Reich Security Main Office in the context of "Ernst Kaltenbrunner"

Law enforcement in Germany is constitutionally vested solely with the states, which is one of the main features of the German political system.

Policing has always been a responsibility of the German states even after 1871 when the country was unified. The 1919 constitution of the Weimar Republic did provide for the possibility of creating a national police force, should the necessity arise, but it was only in the Nazi era that Gestapo (Secret State Police) were unified under central control and a national police force created (the Reich Security Main Office—Reichssicherheitshauptamt, or RSHA). The police became a tool of the centralized state and the Nazi party.Following the defeat of 1945, Germany was divided; in 1949 the three western zones were turned into the new West Germany, while the Soviet zone became East Germany. Each country pursued a different path concerning law enforcement.

Reinhard Heydrich, the commander of the German Reich Security Main Office (RSHA), the acting Reichsprotektor of the Protectorate of Bohemia and Moravia and a principal architect of the Holocaust, was assassinated during the Second World War in a coordinated operation by the Czechoslovak resistance. The assassination attempt, code-named Operation Anthropoid, was carried out by resistance operatives Jozef Gabčík and Jan Kubiš on 27 May 1942. Heydrich was wounded in the attack and died of his injuries on 4 June.

The operatives who carried out the assassination were soldiers of the Czechoslovak Army who were prepared and trained by the British Special Operations Executive (SOE) with the approval of the Czechoslovak government-in-exile, led by Edvard Beneš. The Czechoslovaks undertook the operation to help confer legitimacy on the government-in-exile, and to exact retribution for Heydrich's brutal rule. The operation was the only verified government-sponsored assassination of a senior Nazi leader during the war. Heydrich's death led to a wave of reprisals by SS troops, including the destruction of villages and mass killings of civilians, including the Lidice massacre.

The Geheime Staatspolizei ([ɡəˈhaɪmə ˈʃtaːtspoliˌtsaɪ] , lit. 'Secret State Police'), abbreviated Gestapo ([ɡəˈstaːpo] ), was the official secret police of Nazi Germany and in German-occupied Europe.

The force was created by Hermann Göring in 1933 by combining the various political police agencies of Prussia into one organisation. On 20 April 1934, oversight of the Gestapo passed to the head of the Schutzstaffel (SS), Heinrich Himmler, who was also appointed Chief of German Police by Hitler in 1936. Instead of being exclusively a Prussian state agency, the Gestapo became a national one as a sub-office of the Sicherheitspolizei (SiPo; Security Police). From 27 September 1939, it was administered by the Reich Security Main Office (RSHA). It became known as Amt (Dept) 4 of the RSHA and was considered a sister organisation to the Sicherheitsdienst (SD; Security Service).

Kriminalpolizei (English: Criminal Police), often abbreviated as Kripo, is the German name for a criminal investigation department. This article deals with the agency during the Nazi era.

In Nazi Germany, the Kripo consisted of the Reich Criminal Police Department (RKPA), which in 1939 became Department V of the Reich Security Main Office (RSHA). There were criminal investigation centers directly subordinated to RKPA as well as criminal investigation divisions of the local state and municipal police departments. In 1943 both the latter became directly subordinated to the criminal investigation centers. The personnel consisted of detectives in the junior, executive, and female careers, as well as criminal investigation employees.

Sicherheitsdienst (German: [ˈzɪçɐhaɪtsˌdiːnst] , "Security Service"), full title Sicherheitsdienst des Reichsführers-SS ("Security Service of the Reichsführer-SS"), or SD, was the intelligence agency of the SS and the Nazi Party in Nazi Germany. Established in 1931, the SD was the first Nazi intelligence organization and the Gestapo (formed in 1933) was considered its sister organization through the integration of SS members and operational procedures. The SD was administered as an independent SS office between 1933 and 1939. That year, the SD was transferred over to the Reich Security Main Office (Reichssicherheitshauptamt; RSHA), as one of its seven departments. Its first director, Reinhard Heydrich, intended for the SD to bring every single individual within the Third Reich's reach under "continuous supervision".

