Nazi Party Office of Racial Policy

The Schutzstaffel (SS; also stylized as ᛋᛋ with Armanen runes; German pronunciation: [ˈʃʊtsˌʃtafl̩] (listen); "Protection Squadron") was a major paramilitary organization under Adolf Hitler and the Nazi Party in Nazi Germany, and later throughout German-occupied Europe during World War II. It began with a small guard unit known as the Saal-Schutz ("Hall Security") made up of party volunteers to provide security for party meetings in Munich. In 1925, Heinrich Himmler joined the unit, which had by then been reformed and given its final name. Under his direction (1929–1945) it grew from a small paramilitary formation during the Weimar Republic to one of the most powerful organizations in Nazi Germany. From the time of the Nazi Party's rise to power until the regime's collapse in 1945, the SS was the foremost agency of security, surveillance, and terror within Germany and German-occupied Europe. The two main constituent groups were the Allgemeine SS (General SS) and Waffen-SS (Armed SS). The Allgemeine SS was responsible for enforcing the racial policy of Nazi Germany and general policing, whereas the Waffen-SS consisted of combat units within Nazi Germany's military. A third component of the SS, the SS-Totenkopfverbände (SS-TV; "Death's Head Units"), ran the concentration camps and extermination camps. Additional subdivisions of the SS included the Gestapo and the Sicherheitsdienst (SD) organizations. They were tasked with the detection of actual or potential enemies of the Nazi state, the neutralization of any opposition, policing the German people for their commitment to Nazi ideology, and providing domestic and foreign intelligence. The SS was the organization most responsible for the genocidal murder of an estimated 5.5 to 6 million Jews and millions of other victims during the Holocaust. Members of all of its branches committed war crimes and crimes against humanity during World War II (1939–45). The SS was also involved in commercial enterprises and exploited concentration camp inmates as slave labor. After Nazi Germany's defeat, the SS and the Nazi Party were judged by the International Military Tribunal at Nuremberg to be criminal organizations. Ernst Kaltenbrunner, the highest-ranking surviving SS main department chief, was found guilty of crimes against humanity at the Nuremberg trials and hanged in 1946.

Niederkirchnerstraße (German: [ˈniːdɐkɪʁçnɐˌʃtʁaːsə]) is a street in Berlin, Germany and was named after Käthe Niederkirchner. The thoroughfare was known as Prinz-Albrecht-Straße until 1951 but the name was changed by the socialist German government. The street was the location of the SS Reich Security Main Office (RSHA), the headquarters of the Sicherheitspolizei, SD, Einsatzgruppen and Gestapo. The site is now marked by the Topography of Terror memorial and a museum, which includes a permanent exhibition showing the crimes of Nazism.

The Topography of Terror (German: Topographie des Terrors) is an outdoor and indoor history museum in Berlin, Germany. It is located on Niederkirchnerstrasse, formerly Prinz-Albrecht-Strasse, on the site of buildings, which during the Nazi regime from 1933 to 1945 was the SS Reich Security Main Office, the headquarters of the Sicherheitspolizei, SD, Einsatzgruppen and Gestapo. The buildings that housed the Gestapo and SS headquarters were largely destroyed by Allied bombing during early 1945 and the ruins demolished after the war. The boundary between the American and Soviet zones of occupation in Berlin ran along the Prinz-Albrecht-Strasse, so the street soon became a fortified boundary, and the Berlin Wall ran along the south side of the street, renamed Niederkirchnerstrasse, from 1961 to 1989. The wall here was never demolished. The section adjacent to the Topography of Terror site is the longest extant segment of the outer wall, as the longer East Side Gallery section in Friedrichshain was part of the inner wall, not visible from West Berlin. The first exhibitions of the site took place in 1987, as part of Berlin's 750th anniversary. The cellar of the Gestapo headquarters, where many political prisoners were tortured and executed, was found and excavated. The site was then turned into a memorial and museum, in the open air but protected from the elements by a canopy, detailing the history of repression under the Nazis. The excavation took place in cooperation with East German researchers, and a joint exhibition was shown both at the site and in East Germany in 1989. In 1992, two years after German reunification, a foundation was established to take care of the site, and the following year, it initiated an architectural competition to design a permanent museum. A design by architect Peter Zumthor was chosen. However, construction was stopped due to funding problems after the concrete core of the structure had been built. This stood on the site for nearly a decade until it was finally demolished in 2004 and a new building begun. The construction of the new Documentation Centre according to a prize-winning design by the architect Ursula Wilms (Heinle, Wischer und Partner, Berlin) and the landscape architect Heinz W. Hallmann (Aachen) was finished in 2010. The new Documentation Centre was officially opened on 6 May 2010 by Federal President Horst Köhler on the occasion of the 65th anniversary of the end of World War II. The new exhibition and documentation building and the redesigned historic grounds were opened to the public on 7 May 2010.

