Hermann Göring in the context of "German nuclear program during World War II"

The Blitz (English: 'flash') was a bombing campaign by Nazi Germany and Fascist Italy against the United Kingdom during the Second World War. It lasted for eight months, from 7 September, 1940 to 11 May, 1941. The name is a shortened form of Blitzkrieg, a term used in the popular press to describe a German style of surprise attack used during the war.

Towards the end of the Battle of Britain in 1940, daylight air superiority over the United Kingdom was contested between the Luftwaffe and the Royal Air Force. Germany began conducting mass air attacks against British cities, beginning with London, in an attempt to draw the RAF Fighter Command into a battle of annihilation. Adolf Hitler and Reichsmarschall Hermann Göring, commander-in-chief of the Luftwaffe, ordered the new policy on 6 September 1940. From 7 September 1940, London was systematically bombed by the Luftwaffe for 56 of the following 57 days and nights. The attacks included a large daylight attack against London on 15 September, a large raid on 29 December 1940 against London resulting in a firestorm known as the Second Great Fire of London, and a large raid on the night of 10–11 May 1941.

The Luftwaffe (German pronunciation: [ˈlʊftvafə] ) was the aerial-warfare branch of the Wehrmacht before and during World War II. Germany's military air arms during World War I, the Luftstreitkräfte of the Imperial Army and the Marine-Fliegerabteilung of the Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles, which banned Germany from having any air force.

During the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk Air Base in the Soviet Union. With the rise of the Nazi Party and the repudiation of the Versailles Treaty, the Luftwaffe's existence was publicly acknowledged and officially established on 26 February 1935, just over two weeks before open defiance of the Versailles Treaty through German rearmament and conscription would be announced on 16 March. The Condor Legion, a Luftwaffe detachment sent to aid Nationalist forces in the Spanish Civil War, provided the force with a valuable testing ground for new tactics and aircraft. Partially as a result of this combat experience, the Luftwaffe had become one of the most sophisticated, technologically advanced, and battle-experienced air forces in the world when World War II began on 1 September 1939. By the summer of 1939, the Luftwaffe had twenty-eight Geschwader (wings). The Luftwaffe also operated a paratrooper force known as the Fallschirmjäger.

Reichsmarschall (German: Reichsmarschall des Großdeutschen Reiches; lit. 'Reich Marshal of the Greater German Reich') was an honorary military rank, specially created for Hermann Göring during World War II, and the de jure highest rank in the Wehrmacht. It was senior to the rank of Generalfeldmarschall (lit. 'general field marshal', equivalent to field marshal, which was previously the highest rank in the Wehrmacht), but was merely a ceremonial appointment to accentuate Göring's position as Hitler's designated successor. No actual subordination of the other field marshals or a superior position of the holder followed from it. It was equivalent to General of the Armies in the United States, or Generalissimo in other countries.

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).

Max Jakob Friedländer (5 July 1867 in Berlin – 11 October 1958 in Amsterdam) was a German-Jewish museum curator and art historian. He was a specialist in Early Netherlandish painting and the Northern Renaissance, who volunteered at the Kupferstichkabinett Berlin in 1891 under Friedrich Lippmann. On Lippmann's recommendation, Wilhelm von Bode took him on as his assistant in 1896 for the paintings division. He was appointed deputy director of the Kaiser Friedrich Museum (then containing the Berlin State Museums' old master paintings and sculpture) under Bode in 1904 and became director himself from 1924 to 1932, working on his history From Van Eyck to Bruegel and the 14-volume (printed in 16, with supplements) survey Early Netherlandish Painting. In 1933 he was dismissed as a "non-Aryan" and in 1939 had to move to Amsterdam because he was Jewish. He attained the rank and title of geheimrat (privy councillor) under the German Empire. He also donated several works to the collection and worked in the art trade as an advisor, to Hermann Göring among others.

He invented the style term Antwerp Mannerism, and created many of the notnames for undocumented artists in this style, and others of the period.

