Richard I, known as Richard Cœur de Lion or Richard the Lionheart because of his reputation as a great military leader and warrior, was King of England from 1189 until his death in 1199. He also ruled as Duke of Normandy, Aquitaine, and Gascony; Lord of Cyprus; 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 Henry II of England and Eleanor of Aquitaine and was therefore not expected to become king, but his two elder brothers predeceased their father.

Eleanor of Aquitaine was Duchess of Aquitaine in her own right from 1137 to 1204, Queen of France from 1137 to 1152 as the wife of King Louis VII, and Queen of England from 1154 to 1189 as the wife of King Henry II. As the heiress of the House of Poitiers, which controlled much of southwestern France, she was one of the wealthiest and most powerful women in Western Europe during the High Middle Ages. Militarily, she was a leading figure in the Second Crusade, and in a revolt in favour of her son. Culturally, she was a patron of poets such as Wace, Benoît de Sainte-Maure, and Bernart de Ventadorn, and of the arts of the High Middle Ages.
