Emperor Frederick II, who was also the ruler of Sicily, died in 1250. The Kingdom of Sicily, also known as the Regno, included the island of Sicily and southern Italy nearly as far as Rome. Pope Innocent IV claimed that the Regno had reverted to the Holy See. The Pope first offered it to Richard of Cornwall, but Richard did not want to fight against Frederick's son, Conrad IV of Germany. Then the Pope proposed to enfeoff Charles with the kingdom. Charles sought instructions from Louis IX, who forbade him to accept the offer, because he regarded Conrad as the lawful ruler. After Charles informed the Holy See on 30October 1253 that he would not accept the Regno, the Pope offered it to Edmund of Lancaster.
