Qui es va casar amb Margherita II delle Fiandre?

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

Guillem II de Dampierre (1196 - 3 de setembre de 1231) va ser senyor de Dampierre. Era fill de Guiu II de Dampierre i Matilde I de Borbó.

El seu germà, Arquimbald VIII, va heretar la Senyoria de Borbó, mentre que Guillem heretà la de Dampierre.

En casar-se amb Margarida II de Flandes, comtessa de Flandes i d'Hainaut va ser conegut també, al Comtat de Flandes, com el regent "Guillem I de Dampierre". Van tenir diferents fills:

• Guillem III de Dampierre, comte de Flandes
• Guiu de Dampierre, comte de Flandes i comte de Namur
• Joana de Dampierre, casada amb Hug III de Rethel i posteriorment Tibald II de Bar, comte de Bar
• Joan I de Dampierre, senyor de Dampierre

Margarida ja havia estat casada amb anterioritat amb Bucard d'Avesnes, senyor Étrœungt i batlliu d'Hainaut. Per resoldre les diferències entre els fills dels dos matrimonis, el rei de França Lluís XI va donar al comtat de Flandes als Dampierre i al comtat d'Hainaut als Avesnes.
