누가 Margherita II delle Fiandre와 결혼 했습니까?

Margherita delle Fiandre, o di Hainaut o di Costantinopoli (Valenciennes, 2 giugno 1202 – Gand, 10 febbraio 1280), fu contessa delle Fiandre dal 1244 al 1278 e contessa di Hainaut (Margherita I) dal 1244 al 1253 e di nuovo dal 1257 alla morte.

Burchard IV or Bouchard IV (1182–1244) was the lord of Avesnes and Étrœungt. He was the son of James of Avesnes and Adela of Guise and brother of Walter, Count of Blois.

Bouchard began his career as a cantor and subdeacon in the church of Laon. In 1212, he was named bailiff of Hainaut. In this capacity, he served as tutor and guardian of the young Margaret, daughter of Baldwin VI of Hainault and sister of Joanna, Countess of Flanders and Hainault. He later married Margaret in 1212, though she was only ten years old and the marriage could not be consummated. Neither Joanna nor her husband, Count Ferdinand, gave their consent and tried to halt the marriage but failed.

Bouchard invaded the territory of his brother Walter, who had received most of their patrimony. He then invaded Flanders and forced Joanna and Ferdinand to recognise his marriage to Margaret. He fought at the Battle of Bouvines in 1214, under the (losing) Flemish banner. Philip Augustus, the king of France and victor of Bouvines, then counselled the pope, Innocent III, to declare Bouchard's marriage illegal. When Innocent eventually excommunicated Bouchard on 19 January 1216, he and Margaret took refuge in Luxembourg. In 1219, Bouchard was captured in battle and would be imprisoned in Ghent for two years. To obtain his release, Margaret accepted the dissolution of her marriage and Bouchard left for Italy to fight for the Holy See. Upon his return, he was decapitated at Rupelmonde on the orders of Joanna.

Bouchard and Margaret had three children, who played an important part in the War of the Succession of Flanders and Hainault:

• Baldwin (1217–1219), took refuge with his parents in Luxembourg
• John I (1218–1257), later Count of Hainault
• Baldwin (1219–1295), Lord of Beaumont

William II (1196 – 3 September 1231) was the lord of Dampierre from 1216 until his death. He was the son of Guy II, constable of Champagne, and Mathilde of Bourbon.

His brother, Archambaud VIII, inherited Bourbon, and William inherited Dampierre. He married Margaret II, Countess of Flanders and Hainault, in 1223 and was thus regent of Flanders until his death as "Willem I" (or "Guillaume I^er"). In 1226 William and Margaret founded a Cistercian nunnery at Saint-Dizier. Their sons William III and John continued to confirm and patronize the nunnery during their lives, including William II's burial there in 1231. William and Margaret founded more Cisterian nunneries throughout the county of Flanders, including Flines Abbey.
