The couple had two children, and Sanchia died in 1261. The displeasure of the English nobility with King Henry III ultimately resulted in a civil war, the Second Barons’ War (1264–1267). The leader of the forces against Henry was his brother-in-law, Simon de Montfort, 6th Earl of Leicester, who was married to Henry’s sister Eleanor. Richard was a supporter of his brother during the Second Barons’ War. He was taken prisoner at the Battle of Lewes and imprisoned until his nephew, the future King Edward I, led the royalists into battle again, defeating and killing de Montfort at the Battle of Evesham in 1265. 60-year-old Richard made a third marriage to 15-year-old Beatrice of Falkenburg in1269.

For the first child of King Henry VII of England, the first Tudor monarch, the name Arthur was chosen in hopes that he would bring a new Arthurian age to the new Tudor dynasty. Sadly, that was not to be. Within months of their marriage, Arthur and Catherine of Aragon became ill, probably of the sweating sickness.  Catherine survived, but she was left a widow as Arthur did not survive. Henry VII and his wife, Elizabeth of York, were naturally distraught at the death of their eldest son. Their second son succeeded his father as King Henry VIII in 1509, leaving us to ask the question, “What if Arthur had become king?”
