encircled armies but aerial operations failed to prevent the evacuation of the majority of the Allied troops. In Operation Dynamo some 330,000 French and British troops escaped.
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.
This aggressive technique is best used nowadays by visionary companies that accept the task to reshape certain industries. Being first confers the advantages of superior size that comes with being ahead of rivals and allows the business to set industry standards, influence customer preferences, develop a superior cost position, and determine the direction for an entire market.
Policies differed widely among Germany’s Balkan allies. In Romania it was primarily the Romanians themselves who slaughtered the country’s Jews. Toward the end of the war, however, when the defeat of Germany was all but certain, the Romanian government found more value in living Jews who could be held for ransom or used as leverage with the West. Bulgaria deported Jews from neighbouring Thrace and Macedonia, which it occupied, but government leaders faced stiff opposition to the deportation of native Bulgarian Jews, who were regarded as fellow citizens.
In the German parliament, the Nazi party, led by Adolf Hitler, gained popularity. The number of seats Nazis controlled in the parliament rose from 12 in 1928 to 230 in 1932, making them the largest political party. The strong showing guaranteed the Nazi party would need to be part of any political coalition. Believing he could check Hitler’s ambition, President Hindenburg reluctantly made Hitler the Chancellor of Germany on January 30, 1933.
Nazi racial policy aimed at forcing Jews to emigrate. Fifty thousand German Jews had left Germany by the end of 1934, and by the end of 1938, approximately half the German Jewish population had left the country. Among the prominent Jews who left was the conductor Bruno Walter, who fled after being told that the hall of the Berlin Philharmonic would be burned down if he conducted a concert there. Albert Einstein, who was in the United States when Hitler came to power, never returned to Germany; he was expelled from the Kaiser Wilhelm Society and the Prussian Academy of Sciences and his citizenship was revoked. Other Jewish scientists, including Gustav Hertz, lost their teaching positions and left the country. On 12 March 1938, Germany annexed Austria. Austrian Nazis broke into Jewish shops, stole from Jewish homes and businesses, and forced Jews to perform humiliating acts such as scrubbing the streets or cleaning toilets. Jewish businesses were "Aryanized", and all the legal restrictions on Jews in Germany were imposed. In August that year, Adolf Eichmann was put in charge of the Central Agency for Jewish Emigration in Vienna (Zentralstelle für jüdische Auswanderung in Wien). About 100,000 Austrian Jews had left the country by May 1939, including Sigmund Freud and his family, who moved to London. The Évian Conference was held in July 1938 by 32 countries as an attempt to help the increased refugees from Germany, but aside from establishing the largely ineffectual Intergovernmental Committee on Refugees, little was accomplished and most countries participating did not increase the number of refugees they would accept.
Schindler grew up in Svitavy, Moravia, and worked in several trades until he joined the Abwehr, the military intelligence service of Nazi Germany, in 1936. He joined the Nazi Party in 1939. Prior to the German occupation of Czechoslovakia in 1938, he collected information on railways and troop movements for the German government. He was arrested for espionage by the Czechoslovak government but was released under the terms of the Munich Agreement in 1938. Schindler continued to collect information for the Nazis, working in Poland in 1939 before the invasion of Poland at the start of World War II. In 1939, Schindler acquired an enamelware factory in Kraków, Poland, which employed at the factory's peak in 1944 about 1,750 workers, of whom 1,000 were Jews. His Abwehr connections helped Schindler protect his Jewish workers from deportation and death in the Nazi concentration camps. As time went on, Schindler had to give Nazi officials ever larger bribes and gifts of luxury items obtainable only on the black market to keep his workers safe.
