Margaret's husband was killed in the
Battle of Crécy on 26 August 1346. He and Margaret had one son, Count
Louis II of Flanders, who succeeded his father and for whom she acted as a regent in the beginning of his reign. In 1357, Margaret's granddaughter,
Margaret, then seven years old, was married to Duke
Philip I of Burgundy, grandson and heir of Margaret's sister. They were childless and, upon his death in 1361, the elder Margaret succeeded to the comital thrones of Artois and Burgundy. In 1369, the younger Margaret married
Philip the Bold, youngest son of King
John II of France. According to Guizot, whilst Margaret I favoured the marriage of her granddaughter to Philip the Bold, the girl's father, Louis II, and the Flemish communes, preferring England to France, were unwilling to arrange the marriage. Reputedly, Margaret, ''vexed at the ill will of the count her son, had one day said to him, as she tore open her dress before his eyes, "Since you will not yield to your mother's wishes, I will cut off these breasts which gave suck to you, to you and to no other, and will throw them to the dogs to devour." '' Louis, persuaded, agreed to the marriage. The unrest in coastal Low Countries escalated to open rebellions in Margaret's last years. A revolt in
Ghent was put down by joint operation of Margaret's son and grandson-in-law. However, after the
Battle of Beverhoutsveld, Louis II was expelled from Flanders by the Flemings under
Philip van Artevelde. A French army (and Philip the Bold) came to help them regain Flanders, and the revolting Flemings were decisively defeated at the
Battle of Roosebeke, the year in which Margaret died. However, the citizens of Ghent continued to resist with
English aid, and it was left to her granddaughter and grandson-in-law to subdue the town. ==Death==
