On the night of 27 February 1933, the Reichstag building was set afire. Marinus van der Lubbe, a Dutch communist, was found guilty of starting the blaze. Hitler proclaimed that the arson marked the start of a communist uprising. The Reichstag Fire Decree, imposed on 28 February 1933, rescinded most civil liberties, including rights of assembly and freedom of the press. The decree also allowed the police to detain people indefinitely without charges. The legislation was accompanied by a propaganda campaign that led to public support for the measure. Violent suppression of communists by the SA was undertaken nationwide and 4,000 members of the Communist Party of Germany were arrested.
The Nazi Party grew significantly during 1921 and 1922, partly through Hitler's oratorical skills, partly through the SA's appeal to unemployed young men, and partly because there was a backlash against socialist and liberal politics in Bavaria as Germany's economic problems deepened and the weakness of the Weimar regime became apparent. The party recruited former World War I soldiers, to whom Hitler as a decorated frontline veteran could particularly appeal, as well as small businessmen and disaffected former members of rival parties. Nazi rallies were often held in beer halls, where downtrodden men could get free beer. The Hitler Youth was formed for the children of party members. The party also formed groups in other parts of Germany. Julius Streicher in Nuremberg was an early recruit and became editor of the racist magazine Der Stürmer. In December 1920, the Nazi Party had acquired a newspaper, the Völkischer Beobachter, of which its leading ideologist Alfred Rosenberg became editor. Others to join the party around this time were Heinrich Himmler and World War I flying ace Hermann Göring.
^ According to Raeder, "Our Air Force could not be counted on to guard our transports from the British Fleets, because their operations would depend on the weather, if for no other reason. It could not be expected that even for a brief period our Air Force could make up for our lack of naval supremacy." Raeder 2001, pp. 324–325. Grand Admiral Karl Dönitz believed air superiority was not enough and admitted, "We possessed neither control of the air or the sea; nor were we in any position to gain it." Dönitz 2012, p. 114.
Losses continued to mount after Stalingrad, leading to a sharp reduction in the popularity of the Nazi Party and deteriorating morale.  Soviet forces continued to push westward after the failed German offensive at the Battle of Kursk in the summer of 1943. By the end of 1943 the Germans had lost most of their eastern territorial gains. In Egypt, Field Marshal Erwin Rommel's Afrika Korps were defeated by British forces under Field Marshal Bernard Montgomery in October 1942. The Allies landed in Sicily in July 1943 and in Italy in September. Meanwhile, American and British bomber fleets based in Britain began operations against Germany. Many sorties were intentionally given civilian targets in an effort to destroy German morale. German aircraft production could not keep pace with losses, and without air cover the Allied bombing campaign became even more devastating. By targeting oil refineries and factories, they crippled the German war effort by late 1944.
The irregular Swiss branch of the Nazi Party also established a number of Party Gaue in that country, most of them named after their regional capitals. These included Gau Basel-Solothurn, Gau Schaffhausen, Gau Luzern, Gau Bern and Gau Zürich. The Gau Ostschweiz (East Switzerland) combined the territories of three cantons: St. Gallen, Thurgau and Appenzell.
The Nazis used propaganda to promulgate the concept of Rassenschande ("race defilement") to justify the need for racial laws. In September 1935, the Nuremberg Laws were enacted. These laws initially prohibited sexual relations and marriages between Aryans and Jews and were later extended to include "Gypsies, Negroes or their bastard offspring". The law also forbade the employment of German women under the age of 45 as domestic servants in Jewish households. The Reich Citizenship Law stated that only those of "German or related blood" could be citizens. Thus Jews and other non-Aryans were stripped of their German citizenship. The law also permitted the Nazis to deny citizenship to anyone who was not supportive enough of the regime. A supplementary decree issued in November defined as Jewish anyone with three Jewish grandparents, or two grandparents if the Jewish faith was followed.
