The boy was married as a child to Marguerite of France (1158–1197), daughter of the French King Louis VII. The intention was political, but it did not work. War came between Henry II and Louis. Henry joined in rebellions directed at his father. A civil war (1173/74) occurred in which Young Henry and his mother, with Scots and French support, fought against Henry II. The king won, just. Young Henry died ten years later, of dysentery. As he died before his father he never achieved power.
