About duchy names

A duchy is the territory ruled by a duke or duchess, ranking below a kingdom and above a county or barony. Historically almost every duchy took its name from a place, a people, or a river rather than from its ruling family: Burgundy from the Burgundians, Saxony from the Saxons, Brabant from an old Frankish district, Normandy from the Norse settlers of northern France. When dynastic branches split their lands, hyphenated forms appeared, which is why we have Saxe-Coburg, Saxe-Weimar and Mecklenburg-Schwerin. Lancaster and Cornwall survive today as royal estates.

A convincing invented duchy therefore needs a place-name that fits the language of your setting. English-flavoured duchies use endings such as -moor, -mere, -holt, -wick, -combe and -dale (Aldenmoor, Elstermere, Lorwyck); Germanic ones use -mark, -berg, -holm and -stein (Ostmark, Kaltenberg, Wystenholm); French ones favour -mont, -court and -vaine (Bellamont, Valcourt, Trevaine). Descriptive names such as Duchy of the Westmarch or Duchy of the Silver Coast suit frontier or coastal territories.

The names below combine real historical duchies and British dukedoms for reference with original names in English, German, French, Norse and Celtic registers, high-fantasy coinages, descriptive regional forms, native titles such as Herzogtum and Duché, and a few Grand Duchies and Archduchies. Use them for a Crusader Kings dynasty, a fantasy map, or a noble house in your novel.

How to choose duchy names

  • Pick the linguistic register that matches the rest of your map; a Duchy of Kaltenberg next to a Duchy of Beaumarais implies two different cultures, which is fine if intended.
  • Reserve Grand Duchy and Archduchy for realms that hold power over other duchies or sit just below a crown; too many grand duchies cheapen the title.
  • Name the ducal seat after the duchy (Vessemark's capital can simply be Vessemark or Vessemark Castle) to keep your setting easy for players to follow.
  • Descriptive names like Duchy of the Marches or Duchy of the Twin Rivers work best for territories defined by geography rather than an old tribe or family.
  • Real historical duchies are fine for alternate-history games but can distract in a wholly invented world; swap them for original names there.

Frequently asked questions

How were medieval duchies actually named?

Nearly always after a place, region or people rather than a family: Bavaria after the Bavarii, Normandy after the Northmen, Brabant after an old Frankish pagus. Hyphenated names such as Saxe-Coburg came later when dynasties partitioned their lands.

What is the difference between a duchy, a grand duchy and an archduchy?

A duchy is ruled by a duke. A grand duchy is a sovereign or near-sovereign state ruled by a grand duke, like Luxembourg today. Archduchy was essentially a Habsburg title used for Austria and ranked just below a kingdom.

Are these duchy names good for Crusader Kings or Bannerlord?

Yes. Many of the historical names match de jure duchies you will see in Crusader Kings, and the invented ones fit the naming style of custom kingdoms and Bannerlord mods.

Can I use these names in a published book or game?

Historical duchy names are public knowledge and the original names here are free for personal and commercial use, no attribution needed.
