In 1250 the Germanic Frederick II, Holy Roman Emperor, died after having ruled Sicily for 52 years. He was King of Sicily from 1198, King of Germany from 1212, King of Italy and Holy Roman Emperor from 1220 and King of Jerusalem from 1225. His mother Constance was Queen of Sicily and his father was Henry VI of the House of Hohenstaufen. Although there is no evidence that the "triskeles" was used in Sicily in the 13th century, there is architectural evidence of its use in Austria at that time, almost certainly relating to a personal emblem of Frederick, and almost certainly stemming from his Sicilian connection.
