Junker (German: Junker, Dutch: Jonkheer, Scandinavian: Junker) is a noble honorific, derived from Middle High German Juncherre, meaning "young nobleman" or otherwise "young lord" (derivation of jung and Herr). The term is traditionally used throughout the German-speaking, Dutch-speaking and Scandinavian-speaking parts of Europe.
In Brandenburg Junker was originally the members of the higher edelfrei (immediate) nobility without or before the accolade. It evolved to a general denotation of a young or lesser noble, sometimes poor and politically insignificant, understood as "country squire".
As part of the nobility, many Junker families only had prepositions such as von or zu before their family names without further ranks. The abbreviation of Junker was Jkr., most often placed before the given name and titles, for example: Jkr. Heinrich von Hohenberg. The female equivalent Junkfrau (Jkfr.) was used only sporadically. In some cases, the honorific Jkr. was also used for Freiherren (Barons) and Grafen (Counts).
Junker (or its Dutch cognate Jonkheer) was traditionally used as a noble honorific throughout the German-speaking and Dutch-speaking part of Europe. The title today survives in its traditional meaning in the Netherlands and Belgium in the Dutch form Jonkheer.
The term was also used in several countries in the title Kammerjunker, the German and Scandinavian (Danish, Norwegian and Swedish) equivalent of the French valet de chambre, a position usually given to young noble men in the service of a princely rank person at the court. A Kammerjunker was ranked below a chamberlain, but above a chamber page. Furthermore, the title has been used in military titles in the German and Scandinavian realm, such as Fahnenjunker and its Scandinavian equivalent fanejunker.
In Denmark, the term Junker connotes a young lord, originally the son of a duke or count in the Middle Ages, but also a term for a member of the privileged landowner class. Before 1375 the honorific was also suitable for Danish royal sons. It was also used in the title Kammerjunker within the royal household.
Modern popular usage in Prussia
In modern Prussian history, the term Junker became popularly used as a loosely defined synecdoche for the landed nobility (particularly of the east) that controlled almost all of the land and government, or by extension, the Prussian estate owners regardless of noble status. With the formation of the German Empire in 1871, the Junkers dominated the central German government and the Prussian military. A leading representative was Prince Otto von Bismarck. "The Junkers" of Prussia were often contrasted with the elites of the western and southern states in Germany, such as the city-republic of Hamburg (which had no nobility) or Catholic states like Bavaria, in which the "Junker class" of Prussia was often treated with contempt.
