Persecution of the Catholic Church in Germany followed the Nazi takeover.[417] Hitler moved quickly to eliminate political Catholicism, rounding up functionaries of the Catholic-aligned Bavarian People's Party and Catholic Centre Party, which along with all other non-Nazi political parties ceased to exist by July.[418] The Reichskonkordat (Reich Concordat) treaty with the Vatican was signed in 1933, amid continuing harassment of the church in Germany.[314] The treaty required the regime to honour the independence of Catholic institutions and prohibited clergy from involvement in politics.[419] Hitler routinely disregarded the Concordat, closing all Catholic institutions whose functions were not strictly religious.[420] Clergy, nuns and lay leaders were targeted, with thousands of arrests over the ensuing years, often on trumped-up charges of currency smuggling or immorality.[421] Several Catholic leaders were targeted in the 1934 Night of the Long Knives assassinations.[422][423][424] Most Catholic youth groups refused to dissolve themselves and Hitler Youth leader Baldur von Schirach encouraged members to attack Catholic boys in the streets.[425] Propaganda campaigns claimed the church was corrupt, restrictions were placed on public meetings and Catholic publications faced censorship. Catholic schools were required to reduce religious instruction and crucifixes were removed from state buildings.[426]

Nazi flags: The Nazi Party used a right-facing swastika as their symbol and the red and black colours were said to represent Blut und Boden ("blood and soil"). Another definition of the flag describes the colours as representing the ideology of National Socialism, the swastika representing the Aryan race and the Aryan nationalist agenda of the movement; white representing Aryan racial purity; and red representing the socialist agenda of the movement. Black, white and red were in fact the colours of the old North German Confederation flag (invented by Otto von Bismarck, based on the Prussian colours black and white and the red used by northern German states). In 1871, with the foundation of the German Reich the flag of the North German Confederation became the German Reichsflagge ("Reich flag"). Black, white and red became the colours of the nationalists through the following history (for example World War I and the Weimar Republic).
Uniquely at Auschwitz, prisoners were tattooed with a serial number, on their left breast for Soviet prisoners of war[97] and on the left arm for civilians.[98] Categories of prisoner were distinguishable by triangular pieces of cloth (German: Winkel) sewn onto on their jackets below their prisoner number. Political prisoners (Schutzhäftlinge or Sch), mostly Poles, had a red triangle, while criminals (Berufsverbrecher or BV) were mostly German and wore green. Asocial prisoners (Asoziale or Aso), which included vagrants, prostitutes and the Roma, wore black. Purple was for Jehovah's Witnesses (Internationale Bibelforscher-Vereinigung or IBV)'s and pink for gay men, who were mostly German.[99] An estimated 5,000–15,000 gay men prosecuted under German Penal Code Section 175 (proscribing sexual acts between men) were detained in concentration camps, of which an unknown number were sent to Auschwitz.[100] Jews wore a yellow badge, the shape of the Star of David, overlaid by a second triangle if they also belonged to a second category. The nationality of the inmate was indicated by a letter stitched onto the cloth. A racial hierarchy existed, with German prisoners at the top. Next were non-Jewish prisoners from other countries. Jewish prisoners were at the bottom.[101]
The Sturmabteilung (SA; Storm Detachment; Brownshirts), founded in 1921, was the first paramilitary wing of the NSDAP; their initial assignment was to protect Nazi leaders at rallies and assemblies.[227] They also took part in street battles against the forces of rival political parties and violent actions against Jews and others.[228] Under Ernst Röhm's leadership the SA grew by 1934 to over half a million members—4.5 million including reserves—at a time when the regular army was still limited to 100,000 men by the Versailles Treaty.[229]

The first concentration camps in Germany were established soon after Hitler's appointment as chancellor in January 1933. In the weeks after the Nazis came to power, The SA (Sturmabteilungen; commonly known as Storm Troopers), the SS (Schutzstaffel; Protection Squadrons—the elite guard of the Nazi party), the police, and local civilian authorities organized numerous detention camps to incarcerate real and perceived political opponents of Nazi policy.
As early as February 1933, Hitler announced that rearmament must begin, albeit clandestinely at first, as to do so was in violation of the Versailles Treaty. On 17 May 1933, Hitler gave a speech before the Reichstag outlining his desire for world peace and accepted an offer from American President Franklin D. Roosevelt for military disarmament, provided the other nations of Europe did the same.[53] When the other European powers failed to accept this offer, Hitler pulled Germany out of the World Disarmament Conference and the League of Nations in October, claiming its disarmament clauses were unfair if they applied only to Germany.[54] In a referendum held in November, 95 percent of voters supported Germany's withdrawal.[55]
By then, Auschwitz was serving as both a slave labor facility and a death camp. As the Germans brought more and more Jews from all over Europe to the sprawling complex, SS doctors selected the fittest for work. Other prisoners were sent directly to Birkenau’s gas chambers for what was euphemistically known as a special action. “Was present for first time at a special action at 3 a.m. By comparison Dante’s Inferno seems almost a comedy,” SS doctor Johann Paul Kremer wrote in his diary on September 2, 1942. Camp records show the transport he observed contained 957 Jews from France; only 12 men and 27 women were selected for work.
