A border principality between Normandy, Maine and the Chartrain: Mortagne, Bellême and Nogent-le-Rotrou with the forests of the Perche.
Count Geoffrey is the king of France's first cousin and the king of England's nephew by marriage, and holds of both. Which side he is on this winter is not pinned: the leaning is to John (his wife, his English manors, Bellême held of the duke), but he fought Richard in 1193-94 and is turning to the crusade.
Who he is
- Name
- Geoffrey III (Geoffroy III du Perche)
- Title

- 1191, after his father Rotrou IV was killed at the siege of Acre
- Born

- Family
- Son of Rotrou IV and Matilda of Blois-Champagne, so first cousin of Philip Augustus, Theobald III of Champagne and Louis of Blois. Wife (married 1189 at Rouen): Matilda of Saxony (born 1172), daughter of Henry the Lion, niece of John and sister of Otto IV.

In 1193-94 he sided with John (then allied to Philip) against the captive Richard; in 1194 he took Moulins and Bonsmoulins, which his father had ceded to Henry II; Richard imprisoned him and seized his lands until autumn 1195. He took the cross with his brother Stephen (Villehardouin; date not pinned, late 1199 or early 1200) and dies at Soissons in Lent 1202 before sailing.
Overlord
Philip II for Mortagne and Nogent; John, duke of Normandy, for Bellême; Richard and John for his English manors
What it holds
- Mortagne, the comital seat
- Bellême and its forest, held of the duke of Normandy
- Nogent-le-Rotrou and its castle
- Longny, Remalard and the forests of the Perche
- Moulins-la-Marche and Bonsmoulins, taken from Normandy in 1194; probably still the count's in 1200, since Philip took them from the Perche inheritance only after 1217
- Patronage of La Trappe and Thiron
- English manors in Suffolk, Essex and Kent granted by Richard (1189-90), once Henry of Essex's
How it was acquired
Inherited 1191.
Allies and rivals
Kin on both sides: Philip, Theobald III and Louis of Blois (cousins); John and Otto IV (by marriage). Neighbours: the count of Alencon, the lords of Maine, the Montfort-Evreux and Chateauneuf-en-Thymerais lords.
How things stand that morning
Holds his county. Allegiance on 1 January 1200 not pinned in the sources checked: leaning to John, but likely neutral under the truce and bound for the crusade. Realm is set to crown because Mortagne and Nogent answer to the king of France; Bellême is drawn as a separate part held of the duke.
Wealth
Forests and iron of the Perche, tolls on the roads from Chartres to Alencon and Le Mans, Nogent's market; he sold tolls to abbeys to pay crusade debts after 1191.
Military
Castles of Mortagne, Bellême, Nogent-le-Rotrou; a crusading household.
Threats
- Being caught between the kings on the Norman march
- Crusade debts
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.
- 1200, date not pinnedTakes or confirms his crusade vow with Stephen and the barons of the Perche, which removes him from the war.Depends on: The Ecry movement Stopped by: War on his borders
Places of note
- Bellême: Castle held of the duke of Normandy
- Nogent-le-Rotrou: Castle Saint-Jean
Where the sources disagree
- Allegiance not pinned; the campaign may rule. Medieval Lands and Kathleen Thompson's study of the Perche (Power and Border Lordship, 2002) are the sources to settle it.
Evidence: Family and lands fair; his side in 1199-1200 is inferred, not documented here.
On the map: The Perche-Gouet (Brou, Montmirail, Authon) is not the count's and is left out; the county's edge is approximate.
