Historians differ on the date of the decision to murder Jews systematically, the so-called “final solution to the Jewish question.” There is debate about whether there was one central decision or a series of regional decisions in response to local conditions. In either case, when Germany attacked the Soviet Union, its former ally, in June of 1941, the Nazis began the systematic killing of Jews.
Heinrich Himmler witnessed this killing process and decided to develop a cheaper, more effective method of murder that would not be as upsetting for the perpetrators. The Nazis were already using gas to murder the mentally and physically disabled; this was now to be applied to the Jews as well. This section will discuss the the Wannsee Conference and the ‘Final Solution to the Jewish Question’.
In France Jews under Fascist Italian occupation in the southeast fared better than the Jews of Vichy France, where collaborationist French authorities and police provided essential support to the understaffed German forces. The Jews in those parts of France under direct German occupation fared the worst. Although allied with Germany, the Italians did not participate in the Holocaust until Germany occupied northern Italy after the overthrow of Fascist leader Benito Mussolini in 1943.
The Soviet Army reached Auschwitz on January 27, 1945. By that time, an estimated 1,500,000 Jews, along with 500,000 Polish prisoners, Soviet POWs and Gypsies, had perished there. As the Western Allies pushed into Germany in the spring of 1945, they liberated Buchenwald, Bergen-Belsen, and Dachau. Now the full horror of the twelve-year Nazi regime became apparent as British and American soldiers, including Supreme Commander Dwight D. Eisenhower, viewed piles of emaciated corpses and listened to vivid accounts given by survivors.
In August 1944, they were discovered and deported to Nazi concentration camps. They were long thought to have been betrayed, although there are indications that their discovery may have been accidental, that the police raid had actually targeted "ration fraud". Of the eight people, only Otto Frank, the oldest, survived the war. Anne died when she was 15 years old in Bergen-Belsen, from typhus. The exact date of her death is unknown, and has long been believed to be in early March, a few weeks before the prisoners were liberated by British troops in April 1945. However, research in 2015 indicated that Anne may have died in February.
With this police infrastructure in place, opponents of the Nazis were terrorized, beaten, or sent to one of the concentration camps the Germans built to incarcerate them. Dachau, just outside of Munich, was the first such camp built for political prisoners. Dachau's purpose changed over time and eventually became another brutal concentration camp for Jews.
The ideology of Nazism brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum (living space) for the Germanic people. Nazi Germany attempted to obtain this new territory by attacking Poland and the Soviet Union, intending to deport or kill the Jews and Slavs living there, who were considered by the Nazis to be inferior to the Aryan master race.
