Richard I was King of England from 1189 until his death in 1199. He also ruled as Duke of Normandy, Aquitaine and Gascony, Lord of Cyprus, and Count of Poitiers, Anjou, Maine, and Nantes, and was overlord of Brittany at various times during the same period. He was the third of five sons of King Henry II of England and Eleanor of Aquitaine and seemed unlikely to become king, but all his brothers except the youngest, John, predeceased their father. Richard is known as Richard Cœur de Lion or Richard the Lionheart because of his reputation as a great military leader and warrior. The troubadour Bertran de Born also called him Richard Oc-e-Non, possibly from a reputation for terseness.
