Obergruppenführer in the context of "Reinhard Heydrich"

Einsatzgruppen (German: [ˈaɪnzatsˌɡʁʊpm̩], lit. 'deployment groups'; also 'task forces') were Schutzstaffel (SS) paramilitary death squads of Nazi Germany that were responsible for mass murder, primarily by shooting, during World War II (1939–1945) in German-occupied Europe. The Einsatzgruppen had an integral role in the implementation of the so-called "Final Solution to the Jewish question" (Die Endlösung der Judenfrage) in territories conquered by Nazi Germany, and were involved in the murder of much of the intelligentsia and cultural elite of Poland, including members of the Catholic priesthood. Almost all of the people they murdered were civilians, beginning with the intelligentsia and swiftly progressing to Soviet political commissars, Jews, and Romani people, as well as actual or alleged partisans throughout Eastern Europe.

Under the direction of Reichsführer-SS Heinrich Himmler and the supervision of SS-Obergruppenführer Reinhard Heydrich, the Einsatzgruppen operated in territories occupied by the Wehrmacht (German armed forces) following the invasion of Poland in September 1939 and the invasion of the Soviet Union in June 1941. The Einsatzgruppen worked hand-in-hand with the Order Police battalions on the Eastern Front to carry out operations ranging from the murder of a few people to operations which lasted over two or more days, such as the massacre at Babi Yar (with 33,771 Jews murdered in two days), and the Rumbula massacre (with about 25,000 Jews murdered in two days of shooting). As ordered by Nazi leader Adolf Hitler, the Wehrmacht cooperated with the Einsatzgruppen, providing logistical support for their operations, and participated in the mass murders. Historian Raul Hilberg estimates that between 1941 and 1945 the Einsatzgruppen, related agencies, and foreign auxiliary personnel murdered more than two million people, including 1.3 million of the 5.5 to 6 million Jews murdered during the Holocaust.

The 11th SS Panzer Army (SS-Panzer-Armeeoberkommando 11) was little more than a paper army formed in February 1945 by Heinrich Himmler while he was commander of Army Group Vistula. (The army was officially listed as the 11th Army but it was also known as SS Panzer-Armeeoberkommando 11 and is often referred to in English sources as the 11th SS Panzer Army.)

Military historian Antony Beevor writes that when the 11th SS Panzer Army was created the available units at best could constitute a corps, but 'panzer army', observed Hans-Georg Eismann, 'has a better ring to it'. It also allowed Himmler to promote SS officers to senior staff and field commands within the formation. Obergruppenführer Felix Steiner was named its commander.

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.

Otto Adolf Eichmann (/ˈaɪkmən/ EYEKH-mən; German pronunciation: [ˈʔɔto ˈʔaːdɔlf ˈʔaɪçman] ; 19 March 1906 – 1 June 1962) was a German-Austrian official of the Nazi Party, an officer of the Schutzstaffel (SS), a convicted war criminal, and one of the major organisers of the Holocaust. He participated in the January 1942 Wannsee Conference, at which the implementation of the genocidal Final Solution to the Jewish Question was planned. Following this, he was tasked by SS-Obergruppenführer Reinhard Heydrich with facilitating and managing the logistics involved in the mass deportation of millions of Jews to Nazi ghettos and Nazi extermination camps across German-occupied Europe. He was captured and detained by the Allies in 1945, but escaped and eventually settled in Argentina. In May 1960, he was tracked down and apprehended by Israel's Mossad intelligence agency, and put on trial before the Supreme Court of Israel. The highly publicised Eichmann trial resulted in his conviction in Jerusalem, following which he was executed by hanging in 1962.

After doing poorly in school, Eichmann briefly worked for his father's mining company in Austria, where the family had moved in 1914. He worked as a travelling oil salesman beginning in 1927, and joined both the Nazi Party and the SS in 1932. He returned to Germany in 1933, where he joined the Sicherheitsdienst (SD, "Security Service"); there he was appointed head of the department responsible for Jewish affairs – especially emigration, which the Nazis encouraged through violence and economic pressure. After the outbreak of the Second World War in September 1939, Eichmann and his staff arranged for Jews to be concentrated in ghettos in major cities with the expectation that they would be transported either farther east or overseas. He also drew up plans for a Jewish reservation, first at Nisko in southeast Poland and later in Madagascar, but neither of these plans were carried out.

Hinrich Lohse (2 September 1896 – 25 February 1964) was a German Nazi Party official, politician and convicted war criminal. He served as the Gauleiter and Oberpräsident of Schleswig-Holstein and was an SA-Obergruppenführer in the Nazi paramilitary organization, the Sturmabteilung (SA). He is best known for his rule of the Reichskommissariat Ostland, during the Second World War. The Reichskommissariat comprised the modern-day states of Lithuania, Latvia, and Estonia, as well as parts of Belarus, and was the scene of Holocaust-related atrocities. Lohse was sentenced to ten years in prison in 1948 but was released in 1951.

Babi Yar (Russian: Бабий Яр) or Babyn Yar (Ukrainian: Бабин Яр) is a ravine in the Ukrainian capital Kyiv and a site of massacres carried out by Nazi Germany's forces during its campaign against the Soviet Union in World War II. The first and best documented of the massacres took place on 29–30 September 1941, in which some 33,771 Jews were murdered. Other victims of massacres at the site included Soviet prisoners of war, communists and Romanies. It is estimated that a total of between 100,000 and 150,000 people were murdered at Babi Yar during the German occupation.

The decision to murder all the Jews in Kiev was made by the German military governor Generalmajor Kurt Eberhard, the Police Commander for Army Group South, SS-Obergruppenführer Friedrich Jeckeln, and the Einsatzgruppe C Commander Otto Rasch. Sonderkommando 4a as the sub-unit of Einsatzgruppe C, along with the aid of the SD and Order Police battalions with the Ukrainian Auxiliary Police backed by the Wehrmacht, carried out the orders. Sonderkommando 4a and the 45th Battalion of the German Order Police conducted the shootings. Servicemen of the 303rd Battalion of the German Order Police at this time guarded the outer perimeter of the execution site.

Jozef Gabčík (Slovak pronunciation: [ˈjɔzev ˈɡaptʂiːk]; 8 April 1912 – 18 June 1942) was a Slovak soldier in the Czechoslovak Army involved in the Operation Anthropoid, the assassination of acting Reichsprotektor (Realm-Protector) of the Protectorate of Bohemia and Moravia, SS-Obergruppenführer Reinhard Heydrich.
