Editing Duke (section)

==== Denmark ====
Beginning in the 11th century, Danish kings frequently awarded the title of ''jarl'' (earl) or duke of [[Duchy of Schleswig|Schleswig]] to a younger son of the monarch. Short-lived dukedoms were created for the same purpose in [[Lolland]] and [[Halland]].

After the accession to the throne of [[Christian I of Denmark|Christian I]], a complex system of appanages were created for male-line descendants of the king, being granted non-sovereign ducal titles in both Schleswig and [[Duchy of Holstein|Holstein]], e.g. [[Duke of Gottorp]], Duke of Sønderborg, [[Duke of Augustenborg]], Duke of Franzhagen, Duke of Beck, [[Duke of Glücksburg]] and Duke of Nordborg. This arrangement occurred in both territories despite Schleswig being a fief of Denmark and Holstein being a fief of the [[Holy Roman Empire]].
