Birkenau (Auschwitz II) was established in October 1941, three kilometers from Auschwitz. Exterminations in Birkenau began in March 1942. There were four gas chambers in the camp that used Zyklon B gas. Until November 1944 the camp functioned as a factory for mass murder, receiving transports from all over Europe. Most of those brought to the camp were Jews and nearly all were immediately sent to the gas chambers. Only a small percentage was selected for labor in the camp itself, labor in munitions plants at satellite camps, or the “medical” experiments of Dr. Josef Mengele and his staff. In the spring and summer of 1944, the rate of extermination was increased as the Jews of Hungary and the Lodz ghetto were brought to the camp.
Cornelis Suijk—a former director of the Anne Frank Foundation and president of the U.S. Center for Holocaust Education Foundation—announced in 1999 that he was in the possession of five pages that had been removed by Otto Frank from the diary prior to publication; Suijk claimed that Otto Frank gave these pages to him shortly before his death in 1980. The missing diary entries contain critical remarks by Anne Frank about her parents' strained marriage and discuss Frank's lack of affection for her mother.[76] Some controversy ensued when Suijk claimed publishing rights over the five pages; he intended to sell them to raise money for his foundation. The Netherlands Institute for War Documentation, the formal owner of the manuscript, demanded the pages be handed over. In 2000 the Dutch Ministry of Education, Culture and Science agreed to donate US$300,000 to Suijk's foundation, and the pages were returned in 2001. Since then, they have been included in new editions of the diary.[77]

Kamil Bedkowski, 33, worked as an art conservator in Britain for eight years, even restoring ceiling frescoes at Windsor Castle. Now he is on the team shoring up the crumbling brick barracks of Birkenau where thousands slept at a time, crammed into decaying three-level wooden bunks. “This is the most challenging project I’ve ever worked on,” he said.
The Germans reaffirmed their alliance with Italy and signed non-aggression pacts with Denmark, Estonia, and Latvia whilst trade links were formalised with Romania, Norway, and Sweden.[76] Foreign Minister Joachim von Ribbentrop arranged in negotiations with the Soviet Union a non-aggression pact, the Molotov–Ribbentrop Pact, signed in August 1939.[77] The treaty also contained secret protocols dividing Poland and the Baltic states into German and Soviet spheres of influence.[78]
By mid-1942, the majority of those being sent by the Nazis to Auschwitz were Jews. Upon arriving at the camp, detainees were examined by Nazi doctors. Those detainees considered unfit for work, including young children, the elderly, pregnant women and the infirm, were immediately ordered to take showers. However, the bathhouses to which they marched were disguised gas chambers. Once inside, the prisoners were exposed to Zyklon-B poison gas. Individuals marked as unfit for work were never officially registered as Auschwitz inmates. For this reason, it is impossible to calculate the number of lives lost in the camp.
One night in the autumn of 1944, two Frenchwomen—Loulou Le Porz, a doctor, and Violette Lecoq, a nurse—watched as a truck drove in through the main gates of Ravensbrück, the Nazi concentration camp for women. “There was a lorry,” Le Porz recalled, “that suddenly arrives and it turns around and reverses towards us. And it lifts up and it tips out a whole pile of corpses.” These were the bodies of Ravensbrück inmates who had died doing slave labor in the many satellite camps, and they were now being returned for cremation. Talking, decades later, to the historian and journalist Sarah Helm, whose new book, “Ravensbrück: Life and Death in Hitler’s Concentration Camp for Women” (Doubleday), recounts the stories of dozens of the camp’s inmates, Le Porz says that her reaction was simple disbelief. The sight of a truck full of dead bodies was so outrageous, so out of scale with ordinary experience, that “if we recount that one day, we said to each other, nobody would believe us.” The only way to make the scene credible would be to record it: “If one day someone makes a film they must film this scene. This night. This moment.”
"It's utterly impossible for me to build my life on a foundation of chaos, suffering and death," she wrote on July 15, 1944. "I see the world being slowly transformed into a wilderness; I hear the approaching thunder that, one day, will destroy us too. I feel the suffering of millions. And yet, when I look up at the sky, I somehow feel that everything will change for the better, that this cruelty too shall end, that peace and tranquility will return once more."
In 1944 we were sent on a death march from Birkenau to Oranienburg and from there to Buchenwald. Then to a quarry, where we were ordered to drill into the mountains to make some sort of secret city. From there we walked back to Buchenwald. Whoever was incapable of walking was shot. From there, big trains took us to Theresienstadt just as the Soviets were bombing the rails. We could sense that the Germans were almost destroyed. For 17 days we had no water, no food, nothing. Despite the hardship I was doing OK compared to others. I still had the capability to clamber on to the cattle trains without help.
Adolf Hitler replaces elected officials in state governments with Nazi appointees. One of the first steps in establishing centralized Nazi control in Germany is the elimination of state governments. Hermann Goering, a leading Nazi, becomes minister-president of Prussia, the largest German state. By 1935, state administrations are transferred to the central government in Berlin.
In most of the camps discovered by the Soviets, almost all the prisoners had already been removed, leaving only a few thousand alive—7,000 inmates were found in Auschwitz, including 180 children who had been experimented on by doctors.[45] Some 60,000 prisoners were discovered at Bergen-Belsen by the British 11th Armoured Division,[46] 13,000 corpses lay unburied, and another 10,000 died from typhus or malnutrition over the following weeks.[47] The British forced the remaining SS guards to gather up the corpses and place them in mass graves.[48]
The term was in use before the rise of the party as a colloquial and derogatory word for a backward peasant, an awkward and clumsy person. It derived from Ignaz, a shortened version of Ignatius,[20][21] which was a common name in the Nazis' home region of Bavaria. Opponents seized on this, and the long-existing Sozi, to attach a dismissive nickname to the National Socialists.[21][22]
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.[64] 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.
In the spring of 1941, the SS—along with doctors and officials of the T-4 Euthanasia Program—introduced the Action 14f13 programme meant for extermination of selected concentration camp prisoners.[31] The Inspectorate of the Concentration Camps categorized all files dealing with the death of prisoners as 14f, and those of prisoners sent to the T-4 gas chambers as 14f13. Under the language regulations of the SS, selected prisoners were designated for "special treatment (German: Sonderbehandlung) 14f13". Prisoners were officially selected based on their medical condition; namely, those permanently unfit for labor due to illness. Unofficially, racial and eugenic criteria were used: Jews, the handicapped, and those with criminal or antisocial records were selected.[32]:p.144 For Jewish prisoners there was not even the pretense of a medical examination: the arrest record was listed as a physician's "diagnosis".[32]:pp. 147–148 In early 1943, as the need for labor increased and the gas chambers at Auschwitz became operational, Heinrich Himmler ordered the end of Action 14f13.[32]:p.150
