Animal welfare in Nazi Germany

There was widespread support for animal welfare in Nazi Germany[1] (German: Tierschutz im nationalsozialistischen Deutschland) among the country's leadership. Adolf Hitler and his top officials took a variety of measures to ensure animals were protected.[2]

Several Nazis were environmentalists, and species protection and animal welfare were significant issues in the Nazi regime.[3] Heinrich Himmler made an effort to ban the hunting of animals.[4] Hermann Göring was a professed animal lover and conservationist,[5] who, on instructions from Hitler, committed Germans who violated Nazi animal welfare laws to concentration camps. In his private diaries, Nazi Propaganda Minister Joseph Goebbels described Hitler as a vegetarian whose hatred of the Jewish religion in large part stemmed from the ethical distinction this faith drew between the value of humans and the value of animals; Goebbels also mentions that Hitler planned to discourage slaughterhouses in the German Reich following the conclusion of World War II.[6] Moreover, animal testing was permitted in Nazi Germany.[7][8][9]

The current animal welfare laws in Germany were initially introduced by the Nazis.[10]

Measures

edit

At the end of the nineteenth century, kosher butchering and vivisection (animal experimentation) were the main concerns of the German animal welfare movement. The Nazis adopted these concerns as part of their political platform.[11] According to Boria Sax, the Nazis rejected anthropocentric reasons for animal protection—animals were to be protected for their own sake.[12] In 1927, a Nazi representative to the Reichstag called for actions against cruelty to animals and kosher butchering.[11]

In 1931, the Nazi Party (then a minority in the Reichstag) proposed a ban on vivisection, but the ban failed to attract support from other political parties. By 1933, after Hitler had ascended to the Chancellery and the Nazis had consolidated control of the Reichstag, the Nazis immediately held a meeting to enact the ban on vivisection. On April 21, 1933, almost immediately after the Nazis came to power, the parliament began to pass laws for the regulation of animal slaughter.[11] On April 21, a law was passed concerning the slaughter of animals; no animals were to be slaughtered without anesthetic.

On April 24, Order of the Prussian Ministry of the Interior was enacted regarding the slaughter of poikilotherms.[13] Nazi Germany was the first nation to ban vivisection.[14] A law imposing total ban on vivisection was enacted on August 16, 1933, by Hermann Göring as the prime minister of Prussia.[15] He announced an end to the "unbearable torture and suffering in animal experiments" and said that those who "still think they can continue to treat animals as inanimate property" will be sent to concentration camps.[11] On August 28, 1933, Göring announced in a radio broadcast:[16]

An absolute and permanent ban on vivisection is not only a necessary law to protect animals and to show sympathy with their pain, but it is also a law for humanity itself.... I have therefore announced the immediate prohibition of vivisection and have made the practice a punishable offense in Prussia. Until such time as punishment is pronounced the culprit shall be lodged in a concentration camp.[16]

Göring prohibited vivisection and said that those who "still think they can continue to treat animals as inanimate property" would be sent to concentration camps.[11]

Göring also banned commercial animal trapping and imposed severe restrictions on hunting. He prohibited boiling of lobsters and crabs. In one incident, he sent a fisherman to a concentration camp[16] for cutting up a bait frog.[14]

On November 24, 1933, Nazi Germany enacted another law called Reichstierschutzgesetz (Reich Animal Protection Act), for protection of animals.[17][18] This law listed many prohibitions against the use of animals, including their use for filmmaking and other public events causing pain or damage to health,[19] feeding fowls forcefully and tearing out the thighs of living frogs.[20] The two principals (Ministerialräte) of the German Ministry of the Interior, Clemens Giese and Waldemar Kahler, who were responsible for drafting the legislative text,[18] wrote in their juridical comment from 1939, that by the law the animal was to be "protected for itself" ("um seiner selbst willen geschützt"), and made "an object of protection going far beyond the hitherto existing law" ("Objekt eines weit über die bisherigen Bestimmungen hinausgehenden Schutzes").[21]

On February 23, 1934, a decree was enacted by the Prussian Ministry of Commerce and Employment which introduced education on animal protection laws at primary, secondary and college levels.[13] On 3 July 1934, a law Das Reichsjagdgesetz (The Reich Hunting Law) was enacted which limited hunting. The act also created the German Hunting Society with a mission to educate the hunting community in ethical hunting. July 1, 1935, another law Reichsnaturschutzgesetz (Reich Nature Conservation Act) was passed to protect nature.[18] According to an article published in Kaltio, one of the main Finnish cultural magazines, Nazi Germany was the first state in the world to place the wolf under protection.[22] Nazi Germany "introduced the first legislation for the protection of wolves."[23]

In 1934, Nazi Germany hosted an international conference on animal welfare in Berlin.[24] On March 27, 1936, an order on the slaughter of living fish and other poikilotherms was enacted. On March 18 the same year, an order was passed on afforestation and on protection of animals in the wild.[13] On September 9, 1937, a decree was published by the Ministry of the Interior which specified guidelines for the transportation of animals.[25] In 1938, the Nazis introduced animal protection as a subject to be taught in public schools and universities in Germany.[24]

On June 28, 1935, Nazi Germany enacted legislation that created a separate category in Paragraph 175 for "fornication with animals" and penalized with up to five years in prison.

