Holocaust 101

Camps
After the 1932 elections it became clear to the Nazi leaders that they would never be able to secure a majority of the votes and that they would have to rely on other means to gain power. Leading up to the 1933 elections, the Nazis began intensifying acts of violence to wreak havoc among the opposition. At the same time, with cooperation from local authorities, they set up camps as concentration centers within Germany. One of the first was Dachau, which opened in March 1933. These early camps were meant to hold, torture, or kill only political prisoners, such as Communists and Social Democrats. Eventually, the Nazis imprisoned Jews, Gypsies, Jehovah's Witnesses, homosexuals, critical journalists, and other undesirables.

Ghettos
After the invasion of Poland, the Nazis created ghettos (small neighbourhoods, historically referring to Jewish neighbourhoods, generally segregated from the rest of a city) to which Jews were confined, until they were eventually shipped to death camps and killed. The Warsaw Ghetto was the largest, with 380,000 people and the Łódź Ghetto, the second largest, holding about 160,000, but ghettos were instituted in many cities. The ghettos were established throughout 1940 and 1941, and were immediately turned into immensely crowded prisons; though the Warsaw Ghetto contained 30% of the population of Warsaw, it occupied only about 2.4% of city's area, averaging 9.2 people per room. From 1940 through 1942, disease (especially typhoid fever) and starvation killed hundreds of thousands of Jews confined in the ghettos.

On July 19, 1942, Heinrich Himmler ordered the start of the deportations of Jews from the ghettos to the death camps. On July 22, 1942, the deportations from the Warsaw Ghetto inhabitants began; in the next 52 days (until September 12, 1942) about 300,000 people were transported by train to the Treblinka extermination camp from Warsaw alone. Many other ghettos were completely depopulated.

The Devil's Arithmetic: The Final Solution
Mass killings of over 1 million Jews occurred before the plans of the Final Solution were fully implemented in 1942, but it was only with the decision to eradicate the entire Jewish population that the extermination camps were built and industrialized mass slaughter of Jews began in earnest. This decision to systematically kill the Jews of Europe was made by the time of, or at the Wannsee conference, which took place in Berlin, in the Wannsee Villa on January 20, 1942. During the conference, there was a discussion held by a group of Nazi officials to decide on the "Final Solution of the Jewish Question". The records and minutes of this meeting were found intact by the Allies at the end of the war and served as valuable evidence during the Nuremberg Trials. By spring of 1942, Operation Reinhard began the systematic extermination of the Jews, although hundreds of thousands already had been killed by death squads and in mass pogroms. In Heinrich Himmler's speech at the Posen Conference of October 6, 1943, Himmler, for the first time, clearly elucidated to all assembled leaders of the Reich, in frank and brutal terms, what the "Final Solution" actually referred to.

In December 1941, the Nazis opened Chelmno, the first of what would soon be seven extermination camps, dedicated entirely to mass extermination on an industrial scale, as opposed to the labor or concentration camps. Over three million Jews would die in these extermination camps. The method of killing at these camps was by poison gas (Zyklon B or carbon monoxide), usually in "gas chambers", although many prisoners were killed in mass shootings and by other means. The bodies of those killed were destroyed in crematoria (except at Sobibór where they were cremated on outdoor pyres), and the ashes buried or scattered.

In 1942, the Nazis began this most destructive phase of the Holocaust, with Aktion Reinhard, opening the extermination camps of Belzec, Sobibór, and Treblinka. More than 1.7 million Jews were killed at the three Aktion Reinhard camps by October 1943. The largest death camp built was Auschwitz-Birkenau, which had both a labor camp (Auschwitz) and an extermination camp (Birkenau); the latter possessing four gas chambers and crematoria. This camp was responsible for the deaths of an estimated 1.6 million Jews (including about 438,000 Jews from Hungary in the course of a few months), 75,000 Poles and gay men, and some 19,000 Roma. At the peak of operations, Birkenau's gas chambers killed approximately 8,000 a day.

