Question: What nationality is Constance Of Aragon, Queen Of Sicily's husband?
Sentence (from "Frederick the Simple"): "Frederick the Simple" is often confused with an earlier Sicilian monarch, his grandfather Frederick II, who chose to call himself "Frederick III" even though he was actually only the second King Frederick to occupy the Sicilian throne; his self-appellation was retained by later generations of genealogists and historians.
