Prince Edmund was the son of King Henry III and Queen Eleanor of England.
In 1255 Edmund was invested ruler of the Kingdom of Sicily and Apulia by the Bishop of Rome, on behalf of Pope Innocent IV. Edmund renounced his claim to the crown of Sicily.
Suppose Edmund did not renounce his claim to the crown of Sicily. Suppose he reigns as King Edmund I of Sicily. What happens then?
