Empress Matilda: Daughter and only surviving child of Henry I of England, was declared her father's heir, but her cousin Stephen usurped the throne. This led to a years long war, in which her son Henry II, was eventually declared Stephen's heir. This period is known as the Anarchy. Henry the Young King, who was crowned junior king in 1170 at the age of 15, led a revolt against his father Henry II for several months in 1173–74 and controlled much of England. Louis VIII of France: Controlled the Southeast of England and later the whole country briefly during the First Barons' War from 1215 to 1217. Edward Balliol was crowned king of Scotland in 1332 and was able to control some parts of it until 1356. His claim was recognized and supported by England.