Upon arrival in these camps, all valuables were taken from the prisoners, and the women had to have their hair cut off. According to a Nazi document, the hair was to be used for the manufacture of stockings. Prisoners were divided into two groups: those too weak for work were immediately executed in gas chambers (which were sometimes disguised as showers) and their bodies burned, while others were first used for slave labor in factories or industrial enterprises located in the camp or nearby. Shoes, stockings, and anything else of value was recycled for use in products to support the war effort, regardless of whether or not a prisoner was sent to death. Some prisoners were forced to work in the collection and disposal of corpses, and to extract gold teeth from the dead.

Resistance
Due to the organization and overwhelming military might of the Nazi German state and its supporters, few Jews and other Holocaust victims were able to resist the killings. There are, however, many cases of attempts at resistance in one form or another, and over a hundred armed Jewish uprisings.
The largest instance of organized Jewish resistance was the Warsaw Ghetto Uprising, from April to May of 1943, as the final deportation from the Ghetto to the death camps was about to commence, the ZOB and ZZW fighters rose up against the Nazis. Most of the resistors were killed, but the few who did survive the war are currently residing in Israel. There were also other Ghetto Uprisings, though none were successful against the German military.

There were also major resistance efforts in three of the extermination camps. In August 1943, an uprising also took place at the Treblinka extermination camp. Many buildings were burnt to the ground, and seventy inmates escaped to freedom, but 1,500 were killed. Gassing operations were interrupted for a month. In October 1943, another uprising took place at Sobibór extermination camp. This uprising was more successful; 11 SS men and a number of Ukrainian guards were killed, and roughly 300 of the 600 inmates in the camp escaped, with about 50 surviving the war. The escape forced the Nazis to close the camp. On October 7, 1944, the Jewish Sonderkommandos (those prisoners kept separate from the main camp and involved in the operation of the gas chambers and crematoria) at Auschwitz staged an uprising. Female prisoners had smuggled in explosives from a weapons factory, and Crematorium IV was partly destroyed by an explosion. The prisoners then attempted a mass escape, but all 250 were killed soon after.
There were a number of Jewish partisan groups operating in many countries (see Eugenio Calò for the story of a Jewish Italian partisan). Also, Jewish volunteers from the Palestinian Mandate, most famously Hannah Szenes (pronounced se-nesh), parachuted into Europe in a failed attempt to organize resistance.

Liberation
As the armies of the Allies closed in on the Reich at the end of 1944, the Nazis decided to abandon the extermination camps, moving or destroying evidence of the atrocities they had committed there. The Nazis marched prisoners, already sick after months or years of violence and starvation, for tens of miles in the snow to train stations; then transported for days at a time without food or shelter in freight trains with open carriages; and forced to march again at the other end to the new camp. Prisoners who lagged behind or fell were shot. The largest and most well known of the death marches took place in January 1945, when the Soviet army advanced on Poland. Nine days before the Soviets arrived at the death camp at Auschwitz, the SS guards marched 60,000 prisoners out of the camp toward Wodzislaw, 56 km (35 mi) away, where they were put on freight trains to other camps. Around 15,000 died on the way. In total, around 100,000 Jews died during these death marches.

In July 1944, the first major Nazi camp, Majdanek, was discovered by the advancing Soviets, who eventually liberated Auschwitz in January 1945. In most of the camps discovered by the Soviets, the prisoners had already been transported away by death marches, leaving only a few thousand prisoners alive. Concentration camps were also liberated by American and British forces, including Bergen-Belsen concentration camp on April 15, 1945. Some 60,000 prisoners were discovered at the camp, but 10,000 died from disease or malnutrition within a few weeks of liberation.

The Victims
While the victims of the Holocaust were primarily Jews, the Nazis also persecuted and slaughtered the members of other groups they considered inferior, undesirable or dangerous, including Poles and other Slavic peoples such as Russians, Belarusians and Serbs, Bosniaks, Roma & Sinti (also known as Gypsies), and some Africans, Asians and others who did not belong to the "Aryan race"; the mentally ill and the physically disabled; homosexuals; and political opponents and religious dissidents such as communists, trade unionists, Freemasons and Jehovah's Witnesses.

The victims of the Holocaust were generally described by the Nazis as "undesirables," "enemies of the state", "asocial elements," and "moral degenerates," labels that went hand-in-hand with their term Untermensch ("sub-human").
