Frederick II, Holy Roman Emperor

Frederick II Hohenstaufen ruled the Holy Roman Empire from 1211 through 1250. His empire was frequently at war with the Papal States, so it is not surprising the he was excommunicated - in fact, twice. Pope Gregory IX went so far as to call him the anti-Christ and after his death the idea of his second coming where he would rule a 1000 year Reich took hold, possibly in part because of this.

He was born on December 26, 1196; initially he was King of Sicily, from age four. His kingdom was held for him by Pope Innocent III until he was of age.

Otto of Brunswick had been elected Holy Roman Emperor in 1209; Frederick had been elected emperor by a rebellious faction who had the backing of Innocent III in 1211 at the Diet of Nuremberg, but until the debacle at the battle of Bouvines in 1214 this was an empty honor. After Bouvines Otto was deposed (to die in 1218), Innocent III managed to get most of the princes to renounce the excommunicated Otto and elect Frederick.

Said to be literate in 9 languages, Frederick was a very modern ruler for his times, being a patron of science and learning, and having fairly advanced views on economics. He abolished state monopolies, internal tolls, and import regulations within his empire.

He was known in his own time as the Stupor mundi, the "Wonder of the world". Frederick wrote a manual on the art of falconry, De arte venandi cum avibus ("On the art of hunting with birds"), of which many illustrated copies survive from the 13th and 14th centuries.

Frederick's Crusade ended in a truce and coronation of Frederick as King of Jerusalem on March 18, 1229.
