Frederick I of Meissen
Frederick I, called the Brave or the Bitten (1257–1323), Margrave of Meissen, was the son of Albert the Degenerate and Margaret of Sicily, grandson of Emperor Frederick II. Legend says his mother bit his cheek when she fled the Wartburg in 1270, giving him his nickname.
With his brother Diezmann he warred on their father, was captured in 1281 and reconciled in 1289. His victory over King Albert I at Lucka in 1307 secured Thuringia. Paralyzed by a stroke in 1321, he died at Eisenach in 1323.