Nazi Germany undertook several research programs relating to nuclear technology, including nuclear weapons and nuclear reactors, before and during World War II. These were variously called Uranverein (Uranium Society) or Uranprojekt (Uranium Project). The first effort started in April 1939, just months after the discovery of nuclear fission in Berlin in December 1938, but ended shortly ahead of the September 1939 German invasion of Poland, for which many German physicists were drafted into the Wehrmacht. A second effort under the administrative purview of the Wehrmacht's Heereswaffenamt began on September 1, 1939, the day of the invasion of Poland. The program eventually expanded into three main efforts: Uranmaschine (nuclear reactor) development, uranium and heavy water production, and uranium isotope separation. Eventually, the German military determined that nuclear fission would not contribute significantly to the war, and in January 1942 the Heereswaffenamt turned the program over to the Reich Research Council (Reichsforschungsrat) while continuing to fund the activity.

The program was split up among nine major institutes where the directors dominated research and set their own objectives. Subsequently, the number of scientists working on applied nuclear fission began to diminish as many researchers applied their talents to more pressing wartime demands. The most influential people in the Uranverein included Kurt Diebner, Abraham Esau, Walther Gerlach, and Erich Schumann. Schumann was one of the most powerful and influential physicists in Germany. Diebner, throughout the life of the nuclear weapon project, had more control over nuclear fission research than did Walther Bothe, Klaus Clusius, Otto Hahn, Paul Harteck, or Werner Heisenberg. Esau was appointed as Reichsmarschall Hermann Göring's plenipotentiary for nuclear physics research in December 1942, and was succeeded by Walther Gerlach after he resigned in December 1943.

Erhard Milch (30 March 1892 – 25 January 1972) was a German Generalfeldmarschall of the Luftwaffe who oversaw its founding and development during the rearmament of Germany and most of World War II. Milch served as State Secretary in the Reich Ministry of Aviation from May 1933 to June 1944 and as Inspector General of the Luftwaffe from February 1939 to January 1945.

Milch was an early member of the Luftstreitkräfte during World War I and worked as an airline director in the German civil aviation industry after the war. Milch was appointed deputy of Hermann Göring in the Aviation Ministry in 1933, heading the organisation and development of the Luftwaffe from 1936. Milch led Nazi Germany's aircraft production and supply from 1941, adopting a policy of mass production, and utilising the forced labour of foreign workers under inhumane conditions to supply the Luftwaffe. Milch was removed from his important Aviation Ministry positions after supporting a failed attempt to remove Göring in June 1944 and sidelined until his capture by Allied forces in May 1945.

The Night of the Long Knives (German: Nacht der langen Messer [ˈnaxt dɛɐ̯ ˈlaŋən ˈmɛsɐ] ), also called the Röhm purge or Operation Hummingbird (German: Aktion Kolibri), was a purge that took place in Nazi Germany from 30 June to 2 July 1934. Chancellor Adolf Hitler, urged on by Hermann Göring and Heinrich Himmler, ordered a series of extrajudicial executions intended to consolidate his power and alleviate the German military's concerns about the role of Ernst Röhm and the Sturmabteilung (SA), the Nazis' paramilitary organization, known colloquially as "Brownshirts". Nazi propaganda presented the murders as a preventive measure against an alleged imminent coup by the SA under Röhm—the so-called Röhm Putsch.

The primary instruments of Hitler's action were the Schutzstaffel (SS) paramilitary force under Himmler and its Security Service (SD), and the Gestapo (secret police) under Reinhard Heydrich, which between them carried out most of the killings. Göring's personal police battalion also took part. Many of those killed in the purge were leaders of the SA, the best-known being Röhm himself, the SA's chief of staff and one of Hitler's longtime supporters and allies. Leading members of the Strasserist faction of the Nazi Party, including its leader Gregor Strasser, were also killed, as were establishment conservatives and anti-Nazis, such as former Chancellor Kurt von Schleicher and Bavarian politician Gustav Ritter von Kahr, who had helped suppress Hitler's Beer Hall Putsch in 1923. The murders of SA leaders were also intended to improve the image of the Hitler government with a German public increasingly critical of thuggish SA tactics.

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.
