The House of Balliol (de Bailleul) was a Picard and Anglo-Norman family originating from Bailleul who began to rule some estates in England in the reign of William Rufus. In the late 13th and 14th centuries, two members of the house were kings of Scotland.
Both Balliols had English support for their claims; both were deposed. Edward died without issue, but the Balliol descent continued through his cousin Christine de Lindsay (granddaughter of John II), who married Enguerrand V, Lord of Coucy, to the lords of Coucy and ultimately the Bourbon kings of France and Spain.