Martin-Gropius-Bau, commonly known as Gropius Bau, is an important exhibition building in Berlin, Germany. Originally a museum of applied arts, the building has been a listed historical monument since 1966. It is located at 7 Niederkirchnerstraße in Berlin-Kreuzberg,

The Abgeordnetenhaus of Berlin (House of Deputies) (German: [ˈʔapɡəʔɔʁdnətn̩ˌhaʊs]) is the state parliament (Landtag) of Berlin, Germany according to the city-state's constitution. In 1993 the parliament moved from Rathaus Schöneberg to its present house on Niederkirchnerstraße in Mitte, which until 1934 was the seat of the Prussian Landtag. The current president of the parliament is Dennis Buchner (SPD).

The Landtag of Prussia (German: Preußischer Landtag) was the representative assembly of the Kingdom of Prussia implemented in 1849, a bicameral legislature consisting of the upper House of Lords (Herrenhaus) and the lower House of Representatives (Abgeordnetenhaus). After World War I and the German Revolution of 1918–19 the Landtag diet continued as the parliament of the Free State of Prussia between 1921 and 1934, when it was abolished by the Nazi regime.

The Ministry of Aviation (German: Reichsluftfahrtministerium, abbreviated RLM) was a government department during the period of Nazi Germany (1933–45). It is also the original name of the Detlev-Rohwedder-Haus building on the Wilhelmstrasse in central Berlin, Germany, which today houses the German Finance Ministry (German: Bundesministerium der Finanzen). The Ministry was in charge of development and production of all aircraft developed, designed and built in Germany during the existence of the Third Reich, overseeing all matters concerning both military and civilian designs – it handled military aviation matters as its top priority, particularly for the Luftwaffe. As was characteristic of government departments in the Nazi era, the Ministry was personality-driven and formal procedures were often ignored in favour of the whims of the Minister, Reichsmarschall Hermann Göring. As a result, early successes in aircraft development progressed only slowly and erratically during World War II.

The Detlev-Rohwedder-Haus (Detlev Rohwedder House) is a building in Berlin that, at the time of its construction, was the largest office building in Europe. It was constructed between February 1935 and August 1936 to house the German Ministry of Aviation (German: Reichsluftfahrtministerium - RLM), headed by Hermann Göring, a leading Nazi. During the German Democratic Republic (East Germany) it was known as the Haus der Ministerien ("House of Ministries"). In 1992, it was named the Detlev Rohwedder Building, in honour of Detlev Karsten Rohwedder, the former President of the Treuhand, which had its headquarters there 1991–1995, who was assassinated by far-left terrorist group Red Army Faction in 1991. Since 1999, the building has been the seat of the German Finance Ministry.

The Federal Ministry of Finance (German: Bundesministerium der Finanzen), abbreviated BMF, is the cabinet-level finance ministry of Germany, with its seat at the Detlev-Rohwedder-Haus in Berlin and a secondary office in Bonn. The current Federal Minister of Finance is Christian Lindner (FDP).

The German Bundesrat (lit. Federal Council; pronounced [ˈbʊndəsʁaːt]) is a legislative body that represents the sixteen Länder (federated states) of Germany at the federal level (German: Bundesebene). The Bundesrat meets at the former Prussian House of Lords in Berlin. Its second seat is located in the former West German capital of Bonn. The Bundesrat participates in legislation, alongside the Bundestag consisting of directly elected representatives of the German people. Laws that affect state powers, and all constitutional changes, need the consent of both houses. For its somewhat similar function, the Bundesrat is sometimes (controversially) described as an upper house of parliament along the lines of the United States Senate, the Canadian Senate, and the British House of Lords.Bundesrat was the name of similar bodies in the North German Confederation (1867) and the German Empire (1871). Its predecessor in the Weimar Republic (1919–1933) was the Reichsrat. The political makeup of the Bundesrat is affected by changes in power in the states of Germany, and thus by elections in each state. Each state delegation in the Bundesrat is essentially a representation of the state government and reflects the political makeup of the ruling majority or plurality of each state legislature (including coalitions). Thus the Bundesrat is a continuous body and has no legislative periods. For organizational reasons, the Bundesrat structures its legislative calendar in years of business (Geschäftsjahre), beginning each year on 1 November. Each year of business is congruous with the one-year-term of the presidium. The sessions have been counted continuously since the first session on 7 September 1949. The Bundesrat's 1000th session, which was opened by a speech held by President of Germany Frank-Walter Steinmeier, took place on 12 February 2021.

The Präsidium of the Bundesrat in Germany is responsible for various functions, including the Bundesrat's budget allocation and other internal matters. The current President of the Bundesrat is Reiner Haseloff, the Minister President of Saxony Anhalt, whose one-year term started on 1 November 2020. The President convenes and chairs plenary sessions of the body and is formally responsible for representing the Bundesrat of Germany. He or she is aided by two vice-presidents who play an advisory role and deputise in the president's absence. The three constitute the Präsidium of the Bundesrat.If the office of Federal President of Germany is vacant, the President of the Bundesrat serves as acting Federal President.

The Prussian House of Lords (German: Preußisches Herrenhaus) in Berlin was the upper house of the Landtag of Prussia (German: Preußischer Landtag), the parliament of Prussia from 1850 to 1918. Together with the lower house, the House of Representatives (Abgeordnetenhaus), it formed the Prussian bicameral legislature. The building is now used as the seat of the German Bundesrat.
