Life
Margaret′s father Peter Courtenay, Latin Emperor of Constantinople (d. 2019)

Margaret (also called Sybille, in some later sources) married Raoul, Lord of Issoudun c. 1208, who should not be confused with Raoul I of Exoudun (d. 1219). Her husband died c. 1213/5 and Margaret succeeded him as Lady of Châteauneuf-sur-Cher and Mareuil-en-Berry. Soon after that (c. 1216) she married Henry I, Count of Vianden (d. 1252). Henry was the son of Frederic III, Count of Vianden (d. 1217), and his wife Matilda (de).

In 1216, Margaret′s father Peter Courtenay (d. 1219) was elected Latin Emperor of Constantinople, and crowned in Rome by Pope Honorius III on 9 April 1217. He was succeeded by son Robert of Courtenay (Margaret′s brother) who ruled as Emperor of Constantinople until 1228, when he was succeeded by their brother Baldwin II of Constantinople. Since the elevation to the imperial throne in Constantinople (1216), Margaret′s family became involved in creation of new dynastic policies and alliances.[1]

Marchioness of Namur

Margaret became Marchioness of Namur after the death of her brother Henry II, Marquis of Namur in 1229, who had succeeded another brother, Philip II. Their grandfather had received the county as an inheritance as a nephew of Henry IV, Count of Luxembourg (Henry I of Namur). Margaret and her husband Henry I of Vianden (Henry III of Namur) ruled Namur until 1237, when they had to transfer Namur to Margaret's brother Baldwin II of Courtenay.[2]

Henry and Margaret continued ruling Vianden. Henry V, Count of Luxembourg (1216 – 1281), maternal grandson of Henry IV, Count of Luxembourg (Henry I of Namur), invaded Namur and ruled it 1256-1264 as Henry IV (or III ?). Baldwin sold Namur in c. 1263 to his cousin Guy of Dampierre, count of Flanders and Henry was removed by military force but they made peace with family marriage.

Later life

After the death of her husband in 1252, Margaret entered a convent in Marienthal near Luxembourg and became a nun. She died in Marienthal on 17 July 1270 and was buried there.[3]

Issue

Margaret and Henry had several children, including:[4]
