Bertha, duchess of Lorraine

Bertha of Lorraine (or Bertha of Swabia) (b.c. 1123/30 – d. 1194/5) was a member of the Hohenstaufen dynasty. She was the daughter of Frederick II, Duke of Swabia and, through marriage to Matthias I duke of Lorraine, she was duchess of Lorraine (c.1138-1176).

Family

Bertha (sometimes called Judith) was the daughter of Frederick II, Duke of Swabia and Judith of Bavaria (1103- 22 February 1131), daughter of Henry IX, Duke of Bavaria. Through her father, Bertha was a member of the Hohenstaufen dynasty: her paternal uncle was king Conrad III and her brother was the future emperor Frederick Barbarossa. Bertha married Matthias of Lorraine c.1138. Bertha frequently issued charters alongside her husband. She used at least two different types of seal to authenticate her documents, on which she was riding astride on horseback, which was a highly unusual image for a medieval noblewoman to use. After the death of Matthias in 1176, Bertha issued documents with her son, Simon, who succeeded his father as duke of Lorraine.

Marriage and issue

With Matthias I, Bertha had several children, including:

• Simon (died 1205), his successor in Lorraine
• Frederick (died 1206), count of Bitche and his nephew's successor
• Judith (died 1173), married Stephen II, count of Auxonne (1170)
• Alice (died 1200), married Hugh III, Duke of Burgundy
• Theoderic (died 1181), bishop of Metz (1174–1179)
• Matthias (died 1208), count of Toul
• Unnamed daughter who died young
