Editing Duke (section)

== Duchy and dukedom ==
{{main|Duchy}}
A duchy is the territory or geopolitical entity ruled by a duke, whereas his title or area is often called a dukedom. The [[Grand Duchy of Luxembourg]] is a fully independent state and its head, the Grand Duke, is a sovereign monarch reigning over his Luxembourgish subjects.

The [[Duke of Cornwall]] holds both the dukedom (title) and duchy (estate holdings), the latter being the source of his personal income; those living on the ducal estates are subjects of the British sovereign and owe neither fealty nor services to the duke ''per se''.{{citation needed|date=December 2016}} In Scotland, the male heir apparent to the British crown is always the [[Duke of Rothesay]] as well, but this is a dukedom (title) without a duchy. Similarly, the British monarch rules and owns the [[Duchy of Lancaster]] as [[Duke of Lancaster]], but it is held separately from the Crown, with the income of the duchy estates providing the sovereign's [[Privy Purse]].

The Channel Islands are two of the three remaining [[Crown Dependencies]], the last vestiges of the lands of the Duchy of Normandy. The Islanders in their loyal toast will say "Le Roi, notre Duc" (The King, Our Duke). Though the title was apparently renounced under the [[Treaty of Paris (1259)|Treaty of Paris]] in 1259, the Crown still maintains that the title is retained: "In 1106, William's youngest son Henry I seized the Duchy of Normandy from his brother Robert; since that time, the English sovereign has always held the title [[Duke of Normandy]]", and that "By 1205, England had lost most of its French lands, including Normandy. However, the Channel Islands, part of the lost Duchy, remained a self-governing possession of the English Crown. While the islands today retain autonomy in government, they owe allegiance to The King in his role as Duke of Normandy."<ref>{{cite web|url=http://www.royal.gov.uk/MonarchUK/QueenandCrowndependencies/ChannelIslands.aspx|title=Channel Islands|date=2009|website=The Official Website of the British Monarchy|publisher=The Royal Household|access-date=16 August 2013|url-status=dead|archive-url=https://web.archive.org/web/20120921052748/http://www.royal.gov.uk/MonarchUK/QueenandCrowndependencies/ChannelIslands.aspx|archive-date=21 September 2012}}</ref>
