Edler (German: [ˈeːdlɐ]) was until 1919 the lowest rank of nobility in Austria-Hungary and Germany, just beneath a Ritter (hereditary knight), but above untitled nobles, who used only the nobiliary particle von before their surname. It was mostly given to civil servants and military officers, as well as those upon whom the lower rank of an Order had been conferred. The noun Edler comes from the adjective edel ("noble"), and translated literally means "noble [person]". In accordance with the rules of German grammar, the word can also appear as Edle, Edlem, or Edlen depending on case, gender, and number.
Originally, from the Middle Ages, under the feudal system (in Europe and elsewhere), the nobility were generally those who held a fief, often in the form of heritable land worked by vassals. To preserve the feudal naming practice, even in cases where upper-ranking bureaucrats received patents of nobility for long service or merit, as in the 18th, 19th, and early 20th centuries (see noblesse de robe), the old practice of denoting a noble with a territorial designation was continued out of a sense of tradition.