In spite of their rhetoric condemning big business prior to their rise to power, the Nazis quickly entered into a partnership with German business from as early as February 1933. That month, after being appointed Chancellor but before gaining dictatorial powers, Hitler made a personal appeal to German business leaders to help fund the Nazi Party for the crucial months that were to follow. He argued that they should support him in establishing a dictatorship because "private enterprise cannot be maintained in the age of democracy" and because democracy would allegedly lead to communism. He promised to destroy the German left and the trade unions, without any mention of anti-Jewish policies or foreign conquests. In the following weeks, the Nazi Party received contributions from seventeen different business groups, with the largest coming from IG Farben and Deutsche Bank. Historian Adam Tooze writes that the leaders of German business were therefore "willing partners in the destruction of political pluralism in Germany." In exchange, owners and managers of German businesses were granted unprecedented powers to control their workforce, collective bargaining was abolished and wages were frozen at a relatively low level. Business profits also rose very rapidly, as did corporate investment. In addition, the Nazis privatised public properties and public services, but at the same time they increased economic state control through regulations. Hitler believed that private ownership was useful in that it encouraged creative competition and technical innovation, but insisted that it had to conform to national interests and be "productive" rather than "parasitical". Private property rights were conditional upon following the economic priorities set by the Nazi leadership, with high profits as a reward for firms who followed them and the threat of nationalization being used against those who did not. Under Nazi economics, free competition and self-regulating markets diminished, but Hitler's social Darwinist beliefs made him retain business competition and private property as economic engines.
Working from these principles, Hitler carried his party from its inauspicious beginnings in a beer cellar in Munich to a dominant position in world politics 20 years later. The Nazi Party originated in 1919 and was led by Hitler from 1920. Through both successful electioneering and intimidation, the party came to power in Germany in 1933 and governed through totalitarian methods until 1945, when Hitler committed suicide and Germany was defeated and occupied by the Allies at the close of World War II.
The first “bunker,” with two sealed rooms, operated from January 1942 to the end of that year. The second, with four air tight rooms, became redundant in the spring of 1943, but remained standing and was used again in the autumn of 1944 when extra “capacity” was needed for the murder of Hungarian Jews and the liquidation of the ghettos. The second measured about 1.134 square feet. The victims murdered in the “bunkers” were first obliged to undress in temporary wooden barracks erected nearby. Their bodies were taken out of the gas chambers and pushed to pits where they were burned in the open.
During the next two months, some fifty thousand people were arrested on this basis, in what turned into a “frenzy” of political purges and score-settling. In the legal murk of the early Nazi regime, it was unclear who had the power to make such arrests, and so it was claimed by everyone: national, state, and local officials, police and civilians, Party leaders. “Everybody is arresting everybody,” a Nazi official complained in the summer of 1933. “Everybody threatens everybody with Dachau.” As this suggests, it was already clear that the most notorious and frightening destination for political detainees was the concentration camp built by Himmler at Dachau, in Bavaria. The prisoners were originally housed in an old munitions factory, but soon Himmler constructed a “model camp,” the architecture and organization of which provided the pattern for most of the later K.L. The camp was guarded not by police but by members of the S.S.—a Nazi Party entity rather than a state force.
By 1940, the CCI came under the control of the Verwaltung und Wirtschaftshauptamt Hauptamt (VuWHA; Administration and Business office) which was set up under Oswald Pohl. Then in 1942, the CCI became Amt D (Office D) of the consolidated main office known as the SS-Wirtschafts-Verwaltungshauptamt (SS Economic and Administrative Department; WVHA) under Pohl. In 1942, the SS built a network of extermination camps to systematically kill millions of prisoners by gassing. The extermination camps (Vernichtungslager) and death camps (Todeslager) were camps whose primary function was genocide. The Nazis themselves distinguished the concentration camps from the extermination camps. The British intelligence service had information about the concentration camps, and in 1942 Jan Karski delivered a thorough eyewitness account to the government.
