The other piece of business the king concluded while in Gascony had to do with Sicily. Considered a rich prize at the time, the island was up for grabs following the death of Henry’s other brother-in-law Frederick in 1250. As the emperor of the Germans and King of the Romans, Frederick II had been at war with a succession of popes for possession of southern Italy and Sicily. Henry had originally bargained on an alliance with Frederick as a way of forcing Louis to give back Normandy. He married his younger sister Isabella to the twice-widowed older man, promising him 30,000 marks to boot, but nothing came of this strategy except another Henry (born to Isabella, who later died in childbirth). Frederick’s older sons Conrad and Manfred, also from previous alliances, were ready to carry on the fight with Pope Innocent IV, who by that time was desperate for anyone to rid him of these infernal Germans. Henry looked like an easy target. His desire for Normandy was common knowledge and Sicily had once been a Norman possession. Still, he was uneasy about waging war on his nephew and namesake. Then both the younger man and Conrad died in 1254, and Henry took the papal bait.
