The counts of Brienne hold the castle of Brienne and a compact county on the Aube between Troyes and the Der, one of the great vassal counties of Champagne.
Walter III is a crusader's son with an eye on a crown: Tancred's widow Sibylla and her daughters escaped from German captivity to France, and Walter is about to marry the eldest, Elvira, and claim her inheritance in Apulia. On 1 January 1200 he is still in France: the marriage at Melun and the Italian venture lie ahead.
Who he is
- Name
- Walter III of Brienne (Gautier III de Brienne)

- Count of Brienne
- Since
- 1191, on the death of his father Erard II at the siege of Acre
- Born
- After 1166 (not pinned)
- Family
- Son of Count Erard II and Agnes of Montbeliard. Brothers: John (born about 1170-75, the future king of Jerusalem), William (lord of Pacy, husband of Eustachie of Courtenay, died between 1194 and 1199), Andrew. Sister Ida, wife of Arnoul of Reynel. His cousin Erard holds Ramerupt (Ramerupt).
- Confidence
- high
Married Elvira (Albinia) of Sicily, daughter of King Tancred, at Melun in 1200 at a meeting called by Philip II (fmg gives 'Melun 1200'; Alberic of Trois-Fontaines gives 1201). He took the cross after Ecry, sold or pledged his lands by April 1201 and reached the kingdom of Sicily by late spring 1201 (English Wikipedia). Died of wounds in June 1205.
Overlord
Theobald III, count of Champagne
What it holds
- Brienne: castle and small town on the Aube (Brienne-le-Chateau), with the villages of the Aube valley around it
- The county's justice, tolls on the Aube and woods
- Herbisse, held by his brother John until he exchanges it with Count Theobald by a charter dated March 1200 (fmg; March 1201 if the year is counted from Easter, so John probably still holds it on 1 January 1200)
How it was acquired
Hereditary in the house of Brienne since the tenth century; held of the counts of Champagne.
Allies and rivals
Philip Augustus, who arranges the Melun marriage; Innocent III, whose recognition he needs; the Champagne crusaders. Enemies to come: the German captains in Apulia (Diepold of Vohburg) and Markward. Earlier quarrels in the 1190s with Peter of Courtenay and Herve of Donzy.
How things stand that morning
Held and governed by Walter in person; he has taken the cross and is negotiating his Sicilian marriage.
Wealth
Aube valley land, mills and woods; he will sell or pledge much of it by April 1201 to fund Italy.
Military
Castle of Brienne; household knights. Takes a small force to Italy in 1201.
Threats
- Over-reach in Italy
- Debt from selling and pledging his lands
- His crusade vow, which he will turn to Apulia
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.
- 1200Marries Elvira of Sicily at Melun before Philip II (Alberic dates it 1201).Depends on: Philip's goodwill and Sibylla's consent. Stopped by: A rival match or the king's refusal.
- 1200 to spring 1201Seeks Innocent III's recognition of Elvira's claims to Lecce and Taranto; the pope recognises them but not her claim to the Sicilian throne. Walter sells or pledges his lands and leaves for Italy, leaving his brother John in charge of Brienne.Depends on: The pope's support against the German captains. Stopped by: Innocent refusing; lack of money.
Places of note
- Castle of Brienne: Seat of the counts.
Where the sources disagree
- The assignment describes Walter as 'away in southern Italy' on 1 January 1200. The sources place his marriage at Melun in 1200 (or 1201) and his arrival in the kingdom of Sicily in late spring 1201, so on 1 January 1200 he is in France. The Annales Ceccanenses mention him expelling Diepold from a castle under 1199 (fmg), which looks misdated.
Evidence: Walter's Italian career is well documented; the extent of the county in 1200 is reconstructed.
On the map: Only the core around Brienne is drawn; outlying fiefs are not pinned.
