Counts · County of Champagne · as at first light, 1 January 1200

Count's demesne

The land the count holds in his own hand: castles, towns, markets, mills, woods, tolls and courts, run by his prevots and castellans, with the knights of each castellany owing him guard and the host.

It is not one block but a chain of castellanies along the Seine, the Aube and the Marne, from Montereau and Lagny in the west to Vitry, Sainte-Menehould and the Bassigny in the east, with the great vassal counties and baronies set between them. Seven castellanies (Epernay, Vertus, Sezanne, Chantemerle, Pont-sur-Seine, Nogent-sur-Seine, Mery-sur-Seine) were assigned as Blanche of Navarre's dower at her marriage in July 1199: the count still holds them, but they would be hers if he died.

Who he is

Name
Theobald III (Thibaut III)
Title
Count palatine of Troyes, count of Champagne and Brie
Since
1197
Born
13 May 1179, Troyes
Family
House of Blois-Champagne; see the realm record Champagne
Confidence
high

The castellanies are those of the Feoda Campanie of 1172 and of the dower charter of 1199 (Blanche's seven castellanies); a list for 1 January 1200 itself does not survive, so the drawing is a careful reconstruction.

Overlord

Philip II of France (liege homage)

What it holds

  • Troyes: the palace, the fairs of Saint-Jean and Saint-Remi, the mint, the Jews, the prevote; the viscounty is held of him by the lords of Chappes
  • Provins: the castle and great tower on the upper town, the May and Saint-Ayoul fairs, the main mint of the provinois deniers
  • Lagny: the January fair (the abbey of Saint-Pierre owns the town; the count protects it and the fair)
  • Bar-sur-Aube and La Ferte-sur-Aube: castle, Lenten fair, Aube valley vineyards
  • Meaux: the count's share of the city (castle and Marche) beside the bishop; the commune of 1179 was his father's grant
  • Coulommiers, Chateau-Thierry, Oulchy, Fismes: castles and prevotes of the Brie and the Marne
  • Montereau and Bray-sur-Seine: castles on the Seine (Bray and Montereau are the two Blanche hands to Philip in 1201)
  • Blanche's dower (assigned July 1199): Epernay, Vertus, Sezanne, Chantemerle, Pont-sur-Seine, Nogent-sur-Seine, Mery-sur-Seine
  • Isle (Isle-Aumont), Villemaur, Ervy, Saint-Florentin: castellanies of the Othe and the Armance south-west of Troyes
  • Vitry (Vitry-en-Perthois), Rosnay, Wassy: castellanies of the Perthois and the Der; the count is advocate of Montier-en-Der
  • Sainte-Menehould: castle on its rock in the Argonne, comital by the end of the twelfth century (not pinned more closely)
  • Monteclair (by Andelot) in the Bassigny: comital castle
  • Chaumont in the Bassigny: not pinned. Its own lords held it until about 1190 and it was the count's by 1205 at the latest (French Wikipedia)

How it was acquired

The core (Troyes, Meaux, Provins) came to the house of Blois in the 1020s; Bar-sur-Aube and Vitry in the twelfth century; Sainte-Menehould by the end of the twelfth century. The castellany system and the register of fiefs are the work of Henry I the Liberal (1152-1181).

Allies and rivals

See Champagne. Inside the demesne the count's partners and rivals are churches: the bishop of Meaux in Meaux, the abbey of Lagny at Lagny, the chapters of Troyes and Saint-Etienne, the abbey of Montier-en-Der.

How things stand that morning

Held in peace. The dower castellanies are assigned to Blanche but administered by the count. No castle is in the king's hands yet: Bray and Montereau pass to Philip only in May 1201.

Wealth

Fair dues, tolls on the Seine and the Marne, the mints, Jewish taxes, mills, ovens, vineyards (Epernay, Ay, Bar-sur-Aube), woods (the Othe, the Der, the Brie forests), rents and the profits of justice.

Military

Castles at Troyes, Provins, Meaux, Chateau-Thierry, Montereau, Bray, Sezanne, Epernay, Vitry, Sainte-Menehould, Bar-sur-Aube, Rosnay, Wassy and Monteclair. The vassals of each castellany owe castle guard there and come to the host by castellany (Feoda Campanie, 1172).

Threats

  • The dower castellanies would leave the count's hand at his death
  • The king's appetite for the Seine castles (Bray, Montereau)
  • Pledges and sales to pay for the crusade

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.

  1. May 1201 (later course)After Theobald's death Blanche surrenders Bray-sur-Seine and Montereau to Philip as security; the king keeps them until Theobald IV comes of age in 1222.Depends on: Theobald dying on 24 May 1201. Stopped by: Theobald living.

Places of note

  • Great tower of Provins: The count's castle on the upper town.
  • Castle of Chateau-Thierry: Comital castle over the Marne.
  • Castle of Montereau: Comital castle at the Seine and Yonne confluence.
  • Castle of Bray: Comital castle on the Seine; the Jews burned there by Philip in 1192.
  • Monteclair: Comital castle over Andelot in the Bassigny.

Where the sources disagree

Evidence: The comital castellanies are well known from the Feoda Campanie and the dower charter; their bounds in 1200 are reconstructed, and Chaumont and Fismes are not pinned for 1 January 1200.

On the map: Castellanies are drawn from their castles and a few edge villages; bounds are approximate and vassal fiefs inside them are not cut out. Chaumont is left to its town record because its holder on 1 January 1200 is not pinned.
