On 06 Apr 1199 King Richard "Lionheart" I of England (age 41) was besieging Châlus Chabrol Castle, Domfront. During the course of the evening King Richard "Lionheart" I of England (age 41) was shot by a crossbow. The wound quickly became gangrenous; Richard died in the arms of his mother Eleanor of Aquitaine Queen Consort Franks and England (age 77). His brother King John "Lackland" of England (age 32) succeeded I King England.

There was a brother between Richard and John named Geoffrey Duke of Brittany who had a son Arthur (age 12), who was around twelve, and a daughter Eleanor (age 15), who was around fifteen, whose mother was Constance Penthièvre Duchess Brittany (age 38).

King Philip II of France (age 33) had planned for Eleanor (age 15) to marry his son, probably to bring Brittany into the French Royal family, possibly to pursue a claim on England.

King Philip II of France (age 33) supported Arthur's (age 12) claim to the English throne. In the resulting war Arthur (age 12) was captured, imprisoned and never seen again. Eleanor (age 15) was captured, probably around the same time as Arthur, and imprisoned, more or less, for the remainder of her life, even after King John's death through the reign of King Henry III since she represented a threat to Henry's succession.