What of those immigrants who became citizens, or those beleaguered minorities to whom the United States granted the privileges of citizenship? Despite an avowed declaration of constitutional equality, citizenship was under its own separate-but-equal doctrine. Until 1924, Native Americans were considered “nationals” and not citizens. After the Spanish-American War of 1898, Puerto Ricans and Filipinos were legally classified as “non-citizen nationals.” Most infamously, the 1857 Dred Scott decision held that African Americans were not citizens, and even after the Civil War, black people were legally relegated to third-class status. The Nazis took interest in all of this; the second Nuremburg Law confined citizenship to that person who “is exclusively a national of German blood, or racially related blood.” Jews were denaturalized, rendered subjects. The U.S. precedent laid out how to create a hierarchy of citizens, nationals, and subjects. Tiered citizenship and the capricious revocations of civil rights were of great interest to Nazi intellectuals.
The hair of 12 year-old Lili had not been cut since her early childhood. When she and her family were forced to leave their home in Târgu-Mureş and move to the ghetto, Lili’s mother, Rivka, knew she would not be able to care properly for her daughter’s hair in the ghetto. Chopping off Lili’s two long, beautiful braids, she promised that they would be given to the neighbors for safekeeping.Within six weeks, Lili and her mother were murdered at Auschwitz.
As the German leader (Führer) of Nazi Germany, Hitler began moving Nazi armies into neighboring countries. When Germany attacked Poland, World War II started. Western countries like France, Belgium, and the Netherlands were occupied and to be treated by Germany as colonies. However, in Eastern countries, such as Poland and the Soviet Union, the Nazis planned to kill or enslave the Slavic peoples, so that German settlers could take their land.
The prisoners put up various forms of resistance to the tyranny of the camp. Resistance organisations helped inmates to obtain medicine and food, documented Nazi crimes, supported attempts to escape and sabotage, tried to put political prisoners into positions of responsibility, and prepared for an uprising. A total of 667 prisoners escaped from Auschwitz, but 270 of them were caught in the vicinity of the camp and immediately executed. The best-known escape was that of two Slovak Jews, Alfred Wetzler and Walter Rosenberg (Rudolf Vrba) (link in Czech). They managed to cross into Slovakia and to tell Jewish leaders - and through them the world - about the terrible reality of Auschwitz, about which they wrote an extensive report. On the 7th of October 1944, there was an uprising by the Sonderkommando working in the gas chambers. The prisoners managed to destroy one of the gas chambers, and thus to hinder the extermination process. All the rebels died. A group of young female prisoners was also executed for having smuggled gunpowder to the rebels from the factory in Monowitz.
All of the extermination camps were thoroughly organised and resembled industrial plants to an alarming degree. However, only Auschwitz-Birkenau, with its advanced gassing facilities and crematoria, was marked by high technology. In crematoria I and II there were elevators from the gas chambers underground, where the Jews were murdered, to the crematoria, where the bodies were burned.
It is not white supremacy that differentiates America from Nazi Germany, but rather the constitutional architecture of this country—a democratic system tested, broken, remade, rewritten. Racism in the United States is counterbalanced by an emancipatory spirit. The Constitution enshrined slavery, but this same Constitution was transformed as a result of the bloodiest war in U.S. history, which ended the Southern slave empire. The Civil War was a second American founding, and the passage of the Thirteenth, Fourteenth, and Fifteenth amendments advanced the American spirit of equality before the law. Even amid the racist terror that lasted long after the Civil War, African Americans made room in the United States to fight for their freedom, equality, and dignity. Nazi Germany, by contrast, was a totalitarian state, and its express objective was the erasure of the Jewish people. These differences cannot be minimized.
Beginning in April 1933, scores of measures defining the status of Jews and their rights were instituted.[49] These measures culminated in the establishment of the Nuremberg Laws of 1935, which stripped them of their basic rights.[50] The Nazis would take from the Jews their wealth, their right to intermarry with non-Jews, and their right to occupy many fields of labour (such as law, medicine, or education). Eventually the Nazis declared the Jews as undesirable to remain among German citizens and society.[51]
Adolf Hitler, the party's leader since 1921, was appointed Chancellor of Germany by President Paul von Hindenburg on 30 January 1933. Hitler rapidly established a totalitarian regime[12][13][14][15] known as the Third Reich. Following the defeat of the Third Reich at the conclusion of World War II in Europe, the party was "declared to be illegal" by the Allied powers,[16] who carried out denazification in the years after the war.
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]
Large segments of the Nazi Party, particularly among the members of the Sturmabteilung (SA), were committed to the party's official socialist, revolutionary and anti-capitalist positions and expected both a social and an economic revolution when the party gained power in 1933.[43] In the period immediately before the Nazi seizure of power, there were even Social Democrats and Communists who switched sides and became known as "Beefsteak Nazis": brown on the outside and red inside.[44] The leader of the SA, Ernst Röhm, pushed for a "second revolution" (the "first revolution" being the Nazis' seizure of power) that would enact socialist policies. Furthermore, Röhm desired that the SA absorb the much smaller German Army into its ranks under his leadership.[43] Once the Nazis achieved power, Röhm's SA was directed by Hitler to violently suppress the parties of the left, but they 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, in what came to be known as the Night of the Long Knives.[46]
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.[25] 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.[25] 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.[26][27] The British intelligence service had information about the concentration camps, and in 1942 Jan Karski delivered a thorough eyewitness account to the government.
