, Copenhagen 17 October 1943 As a trained lawyer,
Heydrich and
Himmler counted on Best throughout the 1930s for his skills in conceptualizing and justifying Nazi law, which helped provide the SS-police apparatus with its nearly unrestricted power over German society. Best became a member of the
Academy for German Law () and the chairman of its Committee on Police Law, where he worked alongside the future SS-
Oberführer Reinhard Höhn. Best appeared dedicated to the national-racial cause of the Nazis and typified the ideal administrator for its terror apparatus. Historian Frank Trentmann wrote that "Best personified the technocratic Nazi, cold and functional". Correspondingly, Best quickly rose to the rank of SS-
Brigadeführer and became chief of Department 1 of the
Gestapo, which was in charge of organization, administration, and legal affairs. He was a deputy to
Reinhard Heydrich. Both men saw the Gestapo as actually working on "behalf of the German people" through both "ethnic and political purification". By 1934,
Ernst Röhm's increasing political influence over the powerful Nazi paramilitary organisation, the
Sturmabteilung (SA), was seen as a threat by Hitler, who ordered its elimination as an independent political force. On 30 June 1934, the SS and Gestapo implemented Hitler's plan and carried out mass arrests that continued for two days. While Heydrich coordinated the operation from Berlin, Best was sent to Munich to "oversee a wave of arrests" in the southern part of Germany. The purge became known as the
Night of the Long Knives. Up to 200 people, including Röhm, were killed in the action. Even though Canadian historian
Robert Gellately wrote that most Gestapo men were not Nazis, at the same time, they were not opposed to the Nazi regime and willingly served in whatever task they were called upon to perform. Over time, membership in the Gestapo included ideological indoctrination, particularly once Best assumed a leading role for training in April 1936. Employing biological metaphors, Best emphasized a doctrine that encouraged members of the Gestapo to view themselves as 'doctors' to the national body in the struggle against "pathogens" and "diseases"; among the implied sicknesses were "communists, Freemasons, and the churches—and above and behind all these stood the Jews." Heydrich thought along similar lines and advocated both defensive and offensive measures on the part of the Gestapo, so as to prevent any subversion or destruction of the Nazi body. On 27 September 1939, the SD and SiPo (made up of the Gestapo and the
Kripo) were folded into the new
Reich Security Main Office (
Reichssicherheitshauptamt; RSHA), which was placed under Heydrich's control. Best was made head of Amt I (Department I) of the RSHA: Administration and Legal. That department dealt with the legal and personnel issues/matters of the SS and security police. Heydrich and
Heinrich Himmler relied on Best to develop and legally justify the activities against enemies of the state, especially those aimed at Jews. In 1939 Best became one of the directors of Heydrich's foundation, the
Stiftung Nordhav, and was placed in command of choosing leaders for the
Einsatzgruppen task forces and their subgroups (the
Einsatzkommandos) from among educated people with military experience; many of them former members of the
Freikorps. Werner Best lost a power struggle within the RSHA, and had to leave Berlin in 1940. With the military grade of War Administration Chief (
Kriegsverwaltungschef), Best was appointed chief of the Section "Administration" (
Abteilung Verwaltung) of the Administration Staff (
Verwaltungsstab, Dr Schmid) under then (
Militärbefehlshaber in Frankreich or MBF) "Military Commander in France", General
Otto von Stülpnagel in
occupied France. Best held this position until 1942. In his efforts as the RSHA emissary in France, Best's unit drew up radical plans for a total reorganization of Western Europe based on racial principles; he sought to unite
Netherlands,
Flanders and French territory north of the river
Loire into the Reich, turn
Wallonia and
Brittany into German protectorates, merge
Northern Ireland with the
Irish Free State, create a decentralized British federation and break
Spain into independent entities of
Galicia,
Basque Country and
Catalonia. After the November 1942
Telegram Crisis, Best was appointed the
Third Reich's Plenipotentiary (
Reichsbevollmächtigter) in
occupied Denmark, which gave him supervisory control of civilian affairs there. Meanwhile, King
Christian X, unlike most heads of state under
Nazi German occupation, remained in office, along with the Danish Parliament, cabinet (a coalition of national unity) and courts. When the Nazis attempted to deport Denmark's Jews, the cabinet and Christian X objected. Best kept his position in Denmark until the end of the war in May 1945, even after the German military commander,
Hermann von Hanneken—who had been encouraged by Hitler to rule Denmark with an iron hand—had assumed direct control over its administration on 29 August 1943. ==Administration by the Permanent Secretaries==
