Auschwitz II (or "Birkenau") was completed in early 1942. Birkenau was built approximately 1.9 miles (3 km) away from Auschwitz I and was the real killing center of the Auschwitz death camp. It was in Birkenau where the dreaded selections were carried out on the ramp and where the sophisticated and camouflaged gas chambers laid in waiting. Birkenau, much larger than Auschwitz I, housed the most prisoners and included areas for women and Gypsies.

Adolf Hitler envisioned the eventual extermination of what he called “the Jewish plague,” but the Führer didn’t draw up the plans for the gas chambers or the timetables for the transports. And while it was senior SS officials who gave general instructions about how the camps should function, it was ordinary Germans, soldiers and civilians alike, who worked out the deadly details. “There wasn’t a grand strategy in 1940 that the camp would accrue a number of functions and ultimately become a death camp,” Dwork says. “I do not see it as planned at all. Way led to way, and step led to step.”
During the German invasion of the Soviet Union the Nazis began the first mass killings of Jews. Between June and September 1941, the Einsatzgruppen supported by local collaborators murdered hundreds of thousands of Jews across Latvia, Lithuania, Estonia and the Soviet Union. Having observed the killings, Adolf Eichmann ordered a more efficient method of killing the Jews of Europe be developed.
Goods and raw materials were also taken. In France, an estimated 9,000,000 tonnes (8,900,000 long tons; 9,900,000 short tons) of cereals were seized during the course of the war, including 75 percent of its oats. In addition, 80 percent of the country's oil and 74 percent of its steel production were taken. The valuation of this loot is estimated to be 184.5 billion francs. In Poland, Nazi plunder of raw materials began even before the German invasion had concluded.[296]
Other Nazis—especially those at the time associated with the party's more radical wing such as Gregor Strasser, Joseph Goebbels and Heinrich Himmler—rejected Italian Fascism, accusing it of being too conservative or capitalist.[126] Alfred Rosenberg condemned Italian Fascism for being racially confused and having influences from philosemitism.[127] Strasser criticised the policy of Führerprinzip as being created by Mussolini and considered its presence in Nazism as a foreign imported idea.[128] Throughout the relationship between Nazi Germany and Fascist Italy, a number of lower-ranking Nazis scornfully viewed fascism as a conservative movement that lacked a full revolutionary potential.[128]

Concentration camp, internment centre for political prisoners and members of national or minority groups who are confined for reasons of state security, exploitation, or punishment, usually by executive decree or military order. Persons are placed in such camps often on the basis of identification with a particular ethnic or political group rather than as individuals and without benefit either of indictment or fair trial. Concentration camps are to be distinguished from prisons interning persons lawfully convicted of civil crimes and from prisoner-of-war camps in which captured military personnel are held under the laws of war. They are also to be distinguished from refugee camps or detention and relocation centres for the temporary accommodation of large numbers of displaced persons.
The swastika has come to represent the Nazis because of it's use on the Nazi flag. The Nazi flag, created by Hitler, has a red background, and a white circle with a black right-facing swastika in the middle. But the swastika predates the Nazis. The earliest consistent use of swastika motifs on record date back to the Stone Age. The swastika has been used as a religious symbol in many different religions. The word swastika comes from a Sanskrit word (svastika) meaning any lucky or auspicious object, and in particular a mark made on persons and things to denote good luck. Although, because of it's association with the Nazis, public showing of the swastika and other Nazi symbols, in Germany, is illegal, except for scholarly or religious reasons.
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.
By the end of the war, the number of people who had died in the concentration camps, from all causes—starvation, sickness, exhaustion, beating, shooting, gassing—was more than eight hundred thousand. The figure does not include the hundreds of thousands of Jews gassed on arrival at Auschwitz. If the K.L. were indeed a battlefront, as the Death’s-Head S.S. liked to believe, the deaths, in the course of twelve years, roughly equalled the casualties sustained by the Axis during the Battle of Stalingrad, among the deadliest actual engagements of the war. But in the camps the Nazis fought against helpless enemies. Considered as prisons, too, the K.L. were paradoxical: it was impossible to correct or rehabilitate people whose very nature, according to Nazi propaganda, was criminal or sick. And as economic institutions they were utterly counterproductive, wasting huge numbers of lives even as the need for workers in Germany became more and more acute.
Both in public and in private, Hitler expressed disdain for capitalism, arguing that it holds nations ransom in the interests of a parasitic cosmopolitan rentier class.[262] He opposed free market capitalism because it "could not be trusted to put national interests first," and he desired an economy that would direct resources "in ways that matched the many national goals of the regime," such as the buildup of the military, building programs for cities and roads, and economic self-sufficiency.[229] Hitler also distrusted capitalism for being unreliable due to its egotism and he preferred a state-directed economy that maintains private property and competition but subordinates them to the interests of the Volk.[262]

Under Nazism, with its emphasis on the nation, individualism was denounced and instead importance was placed upon Germans belonging to the German Volk and "people's community" (Volksgemeinschaft).[272] Hitler declared that "every activity and every need of every individual will be regulated by the collectivity represented by the party" and that "there are no longer any free realms in which the individual belongs to himself".[273] Himmler justified the establishment of a repressive police state, in which the security forces could exercise power arbitrarily, by claiming that national security and order should take precedence over the needs of the individual.[274]

Officials and lawyers in the Third Reich were also intrigued by anti-miscegenation statutes, because the policing of sex was necessary to cleanse the Aryan race. Hitler, who had been largely asexual during his crucial years as a failing painter in Vienna, was obsessed with sex and blood. The United States at the time was a global leader in banning mixed marriages, going so far as to criminally punish those who defied the law. (Many of these laws were not struck down in the United States until the Supreme Court’s 1967 Loving v. Virginia case.) The Prussian Memorandum explicitly invoked U.S. laws that promoted segregation to maintain racial purity, and the sexual morality of white women in particular. Similarly, the third Nuremburg Law expressly forbid marriages and extra-marital relations between Germans and Jews, and promised hard labor in prison for law-breakers. The more one reads about the American and Nazi fixation on race, the more evident it becomes that at the very core of racist ideology is a primal fear of sexual inadequacy, of pollution, of mixing. Racial nationalism, the ideology of the Nazis, took this idea to its logical end.
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.
