Around 7,000 SS personnel were posted to Auschwitz during the war. Of these, 4 percent of SS personnel were officers and 26 percent were non-commissioned officers, while the remainder were rank-and-file members. Camp guards were members of the SS-Totenkopfverbände (Death's Head Units). 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. SS personnel at the camp included 200 women, who worked as guards, nurses, or messengers. About 120 SS personnel were assigned to the gas chambers and lived on site at the crematoria.
To complete this mission, Hitler ordered the construction of death camps. Unlike concentration camps, which had existed in Germany since 1933 and were detention centers for Jews, political prisoners and other perceived enemies of the Nazi state, death camps existed for the sole purpose of killing Jews and other “undesirables,” in what became known as the Holocaust.
From the first escape on 6 July 1940 of Tadeusz Wiejowski, at least 802 prisoners (757 men and 45 women) tried to escape from the camp, according to Polish historian Henryk Świebocki. He writes that most escapes were attempted from work sites outside the camp.[f] Of these, 144 were successful and the fate of 331 is unknown. Four Polish prisoners—Eugeniusz Bendera (a car mechanic at the camp), Kazimierz Piechowski, Stanisław Gustaw Jaster, and a priest, Józef Lempart—escaped successfully on 20 June 1942. After breaking into a warehouse, the four dressed as members of the SS-Totenkopfverbände (the SS units responsible for concentration camps), armed themselves, and stole an SS staff car, which they drove unchallenged through the main gate, greeting several officers with "Heil Hitler!" as they drove past. On 21 July 1944, Polish inmate Jerzy Bielecki dressed in an SS uniform and, using a faked pass, managed to cross the camp's gate with his Jewish girlfriend, Cyla Cybulska (known as Cyla Stawiska), pretending that she was wanted for questioning. Both survived the war. For having saved her, Bielecki was recognized by Yad Vashem as Righteous Among the Nations.
From 1928 onward, the Nazi Party's growth into a large national political movement was dependent on middle class support, and on the public perception that it "promised to side with the middle classes and to confront the economic and political power of the working class."  The financial collapse of the white collar middle-class of the 1920s figures much in their strong support of Nazism. Although the Nazis continued to make appeals to "the German worker," historian Timothy Mason concludes that "Hitler had nothing but slogans to offer the working class."
On 20 July 1932, the Prussian government was ousted by a coup, the Preussenschlag; a few days later at the July 1932 Reichstag election the Nazis made another leap forward, polling 37.4% and becoming the largest party in parliament by a wide margin. Furthermore, the Nazis and the Communists between them won 52% of the vote and a majority of seats. Since both parties opposed the established political system and neither would join or support any ministry, this made the formation of a majority government impossible. The result was weak ministries governing by decree. Under Comintern directives, the Communists maintained their policy of treating the Social Democrats as the main enemy, calling them "social fascists", thereby splintering opposition to the Nazis. Later, both the Social Democrats and the Communists accused each other of having facilitated Hitler's rise to power by their unwillingness to compromise.
However, after the Nazis' "Seizure of Power" in 1933, Röhm and the Brown Shirts were not content for the party to simply carry the reigns of power. Instead, they pressed for a continuation of the "National Socialist revolution" to bring about sweeping social changes, which Hitler, primarily for tactical reasons, was not willing to do at that time. He was instead focused on rebuilding the military and reorienting the economy to provide the rearmament necessary for invasion of the countries to the east of Germany, especially Poland and Russia, to get the Lebensraum ("living space") he believed was necessary to the survival of the Aryan race. For this, he needed the co-operation of not only the military, but also the vital organs of capitalism, the banks and big businesses, which he would be unlikely to get if Germany's social and economic structure was being radically overhauled. Röhm's public proclamation that the SA would not allow the "German Revolution" to be halted or undermined caused Hitler to announce that "The revolution is not a permanent condition." The unwillingness of Röhm and the SA to cease their agitation for a "Second Revolution", and the unwarranted fear of a "Röhm putsch" to accomplish it, were factors behind Hitler's purging of the SA leadership in the Night of the Long Knives in July 1934.
When the Nazis came to power in Germany, they quickly moved to suppress all real and potential opposition. The general public was intimidated by the arbitrary psychological terror that was used by the special courts (Sondergerichte). Especially during the first years of their existence when these courts "had a strong deterrent effect" against any form of political protest.
