Matthias I, Duke of Lorraine (born 1119)
Matthias I, Duke of Lorraine
Matthias I was the duke of Lorraine from 1138 to his death as the eldest son and successor of Simon I and Adelaide. Like his forefathers going back to Theodoric II and even to Adalbert, he was a stern supporter of the king of Germany and Holy Roman Emperor. He married Bertha, daughter of Frederick II, Duke of Swabia, and therefore niece of the Hohenstaufen king Conrad III and sister of Frederick Barbarossa, future emperor.
