Renaud, Count of Dammartin

Renaud de Dammartin (Reginald of Boulogne) (c. 1165 – 1227) was Count of Boulogne from 1190, Count of Dammartin from 1200 to 1214 and Count of Aumale from 1204 to 1214. He was son of Albéric II de Dammartin, and Mathilde de Clermont.

Brought up at the French court, he was a childhood friend of Philip Augustus. At his father's insistence he fought for the Plantagenets. Received back into Philip's favour, he married Marie de Châtillon, daughter of Guy II de Châtillon and Alix de Dreux, a royal cousin.

On Philip's advice, he then set aside Marie, and forcibly married Ide de Lorraine (died 1216), who was countess of Boulogne and widow of Bertold IV de Zähringen, daughter of Mathieu d'Alsace and Marie de Boulogne, who had been count and countess of Boulogne. The County of Boulogne thereby became vassal to the French king, rather than the count of Flanders. While this marriage made Renaud a power, it also made enemies in the Dreux family and that of the count of Guînes, who had been betrothed to Ide.

In 1203, Renaud and his wife gave a merchant's charter to Boulogne. This was probably made for financial consideration. Philip made Renaud count of Aumale the following year, but Renaud began to detach himself. Following the acquisition of Normandy in April 1204, King Philip granted Renaud the county of Mortain and the honor of Warenne which was centered on the fortresses of Mortemer and Bellencombre. Both Mortain and Warenne had been held by William of Blois, second son of King Stephen of England, and it would appear that King Philip recognized the Boulogne claim to them.

In 1211, he refused to appear before Philip in a legal matter, a suit with Philippe de Dreux, bishop of Beauvais. Then he came to terms with John of England, rendering homage to him in 1212.

With the Emperor Otto IV and Ferrand of Flanders, he took part in the attack on France in 1214 culminating in the Battle of Bouvines. He was on the losing side, but was one of the last to surrender, and refused submission to Philip Augustus. His lands were taken away, and given to Philippe Hurepel. Renaud was kept imprisoned at Péronne for the rest of his life. His daughter Mathilde de Dammartin was married to Philippe Hurepel. She later married Alphonso III of Portugal.
