William II of Dampierre

(1196 - 3 Sep 1231)

According to Wikipedia:

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.[1]

His brother, Archambaud VIII, inherited Bourbon, and William inherited Dampierre. He married Margaret II, Countess of Flanders and Hainault,[1] in 1223 and was thus regent of Flanders until his death as "Willem I" (or "Guillaume Ier"). In 1226 William and Margaret founded a Cistercian nunnery at Saint-Dizier.[2] Their sons William III and John continued to confirm and patronize the nunnery during their lives,[2] including William II's burial there in 1231.[2] William and Margaret founded more Cisterian nunneries throughout the county of Flanders, including Flines Abbey.[2]

He had four children (three sons) by Margaret and the eldest took part in the War of the Succession of Flanders and Hainault:

William III, Count of Flanders and Lord of Kortrijk[2]
Guy, Count of Flanders and Margrave of Namur
John I, Lord of Dampierre, Viscount of Troyes, and Constable of Champagne[2]
Joanna, married in 1239 to Hugh III of Rethel,[3] then in 1243 to Theobald II of Bar[3]
