While top officials reported to Hitler and followed his policies, they had considerable autonomy.[194] He expected officials to "work towards the Führer" – to take the initiative in promoting policies and actions in line with party goals and Hitler's wishes, without his involvement in day-to-day decision-making.[195] The government was a disorganised collection of factions led by the party elite, who struggled to amass power and gain the Führer's favour.[196] Hitler's leadership style was to give contradictory orders to his subordinates and to place them in positions where their duties and responsibilities overlapped.[197] In this way he fostered distrust, competition, and infighting among his subordinates to consolidate and maximise his own power.[198]
In its racial categorization, Nazism viewed what it called the Aryan race as the master race of the world—a race that was superior to all other races.[136] It viewed Aryans as being in racial conflict with a mixed race people, the Jews, whom the Nazis identified as a dangerous enemy of the Aryans. It also viewed a number of other peoples as dangerous to the well-being of the Aryan race. In order to preserve the perceived racial purity of the Aryan race, a set of race laws was introduced in 1935 which came to be known as the Nuremberg Laws. At first these laws only prevented sexual relations and marriages between Germans and Jews, but they were later extended to the "Gypsies, Negroes, and their bastard offspring", who were described by the Nazis as people of "alien blood".[137][138] Such relations between Aryans (cf. Aryan certificate) and non-Aryans were now punishable under the race laws as Rassenschande or "race defilement".[137] After the war began, the race defilement law was extended to include all foreigners (non-Germans).[139] At the bottom of the racial scale of non-Aryans were Jews, Romanis, Slavs[140] and blacks.[141] To maintain the "purity and strength" of the Aryan race, the Nazis eventually sought to exterminate Jews, Romani, Slavs and the physically and mentally disabled.[140][142] Other groups deemed "degenerate" and "asocial" who were not targeted for extermination, but were subjected to exclusionary treatment by the Nazi state, included homosexuals, blacks, Jehovah's Witnesses and political opponents.[142] One of Hitler's ambitions at the start of the war was to exterminate, expel or enslave most or all Slavs from Central and Eastern Europe in order to acquire living space for German settlers.[143]

While unmarried until the very end of the regime, Hitler often made excuses about his busy life hindering any chance for marriage.[188] Among National Socialist ideologues, marriage was valued not for moral considerations but because it provided an optimal breeding environment. Reichsführer-SS Heinrich Himmler reportedly told a confidant that when he established the Lebensborn program, an organisation that would dramatically increase the birth rate of "Aryan" children through extramarital relations between women classified as racially pure and their male equals, he had only the purest male "conception assistants" in mind.[189]
Auschwitz was considered a comfortable posting by many SS members, because of its many amenities.[84] SS personnel were initially allowed to bring partners, spouses, and children to live at the camp, but when the SS camp grew more crowded, Höss restricted further arrivals. Facilities for the SS personnel and their families included a library, swimming pool, coffee house, and a theater that hosted regular performances.[80]
For Hitler, the twin goals of the party were always German nationalist expansionism and antisemitism. These two goals were fused in his mind by his belief that Germany's external enemies – Britain, France and the Soviet Union – were controlled by the Jews and that Germany's future wars of national expansion would necessarily entail a war against the Jews.[64] For Hitler and his principal lieutenants, national and racial issues were always dominant. This was symbolised by the adoption as the party emblem of the swastika or Hakenkreuz. In German nationalist circles, the swastika was considered a symbol of an "Aryan race" and it symbolised the replacement of the Christian Cross with allegiance to a National Socialist State.
The first camp in Germany, Dachau, was founded in March 1933.[13] The press announcement said that "the first concentration camp is to be opened in Dachau with an accommodation for 5,000 people. All Communists and – where necessary – Reichsbanner and Social Democratic functionaries who endanger state security are to be concentrated there, as in the long run it is not possible to keep individual functionaries in the state prisons without overburdening these prisons."[13] Dachau was the first regular concentration camp established by the German coalition government of National Socialist Workers' Party (Nazi Party) and the Nationalist People's Party (dissolved on 6 July 1933). Heinrich Himmler, then Chief of Police of Munich, officially described the camp as "the first concentration camp for political prisoners."[13]
