The Sturmabteilung, literally "Storm Detachment", was the Nazi Party's original paramilitary wing. It played a significant role in Adolf Hitler's rise to power in the 1920s and 1930s. Its primary purposes were providing protection for Nazi rallies and assemblies; disrupting the meetings of opposing parties; fighting against the paramilitary units of the opposing parties, especially the Roter Frontkämpferbund of the Communist Party of Germany (KPD) and the Reichsbanner Schwarz-Rot-Gold of the Social Democratic Party of Germany (SPD); and intimidating Romani, trade unionists, and especially Jews such as during the 1933 Nazi boycott of Jewish businesses.

The Night of the Long Knives, or the Röhm Purge, also called Operation Hummingbird, was a purge that took place in Nazi Germany from June 30 to July 2, 1934. Chancellor Adolf Hitler, urged on by Hermann Göring and Heinrich Himmler, ordered a series of political extrajudicial executions intended to consolidate his power and alleviate the concerns of the German military about the role of Ernst Röhm and the Sturmabteilung (SA), the Nazis' paramilitary organization. Nazi propaganda presented the murders as a preventive measure against an alleged imminent coup by the SA under Röhm – the so-called Röhm Putsch.

People killed during the Night of the Long Knives – the Nazi purge in which Hitler and the Nazi regime used the Schutzstaffel (SS) to deal with the problem of Ernst Röhm and his Sturmabteilung (SA) brownshirts, as well as past opponents of the party – numbered at least 85 people murdered. It took place in Germany between June 30 and July 2, 1934.

This article lists the commanders of the Sturmabteilung, a paramilitary wing of the Nazi Party (NSDAP), between the years of 1920 and 1945.

Stabschef was an office and paramilitary rank in the Sturmabteilung (SA), the paramilitary stormtroopers associated with the Nazi Party. It was a rank and position held by the operating chief of the SA. The rank is equivalent to the rank of Generaloberst in the German Army and to General in the US Army.

The Stennes Revolt was a revolt within the Nazi Party in 1930-1931 led by Walter Stennes (1895–1983), the Berlin commandant of the Sturmabteilung (SA), the Nazi's "brownshirt" storm troops. The revolt arose from internal tensions and conflicts within the Nazi Party of Germany, particularly between the party organization headquartered in Munich and Adolf Hitler on the one hand, and the SA and its leadership on the other hand. There is some evidence that Stennes may have been paid by the government of German chancellor Heinrich Brüning, with the intention of causing conflict within the Nazi movement.

The uniforms and insignia of the Sturmabteilung (SA) were Nazi Party paramilitary ranks and uniforms used by SA stormtroopers from 1921 until the fall of Nazi Germany in 1945. The titles and phrases used by the SA were the basis for paramilitary titles used by several other Nazi paramilitary groups, among them the Schutzstaffel (SS). Early SS ranks were identical to the SA, since the SS was originally considered a sub-organization of the Sturmabteilung.
