Deportees were brought to Auschwitz crammed in wretched conditions into goods or cattle wagons, arriving near a railway station or at one of several dedicated trackside ramps, including one next to Auschwitz I. The Altejudenrampe (old Jewish ramp), part of the Oświęcim freight railway station, was used from 1942 to 1944 for Jewish transports. Located between Auschwitz I and Auschwitz II, arriving at this ramp meant a 2.5 km journey to Auschwitz II and the gas chambers. Most deportees were forced to walk, accompanied by SS men and a car with a Red Cross symbol that carried the Zyklon B, as well as an SS doctor in case officers were poisoned by mistake. Inmates arriving at night, or who were too weak to walk, were taken by truck. Work on another railway line and Judenrampe (pictured right) between sectors BI and BII in Auschwitz II, was completed in May 1944 for the arrival of Hungarian Jews, who between May and early July 1944 were deported to Auschwitz II at a rate of 12,000 a day. The rails led directly to the area around the gas chambers.
Of those who received numbers at Auschwitz-Birkenau, only 65,000 survived. It is estimated that only about 200,000 people who passed through the Auschwitz camps survived. Michael Bornstein was one of the lucky ones. Decades after the war, he learned from Auschwitz documents kept in Israel that he had survived because he was sick and the Nazis left him behind when they evacuated the camp. He said that he was one of only 52 children under the age of eight who lived.
The permanent exhibitions here will be updated over the next decade to include more evidence focusing on the perpetrators, not just their victims. In the collection’s storage is a box with neat rows of red-handled rubber SS stamps conserved in acid-free boxes. These will eventually go on view. This is part of the long-term plan by the museum, aided by the foundation, which has raised nearly 120 million euros, or about $130 million, about half of it donated by Germany, to ensure conservation in perpetuity.
Auschwitz I, a former Polish army barracks, was the main camp (Stammlager) and administrative headquarters of the camp complex. Intending to use it to house political prisoners, Reichsführer-SS Heinrich Himmler, head of the Schutzstaffel (SS), approved the site in April 1940 on the recommendation of SS-Obersturmbannführer (lieutenant colonel) Rudolf Höss, then of the Concentration Camps Inspectorate. Höss oversaw the development of the camp and served as its first commandant, with SS-Obersturmführer (senior lieutenant) Josef Kramer as his deputy. Around 1,000 m long and 400 m wide, Auschwitz I consisted of 20 brick buildings, six of them two-story; a second story was added to the others in 1943 and eight new blocks were built. The camp housed the SS barracks and by 1943 held 30,000 inmates. The first 30 prisoners arrived on 20 May 1940 after being transported from the Sachsenhausen concentration camp in Oranienburg, Germany. Convicted German criminals (Berufsverbrecher), the men were known as "greens" after the green triangles they were required to wear on their prison clothing. Brought to the camp as functionaries, this group did much to establish the sadism of early camp life, which was directed particularly at Polish inmates, until the political prisoners began to take over their roles.
At Auschwitz I, the majority of the complex has remained intact. The architecture of the camp consisted mostly of pre-existing buildings converted by the Nazis to serve new functions. The preserved architecture, spaces and layout still recall the historical functions of the individual elements in their entirety. The interiors of some of the buildings have been modified to adapt them to commemorative purposes, but the external façades of these buildings remain unchanged.
After the failure of the Beer Hall Putsch in 1923, and his subsequent trial and imprisonment, Hitler decided that the way for the Nazi Party to achieve power was not through insurrection, but through legal and quasi-legal means. This did not sit well with the brown-shirted stormtroopers of the SA, especially those in Berlin, who chafed under the restrictions that Hitler placed on them, and their subordination to the party. This resulted in the Stennes Revolt of 1930-31, after which Hitler made himself the Supreme Commander of the SA, and brought Ernst Röhm back to be their Chief of Staff and keep them in line. The quashing of the SA's revolutionary fervor convinced many businessmen and military leaders that the Nazis had put aside their insurrectionist past, and that Hitler could be a reliable partner 
After conquering Poland, Hitler focused on defeating Britain and France. As the war expanded, the Nazi Party formed alliances with Japan and Italy in the Tripartite Pact of 1940, and honored its 1939 Nazi-Soviet Nonaggression Pact with the Soviet Union until 1941, when Germany launched a massive blitzkrieg invasion of the Soviet Union. In the brutal fighting that followed, Nazi troops tried to realize the long-held goal of crushing the world’s major communist power. After the United States entered the war in 1941, Germany found itself fighting in North Africa, Italy, France, the Balkans and in a counterattacking Soviet Union. At the beginning of the war, Hitler and his Nazi Party were fighting to dominate Europe; five years later they were fighting to exist.
