Marie I, Countess of Boulogne

Marie was the younger daughter of King Stephen of England and his wife Matilda I, Countess of Boulogne.[1] She was born in 1136, one year after her father had succeeded to the English throne. His reign was to be marked by the civil war known as "The Anarchy" during which he fought a series of battles to retain the crown which was claimed by his cousin Empress Matilda. Marie had three brothers, Eustace, William, Baldwin, and one sister, Matilda.

Marie became a novice at the Priory of Lillechurch in Kent, but later transferred to Romsey Abbey in Hampshire.[1] The abbey had been rebuilt by her uncle Henry of Blois, Bishop of Winchester. It was at Romsey that she became a nun sometime between 1148 and 1155. She was elected Abbess of Romsey in 1155,[1] the year following her father's death and the subsequent ascension to the English throne of Empress Matilda's son Henry II.

About four years later, on 11 October 1159, her brother William died in Toulouse. As his marriage to Isabel de Warenne, Countess of Surrey had been childless, Marie, his only surviving sibling, succeeded as the suo jure Countess of Boulogne.

Matthew of Alsace abducted Marie from the abbey in 1160,[2] and forced her to marry him in defiance of her religious vows.[1] He therefore became jure uxoris Count of Boulogne and co-ruler. On 18 December 1161, Pope Alexander III wrote a letter to the Archbishop of Rheims in which he discussed Marie's abduction by Matthew of Alsace and her subsequent constrained marriage. The couple had two daughters.

Marie's marriage to Matthew was annulled in 1170. This was the same year that she gave birth to their younger daughter, Mathilde, in Louvain.

Following the annulment, Marie re-entered the religious life as a Benedictine nun at St. Austrebert, Montreuil,[1] where she died on 25 July 1182 at the age of about 46. Her former husband Matthew continued to reign as Count of Boulogne until his death in 1173, when their eldest daughter Ida succeeded as countess. Following the death of Ida's daughter, Matilda II, the county of Boulogne eventually passed to Adelaide of Brabant, daughter of Marie's second daughter, Mathilde.
