4. King Henry II of England and Eleanor of Aquitaine were John's parents. Which French king was his mother's husband before King Henry II, who later complicated John's war with France on a personal level?
From Quiz King of England: Life and Reign of King John
Answer:
Louis VII
In 1137, Eleanor of Aquitaine and Louis VII were married in Bordeaux, at the Cathedral of Saint-André. The marriage was an unhappy one, fraught with disagreements, Louis' annoyance at Eleanor interfering in matters of state, and the lack of a male heir, with the marriage only producing two daughters. In 1152, they met at a castle in Beaugency to annul their marriage, about to do so because they were third cousins once removed, sharing a common ancestor of Robert II of France. John was very close to his mother, and heard all about Eleanor of Aquitaine's grievances and claims of mistreatment by Louis VII. Eleanor's scathing portrait of Louis certainly made it easy for John to go to war with his family.
When Louis VII died in 1180, he was succeeded by his son Philip II, who Louis had had with his third wife, Adela of Champagne. Philip never forgot what he heard about Eleanor of Aquitaine's treatment of his father, spurring a personal motive against Eleanor and her family, as well as a political one. Eleanor of Aquitaine supported John as King of England without question. Like John hearing of Louis VII's misgivings, Philip II had been painted a scathing portrait of John and his mother, making any war with them much easier to fight and less likely to be open to diplomatic negotiations (and vice versa).
