Germany implemented the persecution of the Jews in stages. Following Adolf Hitler's appointment as German Chancellor in January 1933, the regime built a network of concentration camps in Germany for political opponents and those deemed "undesirable", starting with Dachau on 22 March 1933.[5] After the passing of the Enabling Act on 24 March,[6] which gave Hitler plenary powers, the government began isolating Jews from civil society, which included a boycott of Jewish businesses in April 1933 and enacting the Nuremberg Laws in September 1935. On 9–10 November 1938, during Kristallnacht (the "Night of Broken Glass"), Jewish businesses and other buildings were ransacked, smashed or set on fire throughout Germany and Austria, which Germany had annexed in March that year. After Germany invaded Poland in September 1939, triggering World War II, the regime set up ghettos to segregate Jews. Eventually thousands of camps and other detention sites were established across German-occupied Europe.
Hilberg's analysis of the steps that led to the destruction of European Jews revealed that it was "an administrative process carried out by bureaucrats in a network of offices spanning a continent".[108] Hilberg divides this bureaucracy into four components or hierarchies: the Nazi Party, the civil service, industry, and the Wehrmacht armed forces – but their cooperation is viewed as "so complete that we may truly speak of their fusion into a machinery of destruction".[109] For Hilberg, the key stages in the destruction process were: definition and registration of the Jews; expropriation of property; concentration into ghettoes and camps; and, finally, annihilation.[110] Hilberg gives an estimate of 5.1 million as the total number of Jews killed. He breaks this figure down into three categories: Ghettoization and general privation: over 800,000; open-air shootings: over 1,300,000; extermination camps: up to 3,000,000.[111]
Treatment inside the concentration camps were horrible. Prisoners were given tiny rations of food and forced into physical labor. They often slept more than three to a bed without pillows or blankets, even in the winter months. In many concentration camps, Nazi doctors conducted medical experiments on prisoners against their will, in many cases killing the prisoners in the process.
Begin thought settling the score with Mengele would show Palestinian leaders (and the Israeli public) that they would have to pay a price for harming Israelis. His attitude was reflected in a message he sent to President Ronald Reagan when he sent the Israeli Army into Lebanon in 1982, saying that he felt as if “I have sent an army to Berlin to wipe out Hitler in the bunker.”
Beginning with the British air raids on Cologne in May of 1942, the Allies launched a strategic bombing campaign that would target cities and industrial plants across the Reich for the next three years. In the summer of 1942, Germany and its allies focused on the Soviet Union unsuccessfully. The Soviet Union gained the dominant role, which it would maintain for the rest of the war.
After Germany’s loss in WWI, the Treaty of Versailles punished Germany by placing tough restrictions on the country. The treaty made Germany take full responsibility for the war, reduced the extent of German territory, severely limited the size and placement of their armed forces, and forced Germany to pay the allied powers reparations. These restrictions not only increased social unrest but, combined with the start of the Great Depression, collapsed the German economy as inflation rose alongside unemployment.
In addition to active help, many clergymen also protested the mistreatment and deportations of Jews as violations of divine and human laws. The Catholic pastor of St. Hedwig’s Cathedral in Berlin, Bernard Lichtenburg, prayed publicly for the Jews until his arrest and death on the way to Dachau. The rescue work of priests of all Christian denominations is well-documented in postwar literature.

An Israeli historian Dina Porat claimed that the Final Solution, i.e.: "the systematic overall physical extermination of Jewish communities one after the other – began in Lithuania" during the massive German chase after the Red Army across the Baltic states in Reichskommissariat Ostland.[53] The subject of the Holocaust in Lithuania has been analysed by Konrad Kweit from USHMM who wrote: "Lithuanian Jews were among the first victims of the Holocaust [beyond the eastern borders of occupied Poland]. The Germans carried out the mass executions [...] signaling the beginning of the 'Final Solution'."[54] About 80,000 Jews were killed in Lithuania by October (including in formerly Polish Wilno) and about 175,000 by the end of 1941 according to official reports.[53]
Over the decades that followed, ordinary Germans struggled with the Holocaust’s bitter legacy, as survivors and the families of victims sought restitution of wealth and property confiscated during the Nazi years. Beginning in 1953, the German government made payments to individual Jews and to the Jewish people as a way of acknowledging the German people’s responsibility for the crimes committed in their name.