Following Germany's defeat in World War II, the tribunal at the Nuremberg trials officially declared that the SD was a criminal organisation, along with the rest of Heydrich's RSHA (including the Gestapo) both individually and as branches of the SS in the collective. Heydrich was assassinated in 1942; his successor, Ernst Kaltenbrunner, was convicted of war crimes and crimes against humanity at the Nuremberg trials, sentenced to death and hanged in 1946.

Reinhard Tristan Eugen Heydrich (/ˈhaɪdrɪk/; German: [ˈʁaɪnhaʁt ˈtʁɪstan ˈʔɔʏɡn̩ ˈhaɪdʁɪç] ; 7 March 1904 – 4 June 1942) was a high-ranking German SS and police official in Nazi Germany as well as one of the principal architects of the Holocaust. He held the rank of SS-Obergruppenführer und General der Polizei. Many historians regard Heydrich as one of the most sinister figures within the Nazi regime. Adolf Hitler described him as "the man with the iron heart."

Heydrich was chief of the Reich Security Main Office (including the Gestapo, Kripo, and SD). He was also Stellvertretender Reichsprotektor (Deputy Reich-Protector) of Bohemia and Moravia. He served as president of the International Criminal Police Commission (ICPC, now known as Interpol) and chaired the January 1942 Wannsee Conference which formalised plans for the "Final Solution to the Jewish question"—the deportation and genocide of all Jews in German-occupied Europe.

The Reich Ministry for the Occupied Eastern Territories (RMfdbO; German: Reichsministerium für die besetzten Ostgebiete), commonly known as the Ostministerium, (pronounced [ˈɔstminɪsˌteːʁiʊm] ; "Eastern Ministry") was a ministry of Nazi Germany responsible for occupied territories in the Baltic states and Soviet Union from 1941 to 1945. Alfred Rosenbergserved as Reichsminister with Alfred Meyer as his deputy during its existence.

The Ostministerium was created by Adolf Hitler shortly after the German invasion of the Soviet Union to control the vast areas captured and projected for capture by the Wehrmacht in the Baltic states, Belarus, Ukraine, and Russia. Two Reichskommissariats were established: Ostland and Ukraine, while two more were planned, Moskowien and Kaukasien, but the Wehrmacht never established firm possession of the areas designated and German civilian control never developed there. The Ostministerium was involved in the development and implementation of Generalplan Ost, which fell under its jurisdiction, along with the Reich Commission for the Consolidation of German Nationhood, the Reich Security Main Office, and the SS Race and Settlement Main Office. It was one of the main agencies that oversaw the Holocaust in the Soviet Union.

The Wannsee Conference (German: Wannseekonferenz, German pronunciation: [ˈvanzeːkɔnfeˌʁɛnt͡s] ) was a meeting of senior government officials of Nazi Germany and Schutzstaffel (SS) leaders, held in the Berlin suburb of Wannsee on 20 January 1942. The purpose of the conference, called by the director of the Reich Security Main Office SS-Obergruppenführer Reinhard Heydrich, was to ensure the co-operation of administrative leaders of various government departments in the implementation of the Final Solution to the Jewish Question, whereby most of the Jews of German-occupied Europe would be deported to occupied Poland and murdered. Conference participants included representatives from several government ministries, including state secretaries from the Foreign Office, the justice, interior, and state ministries, and representatives from the SS. In the course of the meeting, Heydrich outlined how European Jews would be rounded up and sent to extermination camps in the General Government (the occupied part of Poland), where they would be murdered.

Discrimination against Jews began immediately after the Nazi seizure of power on 30 January 1933. Violence and economic pressure were used by the Nazi regime to encourage Jews to voluntarily leave the country. After the invasion of Poland in September 1939, the extermination of European Jews began, first through mobile death squads like the Einsatzgruppen, and the murders continued and accelerated after the invasion of the Soviet Union in June 1941. On 31 July 1941, Hermann Göring gave written authorization to Heydrich to prepare and submit a plan for a "total solution of the Jewish question" in territories under German control and to coordinate the participation of all involved government organisations. At the Wannsee Conference, Heydrich emphasised that once the deportation process was complete, the fate of the deportees would become an internal matter under the purview of the SS. A secondary goal was to arrive at a definition of who was Jewish.
