The invasion conquered a huge area, including the Baltic states, Belarus, and west Ukraine. After the successful Battle of Smolensk in September 1941, Hitler ordered Army Group Centre to halt its advance to Moscow and temporarily divert its Panzer groups to aid in the encirclement of Leningrad and Kiev.[117] This pause provided the Red Army with an opportunity to mobilise fresh reserves. The Moscow offensive, which resumed in October 1941, ended disastrously in December.[118] On 7 December 1941, Japan attacked Pearl Harbor, Hawaii. Four days later, Germany declared war on the United States.[119]
While no unified resistance movement opposing the Nazi regime existed, acts of defiance such as sabotage and labour slowdowns took place, as well as attempts to overthrow the regime or assassinate Hitler.[435] The banned Communist and Social Democratic parties set up resistance networks in the mid-1930s. These networks achieved little beyond fomenting unrest and initiating short-lived strikes.[436] Carl Friedrich Goerdeler, who initially supported Hitler, changed his mind in 1936 and was later a participant in the July 20 plot.[437][438] The Red Orchestra spy ring provided information to the Allies about Nazi war crimes, helped orchestrate escapes from Germany, and distributed leaflets. The group was detected by the Gestapo and more than 50 members were tried and executed in 1942.[439] Communist and Social Democratic resistance groups resumed activity in late 1942, but were unable to achieve much beyond distributing leaflets. The two groups saw themselves as potential rival parties in post-war Germany, and for the most part did not co-ordinate their activities.[440] The White Rose resistance group was primarily active in 1942–43, and many of its members were arrested or executed, with the final arrests taking place in 1944.[441] Another civilian resistance group, the Kreisau Circle, had some connections with the military conspirators, and many of its members were arrested after the failed 20 July plot.[442]

Today, the word Auschwitz has become synonymous with terror, genocide, and The Holocaust. The site, though partially destroyed by the retreating Nazi’s in 1945, has been established as a museum to help future generations understand the atrocities committed within its fences. By 2011, more than 30 million people had visited the camp, and during 2014 a record number of 1.5 million people visited the Auschwitz complex and museum. Spokespeople for the museum said that from January to April 2015, over 250,000 people visited Auschwitz, marking a 40% increase over the already large numbers from the previous year. Authorities in charge of the site began to urge people to book their visit to Auschwitz online ahead of time to prevent them from having to turn people away.

However, this regulation was soon waived and there is ample evidence that full Nazi Party members served in the Wehrmacht in particular after the outbreak of World War II. The Wehrmacht Reserves also saw a high number of senior Nazis enlisting, with Reinhard Heydrich and Fritz Todt joining the Luftwaffe, as well as Karl Hanke who served in the army.

The Reichskulturkammer (Reich Chamber of Culture) was organised under the control of the Propaganda Ministry in September 1933. Sub-chambers were set up to control aspects of cultural life such as film, radio, newspapers, fine arts, music, theatre and literature. Members of these professions were required to join their respective organisation. Jews and people considered politically unreliable were prevented from working in the arts, and many emigrated. Books and scripts had to be approved by the Propaganda Ministry prior to publication. Standards deteriorated as the regime sought to use cultural outlets exclusively as propaganda media.[455]
Notions of white supremacy and Aryan racial superiority were combined in the 19th century, with white supremacists maintaining the belief that certain groups of white people were members of an Aryan "master race" that is superior to other races and particularly superior to the Semitic race, which they associated with "cultural sterility".[80] Arthur de Gobineau, a French racial theorist and aristocrat, blamed the fall of the ancien régime in France on racial degeneracy caused by racial intermixing, which he argued had destroyed the purity of the Aryan race, a term which he only reserved for Germanic people.[81][82] Gobineau's theories, which attracted a strong following in Germany,[81] emphasized the existence of an irreconcilable polarity between Aryan (Germanic) and Jewish cultures.[80]

Things continued to get worse. The Germans began to require all Jewish people to wear yellow stars on their clothing. Some Jews were rounded up and taken to concentration camps. Then one day the order came that Margot would have to go to a labor camp. Otto was not going to let that happen. He and Edith had been preparing a place for the family to hide. The girls were told to pack up what they could. They had to wear all their clothes in layers because a suitcase would look too suspicious. Then they went to their hiding place.
Around 7,000 SS personnel were posted to Auschwitz during the war.[84] Of these, 4 percent of SS personnel were officers and 26 percent were non-commissioned officers, while the remainder were rank-and-file members.[85] Camp guards were members of the SS-Totenkopfverbände (Death's Head Units).[86] Approximately three in four SS personnel worked in security. Others worked in the medical or political departments, in the camp headquarters, or in the economic administration, which was responsible for the property of dead prisoners.[85] SS personnel at the camp included 200 women, who worked as guards, nurses, or messengers.[80] About 120 SS personnel were assigned to the gas chambers and lived on site at the crematoria.[87]

Lunch was three quarters of a liter of watery soup at midday, reportedly foul-tasting, with meat in the soup four times a week and vegetables (mostly potatoes and rutabaga) three times. The evening meal was 300 grams of bread, often moldy, part of which the inmates were expected to keep for breakfast the next day, with a tablespoon of cheese or marmalade, or 25 grams of margarine or sausage. Prisoners engaged in hard labor were given extra rations.[114]

The regime promoted the concept of Volksgemeinschaft, a national German ethnic community. The goal was to build a classless society based on racial purity and the perceived need to prepare for warfare, conquest and a struggle against Marxism.[451][452] The German Labour Front founded the Kraft durch Freude (KdF; Strength Through Joy) organisation in 1933. As well as taking control of tens of thousands of privately run recreational clubs, it offered highly regimented holidays and entertainment such as cruises, vacation destinations and concerts.[453][454]
Within the Nazi Party, the faction associated with anti-capitalist beliefs was the Sturmabteilung (SA), a paramilitary wing led by Ernst Röhm. The SA had a complicated relationship with the rest of the party, giving both Röhm himself and local SA leaders significant autonomy.[268] Different local leaders would even promote different political ideas in their units, including "nationalistic, socialistic, anti-Semitic, racist, völkisch, or conservative ideas."[269] There was tension between the SA and Hitler, especially from 1930 onward, as Hitler's "increasingly close association with big industrial interests and traditional rightist forces" caused many in the SA to distrust him.[270] The SA regarded Hitler's seizure of power in 1933 as a "first revolution" against the left, and some voices within the ranks began arguing for a "second revolution" against the right.[271] After engaging in violence against the left in 1933, Röhm's SA also began attacks against individuals deemed to be associated with conservative reaction.[45] Hitler saw Röhm's independent actions as violating and possibly threatening his leadership, as well as jeopardising the regime by alienating the conservative President Paul von Hindenburg and the conservative-oriented German Army.[46] This resulted in Hitler purging Röhm and other radical members of the SA in 1934, during the Night of the Long Knives.[46]
Use of the word "concentration" came from the idea of confining people in one place because they belong to a group that is considered undesirable in some way. The term itself originated in 1897 when the "reconcentration camps" were set up in Cuba by General Valeriano Weyler. In the past, the U.S. government had used concentration camps against Native Americans and the British had also used them during the Second Boer War. Between 1904 and 1908, the Schutztruppe of the Imperial German Army operated concentration camps in German South-West Africa (now Namibia) as part of its genocide of the Herero and Namaqua peoples. The Shark Island Concentration Camp in Lüderitz was the largest camp and the one with the harshest conditions.
