The imperial county between the Scheldt and the Sambre that Baldwin inherited from his father: Mons with its castle and the chapter of Sainte-Waudru, Valenciennes on the Scheldt where he was born, Binche, Maubeuge, Le Quesnoy, Ath and Beaumont, and the Ostrevant with Bouchain.
Hainaut is a land of peers, castellans and abbeys, held in personal union with Flanders and run day to day by the count's bailiff, Robert of Jemappes, who sits in the count's court at Valenciennes. Namur is held of Hainaut by Baldwin's brother Philip.

Overlord
The bishop of Liege, of whom the county has been held in fief since 1071, and the emperor (a disputed throne in 1200). The Ostrevant on the French side of the Scheldt is a separate tie.
What it holds
- Mons (castle, the count's lay abbacy of Sainte-Waudru)
- Valenciennes (the Salle-le-Comte, the town and the prevote)
- Binche (castle and town, traditionally a dower town of the countesses)
- Maubeuge (the town by the abbey of Sainte-Aldegonde)
- Le Quesnoy, Bavay, Beaumont, Ath, Braine-le-Comte, Halle
- The Ostrevant with Bouchain and Denain
- Overlordship of the peers of Hainaut (Avesnes, Chimay, Barbencon, Rumigny, Trazegnies and others) and of Namur
How it was acquired
Inheritance from Baldwin V (died 17 December 1195).
Allies and rivals
Ally: his brother Philip of Namur. Neighbours: Brabant to the north-east, the bishop of Liege (Thuin, Lobbes) to the east, the bishop of Cambrai to the west, the king's Vermandois and Thierache to the south.
How things stand that morning
Quiet. The war with Theobald of Bar over Namur ended at Dinant on 26 July 1199. The count is away in Flanders and Artois for the peace with the king; Hainaut is run by the bailiff Robert of Jemappes with the peers, among whom Walter of Avesnes and Alard of Chimay stand closest to the count.
Wealth
Rents, tolls on the Scheldt at Valenciennes and Conde, the cloth of Valenciennes and Maubeuge, forests (Mormal), the count's demesne farms; poorer in cash than Flanders.
Military
Knights of the peers and castellans; castles at Mons, Valenciennes, Binche, Le Quesnoy, Bouchain, Ath, Beaumont.
Threats
- The bishop of Liege's overlordship
- Brabant
- The count's absence on 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.
- 28 July 1200At the castle of Mons Baldwin issues the two general charters of Hainaut: the feudal charter (inheritance of fiefs and allods, wardship, majority) and the penal charter, 'the form of peace in the whole county of Hainaut' (feuds, abjuration, fines). The feudal charter gives the bailiff of Hainaut authority over inheritance disputes.Depends on: Peace and the count's presence. Stopped by: War or absence.
Places of note
- Castle of Mons: Count's castle above Sainte-Waudru
- Salle-le-Comte: Count's palace
- Bouchain: Castle of the Ostrevant
Where the sources disagree
Evidence: Gislebert of Mons describes Hainaut in detail to 1195; for 1200 the outline is clear, the officers thin.
On the map: A rough outline; the Avesnes lands and the Namur march are drawn under their own records.
