Counts · Held directly of the king · as at first light, 1 January 1200

Boulogne

A childhood friend of Philip Augustus who fought for the Angevins in Richard's last wars, Renaud holds the Channel county of Boulogne by a forced marriage to its heiress.

On 1 January 1200 he is still counted among the Angevin allies, but his ally Baldwin makes his peace with the king the next day, leaving Renaud exposed. At Le Goulet (22 May 1200) John recognises the counts of Boulogne and Flanders as the French king's vassals and gives them up, and Renaud is received back into the king's favour.

Who he is

Name
Renaud of Dammartin (Renaud de Dammartin), with Countess Ida of Boulogne
Title
Count of Boulogne in right of his wife; heir to the county of Dammartin
Since
1190-1191 (his marriage to Ida, arranged by abduction by his father Aubry)
Born
Renaud about 1165 (about 35); Ida about 1160 (about 40)
Family
Renaud is the eldest son of Aubry (Alberic) III, count of Dammartin, still alive. Ida is the daughter of Matthew of Alsace and Mary of Blois, so a granddaughter of King Stephen of England and a first cousin of Baldwin IX; widowed twice (Gerard of Guelders, Berthold of Zahringen) before Renaud. Their only child, Matilda (Mahaut), is born about 1200-1202: not pinned whether she is born on 1 January 1200.
Confidence

English Wikipedia (Renaud I, Count of Dammartin; Treaty of Le Goulet). His formal allegiance on 1 January 1200 is inferred, see notes.

Overlord

The king of France: since 1191 the homage of Boulogne belongs to the king with Artois, and the treaty of Peronne keeps it so.

What it holds

  • Boulogne: the castle, the port and the shrine of Notre-Dame
  • Calais and the Calaisis
  • Wissant, the old crossing to England
  • Etaples on the Canche, Desvres, Samer, Marquise and the Boulonnais forests
  • Claims to the old English honour of Boulogne (not pinned)

How it was acquired

Marriage to Ida, 1190-1191; the king accepted the match and took the homage.

Allies and rivals

Allies: John (since 1199) and Baldwin IX. Rivals: the house of Guines (Arnold was Ida's betrothed), the Dreux family. Old friend of the king.

How things stand that morning

Renaud and Ida hold the Boulonnais. Formally Renaud is John's ally that morning (medium confidence); in practice he is waiting on the Flemish peace.

Wealth

The Channel crossing, herring fisheries, salt, the pilgrimage to Notre-Dame of Boulogne, the forest of Boulogne.

Military

Castle of Boulogne; the ports' ships.

Threats

  • Being left alone when Baldwin makes peace
  • The king's anger
  • Guines

  • Wissant: Crossing to Dover

Where the sources disagree

  • Renaud's allegiance on 1 January 1200 is not settled by a dated document found here; the assignment's question is answered by inference from the alliances of 1197-1199 and the Le Goulet clause.

Evidence: His career is well known in outline; the months of his return to Philip are not pinned here.

On the map: Approximate, especially towards Guines.
