The Joinvilles hold the castle and town of Joinville on the Marne at the eastern edge of Champagne, facing the county of Bar, and the hereditary seneschalcy of Champagne, the first lay office of the count's household.
Geoffrey V is a crusader of the Third Crusade, unmarried, and has sworn the cross again at Ecry: he means to go East, and his heir is his brother Simon.
Who he is
- Name
- Geoffrey V of Joinville, called Trouillart (Geoffroy V de Joinville)
- Title
- Lord of Joinville, hereditary seneschal of Champagne
- Since
- 1190, when his father Geoffrey IV died at the siege of Acre (August 1190)
- Born
- Not pinned
- Family
- Son of Geoffrey IV of Joinville and Helvide of Dampierre (so a nephew of Guy II of Dampierre). Unmarried and childless. Brothers: Robert, Simon (his heir, father of the chronicler John of Joinville) and William, archdeacon in 1191 and later bishop of Langres (1209) and archbishop of Reims (1219).
- Confidence
- high
A charter of 1191 calls him lord of Joinville and seneschal of Champagne, another of May 1196 'senescallus Campanie' (fmg). He took the cross again in 1199, left for the Holy Land in late 1201 with his brothers Robert and Simon, and died in late 1203 or early 1204 fighting at the Krak des Chevaliers (French Wikipedia).
Overlord
Theobald III, count of Champagne
What it holds
- Joinville: castle on its spur over the Marne and the town below
- Villages of the Marne valley around Joinville (Thonnance, Vecqueville, Mussey, Fronville, Rupt, Suzannecourt) and the woods towards Poissons
- The hereditary seneschalcy of Champagne
- The advocacy (protection) of the abbey of Saint-Urbain on the Marne, long disputed with the monks
- Fiefs in the Barrois held of the count of Bar (not itemised; not pinned)
How it was acquired
Joinville is the family's since the eleventh century (fmg traces the line to Etienne de Vaux). The seneschalcy came to the family in the mid twelfth century (William of Joinville is named seneschal in 1153, fmg).
Allies and rivals
Allies: the count; his uncle Guy of Dampierre; the Brienne brothers (Robert of Joinville will follow Walter of Brienne to Apulia). Rivals: the monks of Saint-Urbain over the advocacy; neighbours in the Barrois.
How things stand that morning
Held. Geoffrey is in Champagne preparing for the crusade.
Wealth
Marne valley lands, woods, the advocacy of Saint-Urbain, the profits of the seneschalcy.
Military
Castle of Joinville; household knights; leads the count's household as seneschal.
Threats
- A childless lord about to leave for the East
- The abbey of Saint-Urbain's complaints at the count's court and in Rome
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- late 1201 (later course)Geoffrey leaves for the Holy Land with his brothers; he dies at the Krak des Chevaliers in late 1203 or early 1204 and Simon inherits Joinville.Depends on: The crusade going ahead. Stopped by: The crusade collapsing or the count holding him at home.
Places of note
- Castle of Joinville: Seat of the lords of Joinville.
- Abbey of Saint-Urbain: Abbey whose advocacy the Joinvilles hold and quarrel over.
Where the sources disagree
Evidence: Charters of 1191 and 1196 fix him as seneschal; the list of Joinville's villages in 1200 is not pinned.
On the map: Only the core around the castle is drawn; outlying fiefs and Barrois holdings are not.
