The Schutzstaffel (German: [ˈʃʊtsˌʃtafl̩] ; lit. 'Protection Squadron'; SS; also stylised with SS runes as ᛋᛋ) was a major paramilitary organisation 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 organisations 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, mass surveillance, and state terrorism 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 the combat units of the SS, with a sworn allegiance to Hitler. 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) organisations. They were tasked with detecting actual or potential enemies of Nazi Germany, neutralizing the opposition, policing the German people for their commitment to Nazi ideology and providing domestic and foreign intelligence.
The SS was the organisation most responsible for the genocidal murder of an estimated 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 (1939–1945). The SS was also involved in commercial enterprises and exploited concentration camp inmates as slave labour. After Nazi Germany's defeat, the SS and the Nazi Party were judged by the International Military Tribunal at Nuremberg to be criminal organisations. 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.
By 1923, the Nazi Party led by Adolf Hitler had created a small volunteer guard unit known as the Saal-Schutz (Hall Security) to provide security at their meetings in Munich. The same year, Hitler ordered the formation of a small bodyguard unit dedicated to his personal service. He wished it to be separate from the "suspect mass" of the party, including the paramilitary Sturmabteilung ("Storm Battalion"; SA), which he did not trust. The new formation was designated the Stabswache (Staff Guard). Originally the unit was composed of eight men, commanded by Julius Schreck and Joseph Berchtold, and was modelled after the Erhardt Naval Brigade, a Freikorps of the time. The unit was renamed Stoßtrupp (Shock Troops) in May 1923.
The Stoßtrupp was abolished after the failed 1923 Beer Hall Putsch, an attempt by the Nazi Party to seize power in Munich. In 1925, Hitler ordered Schreck to organise a new bodyguard unit, the Schutzkommando (Protection Command). It was tasked with providing personal protection for Hitler at party functions and events. That same year, the Schutzkommando was expanded to a national organisation and renamed successively the Sturmstaffel (Storm Squadron), and finally the Schutzstaffel (Protection Squad; SS). Officially, the SS marked its foundation on 9 November 1925 (the second anniversary of the Beer Hall Putsch). The new SS protected party leaders throughout Germany. Hitler's personal SS protection unit was later enlarged to include combat units.
Schreck, a founding member of the SA and a close confidant of Hitler, became the first SS chief in March 1925. On 15 April 1926, Joseph Berchtold succeeded him as chief of the SS. Berchtold changed the title of the office to Reichsführer-SS (Reich Leader-SS). Berchtold was considered more dynamic than his predecessor but became increasingly frustrated by the authority the SA had over the SS. This led to him transferring leadership of the SS to his deputy, Erhard Heiden, on 1 March 1927. Under Heiden's leadership, a stricter code of discipline was enforced than would have been tolerated in the SA.
Between 1925 and 1929, the SS was considered to be a small Gruppe (battalion) of the SA. Except in the Munich area, the SS was unable to maintain any momentum in its membership numbers, which declined from 1,000 to 280 as the SA continued its rapid growth. As Heiden attempted to keep the SS from dissolving, Heinrich Himmler became his deputy in September 1927. Himmler displayed better organisational abilities than Heiden. The SS established a number of Gaue (regions or provinces). The SS-Gaue consisted of SS-Gau Berlin, SS-Gau Berlin Brandenburg, SS-Gau Franken, SS-Gau Niederbayern, SS-Gau Rheinland-Süd, and SS-Gau Sachsen.
With Hitler's approval, Himmler assumed the position of Reichsführer-SS in January 1929. There are differing accounts of the reason for Heiden's dismissal from his position as head of the SS. The party announced that it was for "family reasons". Under Himmler, the SS expanded and gained a larger foothold. He considered the SS an elite, ideologically driven National Socialist organisation, a "conflation of Teutonic knights, the Jesuits, and Japanese Samurai". His ultimate aim was to turn the SS into the most powerful organisation in Germany and the most influential branch of the party. He expanded the SS to 3,000 members in his first year as its leader.
In 1929, the SS-Hauptamt (main SS office) was expanded and reorganised into five main offices dealing with general administration, personnel, finance, security, and race matters. At the same time, the SS-Gaue were divided into three SS-Oberführerbereiche areas, namely the SS-Oberführerbereich Ost, SS-Oberführerbereich West, and SS-Oberführerbereich Süd. The lower levels of the SS remained largely unchanged. Although officially still considered a sub-organisation of the SA and answerable to the Stabschef (SA Chief of Staff), it was also during this time that Himmler began to establish the independence of the SS from the SA. The SS grew in size and power due to its exclusive loyalty to Hitler, as opposed to the SA, which was seen as semi-independent and a threat to Hitler's hegemony over the party, mainly because they demanded a "second revolution" beyond the one that brought the Nazi Party to power. By the end of 1933, the membership of the SS reached 209,000. Under Himmler's leadership, the SS continued to gather greater power as more and more state and party functions were assigned to its jurisdiction. Over time the SS became answerable only to Hitler, a development typical of the organisational structure of the entire Nazi regime, where legal norms were replaced by actions undertaken under the Führerprinzip (leader principle), where Hitler's will was considered to be above the law.
In the latter half of 1934, Himmler oversaw the creation of SS-Junkerschule, institutions where SS officer candidates received leadership training, political and ideological indoctrination, and military instruction. The training stressed ruthlessness and toughness as part of the SS value system, which helped foster a sense of superiority among the men and taught them self-confidence. The first schools were established at Bad Tölz and Braunschweig, with additional schools opening at Klagenfurt and Prague during the war.
The SS was regarded as the Nazi Party's elite unit. In keeping with the racial policy of Nazi Germany, in the early days all SS officer candidates had to provide proof of Aryan ancestry back to 1750 and for other ranks to 1800. Once the war started and it became more difficult to confirm ancestry, the regulation was amended to proving only the candidate's grandparents were Aryan, as spelled out in the Nuremberg Laws. Other requirements were complete obedience to the Führer and a commitment to the German people and nation. Himmler also tried to institute physical criteria based on appearance and height, but these requirements were only loosely enforced, and over half the SS men did not meet the criteria. Inducements such as higher salaries and larger homes were provided to members of the SS since they were expected to produce more children than the average German family as part of their commitment to Nazi Party doctrine.
