This does not mean that Novare’s detailed descriptions of duels and violent arguments were fabricated. Rather, he has described events that reflected more than caused the tensions. Yet while Edbury is right to point out that the Ibelins were not universally popular, we should not lose sight of the fact that the Ibelins retained the support of the overwhelming majority (80%) of Cypriot knights and nobles. Perhaps even more telling, they retained the affection and favor of their young lord, King Henry I of Cyprus right until his death decades later.
