Frederick II, Holy Roman Emperor

Frederick II (December 26, 1194 –  December 13, 1250), of the Hohenstaufen dynasty, was a pretender to the title of King of the Romans from 1212 and unopposed holder of that monarchy from 1215. As such, he was King of Germany, of Italy, and of Burgundy. He was Holy Roman Emperor from his papal coronation in 1220 until his death. His original title was King of Sicily, which he held as Frederick I from 1198 to his death. His other royal titles, accrued for a brief period of his life, were King of Cyprus and Jerusalem by virtue of marriage and his connection with the Crusades.