Under Hitler the Nazi Party grew steadily in its home base of Bavaria. It organized strong-arm groups to protect its rallies and meetings. These groups drew their members from war veterans groups and paramilitary organizations and were organized under the name Sturmabteilung (SA). In 1923 Hitler and his followers felt strong enough to stage the Beer Hall Putsch, an unsuccessful attempt to take control of the Bavarian state government in the hope that it would trigger a nationwide insurrection against the Weimar Republic. The coup failed, the Nazi Party was temporarily banned, and Hitler was sent to prison for most of 1924.
The Reich Forestry Office under Göring enforced regulations that required foresters to plant a variety of trees to ensure suitable habitat for wildlife, and a new Reich Animal Protection Act became law in 1933. The regime enacted the Reich Nature Protection Act in 1935 to protect the natural landscape from excessive economic development. It allowed for the expropriation of privately owned land to create nature preserves and aided in long-range planning. Perfunctory efforts were made to curb air pollution, but little enforcement of existing legislation was undertaken once the war began.
In 2015, Flemish journalist Jeroen de Bruyn and Joop van Wijk, Bep Voskuijl's youngest son, wrote a biography, Bep Voskuijl, het zwijgen voorbij: een biografie van de jongste helper van het Achterhuis (Bep Voskuijl, the Silence is Over: A Biography of the Youngest Helper of the Secret Annex), in which they alleged that Bep's younger sister Nelly (1923–2001) could have betrayed the Frank family. According to the book, Bep's sister Diny and her fiancé Bertus Hulsman recollected Nelly telephoning the Gestapo on the morning of 4 August 1944. Nelly had been critical of Bep and their father, Johannes Voskuijl, helping the Jews. (Johannes was the one who constructed the bookcase covering the entrance to the hiding place.) Nelly was a Nazi collaborator between the ages of 19 and 23. Karl Silberbauer, the SS officer who received the phone call and made the arrest, was documented to say that the informer had "the voice of a young woman".
The direct reason for the establishment of the camp was the fact that mass arrests of Poles were increasing beyond the capacity of existing "local" prisons. The first transport of Poles reached KL Auschwitz from Tarnów prison on June 14, 1940. Initially, Auschwitz was to be one more concentration camp of the type that the Nazis had been setting up since the early 1930s. It functioned in this role throughout its existence, even when, beginning in 1942, it also became the largest of the death camps.
In the Soviet Union by 1922 there were 23 concentration camps for the incarceration of persons accused of political offenses as well as criminal offenses. Many corrective labour camps were established in northern Russia and Siberia, especially during the First Five-Year Plan, 1928–32, when millions of rich peasants were driven from their farms under the collectivization program. The Stalinist purges of 1936–38 brought additional millions into the camps—said to be essentially institutions of slavery.
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.
Most of the POWs died within weeks. “When it was time to get up in the morning, those who were alive moved, and around them would be two or three dead people,” one Russian survivor says in the 2005 book Auschwitz: A New History by Laurence Rees. “Death at night, death in the morning, death in the afternoon. There was death all the time.” The prisoners built the barracks at Birkenau in a rush, laying a single course of bricks on poorly made foundations. The flood of Soviet POWs overwhelmed the already crowded camp. Pressure to “eliminate” people—the Nazi euphemism—grew.
The Nazi Terror Begins After Adolf Hitler became chancellor of Germany in January 1933, he moved quickly to turn Germany into a one-party dictatorship and to organize the police power necessary to enforce Nazi policies. He persuaded his Cabinet to declare a state of emergency and end individual freedoms, including freedom of press, speech, and assembly. Individuals lost the right to privacy, which meant that officials could read people's mail, listen in on telephone conversations, and search private homes without a warrant.
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.
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. 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 camps were liberated by the Allied forces between 1944 and 1945. The first major camp, Majdanek, was discovered by the advancing Soviets on July 23, 1944. Auschwitz was liberated, also by the Soviets, on January 27, 1945; Buchenwald by the Americans on April 11; Bergen-Belsen by the British on April 15; Dachau by the Americans on April 29; Ravensbrück by the Soviets on the same day; Mauthausen by the Americans on May 5; and Theresienstadt by the Soviets on May 8. Treblinka, Sobibór, and Bełżec were never liberated, but were destroyed by the Nazis in 1943. Colonel William W. Quinn of the U.S. 7th Army said of Dachau: "There our troops found sights, sounds, and stenches horrible beyond belief, cruelties so enormous as to be incomprehensible to the normal mind."