Effectiveness

edit

Although various laws were enacted for animal protection, the extent to which they were enforced has been questioned. The law enacted by Hermann Göring on August 16, 1933, banning vivisection was revised by a decree of September 5 of that year, with more lax provisions, then allowing the Reich Interior Ministry to distribute permits to some universities and research institutes to conduct animal experiments under conditions of anesthesia and scientific need.[8] According to Pfugers Archiv für die Gesamte Physiologie (Pfugers Archive for the Total Physiology), a science journal at that time, there were many animal experiments during the Nazi regime.[7] In 1936, the Tierärztekammer (Chamber of Veterinarians) in Darmstadt filed a formal complaint against the lack of enforcement of the animal protection laws on those who conducted illegal animal testing.[9]

Potentially related were the Nazi government's policies to achieve "nutritional freedom" by discouraging the population's consumption of certain foods. The discouraged foods were not restricted to animal products, and some animal products such as quark were actively encouraged, but overall these policies resulted in a decline in consumption of 17 percent for meat, 21 percent for milk, and 46 percent for eggs between 1927 and 1937.[26]

Hunting in Nazi Germany

edit

Hunting was a common hobby among the leaders of the Nazi regime, Gauleiters, members of the Nazi extermination squads and extermination camp staff.[27] A non-exhaustive list of hunters among notable Nazis includes: Among Hitler's cabinet ministers: Hermann Göring,[28] Heinrich Himmler,[29][30][31] Joachim von Ribbentrop,[29] Wilhelm Keitel,[32] Hans Frank[33][34]; Among Gauleiters and other senior Nazi politicians: Arthur Greiser,[35] Erich Koch,[30][31] Karl Kaufmann[36][31], Max Amann[37]; Among SS and Waffen-SS generals: Reinhard Heydrich,[38][39] Oswald Pohl,[40][31] Odilo Globocnik,[31] Gottlob Berger,[41][31] Sepp Dietrich,[42] Werner Lorenz,[43] Karl Wolff,[29][31] Erich von dem Bach-Zelewski,[31] Otto Rasch[44]; Among top army commanders: Erwin Rommel,[45] Heinz Guderian,[46][47] Eduard Dietl,[48] Adolf Galland[49]; Among the Nazi staff in Auschwitz: Rudolf Höss,[50] Richard Baer,[51][52] Eduard Wirths,[53] Horst Schumann,[54] Victor Capesius[55].

Hermann Göring, was an avid hunter since childhood.[28] He liked to hunt mostly deer and displayed his hunting trophies. He sometimes declared that he wants to shoot "the strongest stag in Europe".[56] For Göring, the hunt and the forest represented the authentic and pure life.[57] In May 1933, Göring was appointed Reich Master of the Hunt (Reichsjägermeister).[58] In this capacity he produced and financed an international hunting exhibition in Berlin in 1937, which Hitler visited on November 6th that year[59]. In early 1933, Hitler gave Göring a special fund through which he could pursue his passions.[60] With this fund he built his hunting estate: Carinhall, in the Schorfheide Reserve.[60][58] The reserve even appeared in legislation for the protection of nature in a way that coincided with Göring's enjoyment of hunting.[60] Goering held many hunting parties in Carinhall. In the last weeks of the war, he spent his time in Carinhall, and ordered his men to shoot the bisons in the reserve.[61] In the Buchenwald concentration camp, the Nazis established a falconry park and a hunting hall in honor of Göring. There was a game reserve in the place where elk, donkeys, wild boars, mouflon sheep, pheasants, foxes and other animals were kept.[62]

Many of those who devoted their working hours to slaughtering people, preferred to spend their leisure hours hunting animals. Hitler himself said in a conversation on September 7, 1942 that hunting for German officers is like jewelry for women.[63] At a meeting held by Martin Bormann, Hitler's secretary, with the Nazi governors in early 1942, the Gauleiters were so eager to tell their hunting stories that Bormann was unable to conduct a discussion of the serious issues at hand.[27] On July 21, 1941, the SS officer and member of the Einsatzkommando, Felix Landau, noted in his diary: "The men got a day off, and some of them went hunting."[64] At times the hunting of animals could develop into the killing of Jews.[65] The Hocker Album shows images of the Nazi staff of Auschwitz engaging in hunting at their leisure time.[66]

The American conservationist Aldo Leopold visited Germany in and described that: "Every acre of forestland in Germany, whether state or privately owned, is cropped for game."[67] After the occupation of Poland, its forests became hunting grounds for the Germans.[68]

The Nazi regime encouraged whaling. Under Hitler's rule, Germany became for the first time in its history a nation that engages in whaling on a large scale.[69] and Germany's share of whaling in the Antarctic increased from 2% in 1934 to 19% in 1937.[70] Hitler even claimed in 1942 that the whaling industry could provide more products to the German economy, and that it was important to continue developing it.[71]

Controversies

edit

Tolerance towards animal experimentation

edit

Despite promoting tolerance towards animals, the government of Nazi Germany would often sanction animal testing and preferred using animals instead of humans when conducting biological experiments.[72] Animal rights activist Boria Sax argues in his book Animals in the Third Reich: Pets, Scapegoats, and the Holocaust that the Nazis manipulated attitudes towards animal protection to conform to their own symbolic system. Presumably, by equating the National Socialist German Workers Party with "nature", the Nazis reduced ethical issues to biological questions.[73]

Policies regarding non-Nazi activists

edit

Scholars who argue that the Nazis were not authentic supporters of animal rights point out that the Nazi regime disbanded some organizations advocating environmentalism or animal protection. However these organizations, such as the 100,000-member strong Friends of Nature, were disbanded because they advocated political ideologies that were illegal under Nazi law.[74] For example, the Friends of Nature was officially non-partisan, but activists from the major rival party, the Social Democratic Party, were prominent among its leaders.[75]
