The counts of Roucy hold the castle of Roucy on its hill south of the Aisne between Reims and Laon, with Neufchatel and Pontavert on the river.
The line is ending: Count John I is childless, and Enguerrand III of Coucy, the most ambitious baron of the Laonnois, will grab the county in 1200 by marriage before the heiress Eustachie recovers it.
Who he is
- Name
- John I of Roucy (Jean Ier de Roucy)
- Title
- Count of Roucy
- Since
- 1196, on the death of his brother Raoul I, who left only a daughter who became a nun
- Born
- Not pinned
- Family
- Son of Count Guiscard (1160-1180) and Elisabeth of Mareuil, lady of Neufchatel-sur-Aisne. Wife: Beatrice of Vignory (so the lists say; the Vignory family history is less sure). No legitimate children. His niece Eustachie, Guiscard's daughter, is the heiress.
- Confidence
- medium
English and French Wikipedia lists: John I 1196-1200, then Enguerrand III of Coucy from 1200 (by marriage; the lists disagree whether to John's widow or to Eustachie) until about 1204-05, then Eustachie and her husband Robert of Pierrepont. John is presumed alive on 1 January 1200; the day of his death in 1200 is not pinned.
Overlord
Theobald III, count of Champagne, for the county (by the later tradition that counts Roucy among the counts-peers of Champagne); the archbishop of Reims has rights nearby. Not pinned for 1200.
What it holds

How it was acquired
Hereditary since the tenth century; the house of Montdidier-Roucy holds it in 1200.

How things stand that morning
Held by a childless count with a disputed succession ahead.
Wealth
Aisne river traffic and lands.
Military
Castle of Roucy.
Threats
- Extinction of the male line
- Enguerrand III of Coucy
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.

Stopped by: John living, or the count of Champagne or the king refusing Enguerrand.
Where the sources disagree
- Whether Roucy is held of Champagne or of the king in 1200 is not settled by our sources: the Royal assignment leaves Roucy to Champagne if Champenois. We have put it in Champagne on the later tradition of the counts-peers of Champagne; treat as medium.
Evidence: Succession lists only; the overlordship in 1200 is not pinned.
On the map: Reconstructed around the castle.