The nature and timing of the decisions that led to the Final Solution is an intensely researched and debated aspect of the Holocaust. The program evolved during the first 25 months of war leading to the attempt at "murdering every last Jew in the German grasp".[5] Most historians agree, wrote Christopher Browning, that the Final Solution cannot be attributed to a single decision made at one particular point in time.[5] "It is generally accepted the decision-making process was prolonged and incremental."[6] In 1940, following the Fall of France, Adolf Eichmann devised the Madagascar Plan to move Europe's Jewish population to the French colony, but the plan was abandoned for logistical reasons, mainly a naval blockade.[7] There were also preliminary plans to deport Jews to Palestine and Siberia.[8] In 1941, wrote Raul Hilberg, in the first phase of the mass murder of Jews, the mobile killing units began to pursue their victims across occupied eastern territories; in the second phase, stretching across all of German-occupied Europe, the Jewish victims were sent on death trains to centralized extermination camps built for the purpose of systematic implementation of the Final Solution.[9]

Life in the camps was a living hell. As described by Judah Pilch in “Years of the Holocaust: The Factual Story,” which appears in The Jewish Catastrophe in Europe, a typical day in the life of a concentration camp inmate began at dawn, when they were roused from their barracks which housed 300-800 inmates each. Their “beds” were bunks of slatted wood two and three tiers high. Frequently three to four prisoners shared each bunk, not permitting space enough for them to stretch out for normal sleep. The inmates were organized into groups to go to the toilets, marched to a distribution center for a breakfast consisting of some bread and a liquid substitute for tea or coffee, and then sent out to work for 10-14 hours in mines, factories, and road or airfield building, often in sub-zero weather or the severe heat of summer. They were subjected to constant physical and emotional harassment and beating. The inmates’ food rations did not permit survival for very long. Those who resisted orders of the guards were shot on the spot. Numerous roll calls were held to assure that no prisoners had escaped. If one did attempt an escape, all of the inmates suffered for it.

The Yad Vashem Law authorizes Yad Vashem "to confer honorary citizenship upon the Righteous Among the Nations, and if they have died, the commemorative citizenship of the State of Israel, in recognition of their actions". Anyone who has been recognized as "Righteous" is entitled to apply to Yad Vashem for the certificate. If the person is no longer alive, their next of kin is entitled to request that commemorative citizenship be conferred on the Righteous who has died.
Freund and I walked the path of the tunnel, over the large hummock of earth, out toward the surrounding pines. Not such a long distance on foot, perhaps, but positively heroic when one considered that it had been dug, night after night, by chained men who had spent their daylight hours laboring at their unthinkable task, subsisting on nothing more than gruel.
As the unsuspecting people were herded off the train and ordered into separate lines, SS officers shouted in German, "Zwillinge!" (Twins!). Parents were forced to make a quick decision. Unsure of their situation, already being separated from family members when forced to form lines, seeing barbed wire, smelling an unfamiliar stench -- was it good or bad to be a twin?
Mengele used Auschwitz as an opportunity to continue his anthropological studies and research into heredity, using inmates for human experimentation.[2] His medical procedures showed no consideration for the health, safety, or physical and emotional suffering of the victims.[2][3] He was particularly interested in identical twins, people with heterochromia iridum (eyes of two different colors), dwarfs, and people with physical abnormalities.[2] A grant was provided by the Deutsche Forschungsgemeinschaft (German Research Foundation), at the request of von Verschuer, who received regular reports and shipments of specimens from Mengele. The grant was used to build a pathology laboratory attached to Crematorium II at Auschwitz II-Birkenau.[38] Dr. Miklós Nyiszli, a Hungarian Jewish pathologist who arrived in Auschwitz on 29 May 1944, performed dissections and prepared specimens for shipment in this laboratory.[39] The twin research was in part intended to prove the supremacy of heredity over environment and thus strengthen the Nazi premise of the superiority of the Aryan race.[40] Nyiszli and others reported that the twin studies may also have been motivated by an intention to increase the reproduction rate of the German race by improving the chances of racially desirable people having twins.[41]
