  1. ^ Although Frederick II was crowned King of the Romans, King of Sicily, King of Jerusalem and Holy Roman Emperor, he was never crowned King of Italy at Pavia, Monza or Milan during his lifetime – see Sismondi's History of the Italian Republics in the Middle Ages, (1906), pg. 143; 147 and Kington-Oliphant's, History of Frederick the Second, Emperor of the Romans, Vol I, (1862), pg. 195 which specifically state that the Milanese refused to crown Frederick with the Iron Crown. Neither is his coronation as King of Italy mentioned in any modern source, such as Abulafia's, The New Cambridge Medieval History, Vol. V: c. 1198 – c. 1300, (1999)
