The rank existed in the Austrian Empire as Kaiserlicher Feldmarschall ("imperial field marshal") and in the Austro-Hungarian Empire as Kaiserlicher und königlicher Feldmarschall ("imperial and royal field marshal"). Both were based on usage in the Holy Roman Empire. The monarch held the rank ex officio, other officers were promoted as required. Between 1914 and 1918, ten men attained this rank, of whom four were members of the reigning Habsburg dynasty.
In the German-Prussian Army and later in the Wehrmacht, the rank of Generalfeldmarschall had several privileges, such as elevation to nobility, equal protocol rank with cabinet ministers, the right of reporting directly to the monarch, and a constant escort.
In 1854, the rank of colonel-general (German: Generaloberst) was created in order to promote William, Prince of Prussia (the later William I, German Emperor) to senior rank without breaking the rule that only wartime field commanders could receive the rank of field marshal for a victory in a decisive battle or the capture of a fortification or major town. The equivalent of colonel-general in the German Navy was the rank of Generaladmiral ("general admiral" or "admiral-general").
The exalted nature of the rank was underscored during World War I, when only five German officers (excluding honorary promotions to members of royal families and foreign officers) were designated Generalfeldmarschall: Paul von Hindenburg, August von Mackensen, Karl von Bülow, Hermann von Eichhorn, and Remus von Woyrsch. Only a single naval officer, Henning von Holtzendorff, was designated Grand Admiral. Not even such well-known German commanders as Erich Ludendorff, Erich von Falkenhayn, or Reinhard Scheer received marshal's batons or Grand Admiral rank.
Before World War II Hitler promoted War Minister Werner von Blomberg (20 April 1936) and Aviation Minister Hermann Göring (4 February 1938) to the rank of Generalfeldmarschall. In the Wehrmacht of Nazi Germany during World War II, the rank of Generalfeldmarschall remained the highest military rank until July 1940, when Hermann Göring was promoted to the newly created higher rank of Reichsmarschall. The equivalent of a Generalfeldmarschall in the navy was Großadmiral ("grand admiral").
Unlike Kaiser Wilhelm II, Adolf Hitler distributed the rank more widely, promoting 25 Heer and Luftwaffe officers in total and two Kriegsmarine Grand Admirals. (Another promotion, that of Austrian General Eduard von Böhm-Ermolli, was honorary.) Four weeks after the Heer and Luftwaffe had won the Battle of France, a Blitzkrieg in the Low Countries and France (10 May – 22 June 1940), Hitler promoted twelve generals to the rank of field marshal. Those promoted on 19 July 1940, were Walther von Brauchitsch, Wilhelm Keitel, Gerd von Rundstedt, Fedor von Bock, Wilhelm von Leeb, Wilhelm List, Günther von Kluge, Erwin von Witzleben, Walter von Reichenau (Heer) and Albert Kesselring, Erhard Milch, Hugo Sperrle (Luftwaffe).
