Guy II of Dampierre

Guy II de Dampierre (c. 1155–1216), son of Guillaume I de Dampierre and Ermengarde de Toucy, inherited the family lands around 1174 and held the office of constable of Champagne, as his father had before him. By marrying Mathilde I of Bourbon he became lord of Bourbon, one of France's most powerful barons.

He joined the Third Crusade at the Siege of Acre and fought at Arsuf, and later fought for Philip Augustus in the conquest of Normandy and at Bouvines in 1214. He died on 18 January 1216, leaving Bourbon to his son Archambaud and Dampierre to Guillaume.
