Frederick III of Sicily

Frederick II (or III) (13 December 1272 – 25 June 1337) was the regent of the Kingdom of Sicily from 1291 until 1295 and subsequently King of Sicily from 1295 until his death. He was the third son of Peter III of Aragon and served in the War of the Sicilian Vespers on behalf of his father and brothers, Alfonso ΙΙΙ and James ΙΙ. He was confirmed as king by the Peace of Caltabellotta in 1302. His reign saw important constitutional reforms: the Constitutiones regales, Capitula alia, and Ordinationes generales. Name Although the second Frederick of Sicily, he chose to call himself "Frederick III" (being one of the rare medieval monarchs who actually used a regnal number) – presumably because only some fifty years before, his well-known and remembered great-grandfather had ruled Sicily and also used an official ordinal: Fridericus secundus, imperator etc.. Thus, Fridericus tertius was better in line with the precedent of his ancestor's ordinal. However, an anecdote attributes Frederick's choice of numeral to him being the third son of Peter. The next man called Frederick to occupy the Sicilian throne was dubbed by later generations of historians as Frederick III: Frederick III the Simple, though he himself did not use an ordinal.
