Baldwin's brother Philip holds Namur, the fortress-town at the meeting of the Sambre and the Meuse, as a fief of Hainaut.
Theobald I of Bar, husband of Ermesinde of Luxembourg, the late Henry the Blind's daughter, claimed Namur and made war on him from 1196 and besieged him in the town. In July 1199, while Philip was a prisoner of the French king, Baldwin made the treaty of Dinant with Theobald (26 July 1199): Philip keeps Namur, but a large part of the county on the right bank of the Meuse goes to Theobald, at first without any compensation for Philip. On 1 January 1200 Philip may still be in the king's hands; his release is a natural term of the coming peace.
The old chancellor of Hainaut, Gislebert of Mons, now works mostly for him at Namur.

English Wikipedia (Philip I, Marquis of Namur); Ruffini-Ronzani 2024 for his captivity in July 1199 and the terms of Dinant.
Overlord
His brother Baldwin, as count of Hainaut, of whom Namur is held in fief; the emperor above (Namur was made a margraviate by imperial grant for Baldwin V).
What it holds
- The castle and town of Namur
- The county on the left bank of the Meuse: the land between the Sambre and the Meuse west of the river, Floreffe and the march towards Brabant to the north
- Bouvignes on the left bank opposite Dinant
- Advocacies of the Namur abbeys (Floreffe, Malonne, Brogne)
- Lost in July 1199: the lands on the right bank of the Meuse, ceded to Theobald of Bar at Dinant
How it was acquired
Bequest of Baldwin V, who won Namur from his uncle Henry the Blind (battle of Noville-sur-Mehaigne, 1 August 1194); the treaty of Dinant (26 July 1199), made by Baldwin while Philip was a prisoner, kept Namur for him but gave the right bank of the Meuse to Theobald of Bar.
Allies and rivals
Brother Baldwin; rival Theobald I of Bar and Luxembourg (peace since July 1199); neighbours the bishop of Liege (Dinant, Fosses, Thuin) and the duke of Brabant (Gembloux, Nivelles).
How things stand that morning
Namur and the left bank are his; across the Meuse the ceded right-bank lands are Theobald of Bar's (East researcher); Dinant and the Condroz are the bishop of Liege's; to the north the duke of Brabant. Philip himself may be a captive in France that morning (not pinned).
Wealth
Meuse tolls, the Namur market, metal working, quarries and forests.
Military
The rock castle of Namur, which held against Theobald's siege; Bouvignes.
Threats
- A renewed claim from Bar-Luxembourg
- Liege and Brabant
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.
In 1200
- January 1200 (not pinned)If he is still a prisoner, Philip is freed as part of the peace between Baldwin and the king made at Peronne on 2 January.Depends on: The peace of Peronne and the king's goodwill. Stopped by: A breakdown of the peace; the king keeping him as a hostage.
- 28 July 1200Seals, with his brother and the leading Hainaut barons, the two general charters of Hainaut at the castle of Mons.Depends on: His freedom and the peace. Stopped by: Captivity or war.
Later, on the likely course
- 1202Guardian of Baldwin's daughters and regent when Baldwin leaves on crusade (14 April 1202).Depends on: Baldwin's departure. Stopped by: The crusade not sailing.
Places of note
- Castle of Namur: Rock castle at the Sambre-Meuse confluence
Where the sources disagree
- English Wikipedia says only that the treaty of Dinant (26 July 1199) recognised Philip as holder of Namur; Ruffini-Ronzani (2024) adds that Baldwin made it while Philip was the French king's prisoner and that it gave Theobald of Bar a large part of the county on the right bank of the Meuse. The map follows the second.
Evidence: Dinant and the captivity of July 1199 are attested; the date of his capture and release and the exact line of the 1199 cession are not pinned.
On the map: A rough outline; the 1199 cession is drawn along the Meuse itself.
