Edward II, also known as Edward of Caernarfon or Caernarvon, was King of England from 1307 until he was deposed in January 1327. The fourth son of Edward I, Edward became the heir to the throne following the death of his older brother Alphonso. Beginning in 1300, Edward accompanied his father on campaigns in Scotland, and in 1306 he was knighted in a grand ceremony at Westminster Abbey. Edward succeeded to the throne the next year, following his father's death. In 1308, he married Isabella of France, the daughter of the powerful King Philip IV, as part of a long-running effort to resolve the tensions between the English and French crowns.

Edward I, also known as Edward Longshanks and the Hammer of the Scots, was King of England from 1272 to 1307. Concurrently, he was Lord of Ireland, and from 1254 to 1306 he ruled Gascony as Duke of Aquitaine in his capacity as a vassal of the French king. Before his accession to the throne, he was commonly referred to as the Lord Edward. The eldest son of Henry III, Edward was involved from an early age in the political intrigues of his father's reign. In 1259, he briefly sided with a baronial reform movement, supporting the Provisions of Oxford. After reconciliation with his father, he remained loyal throughout the subsequent armed conflict, known as the Second Barons' War. After the Battle of Lewes, Edward was held hostage by the rebellious barons, but escaped after a few months and defeated the baronial leader Simon de Montfort at the Battle of Evesham in 1265. Within two years, the rebellion was extinguished and, with England pacified, Edward left to join the Ninth Crusade to the Holy Land in 1270. He was on his way home in 1272 when he was informed of his father's death. Making a slow return, he reached England in 1274 and was crowned at Westminster Abbey.
