Queen of Germany in the context of "Gisela of Swabia"

The House of Habsburg-Lorraine (German: Haus Habsburg-Lothringen) originated from the marriage in 1736 of Francis III, Duke of Lorraine and Bar, and Maria Theresa of Austria, later successively Queen of Bohemia, Queen of Hungary, Queen of Germany, Queen of Croatia and Archduchess of Austria, etc. etc. Its members form the legitimate surviving line of both the House of Habsburg and the House of Lorraine, and they inherited their patrimonial possessions from the female line of the House of Habsburg and from the male line of the House of Lorraine.

The House of Lorraine's branch of Vaudémont and Guise became the main branch after a brief interlude in 1453–1473, when the duchy passed in right of Charles de Bourbon's daughter to her husband, John of Calabria, a Capetian. Lorraine reverted to the House of Vaudémont, a junior branch of the House of Lorraine, in the person of René II, who later added to his titles that of Duke of Bar.

Agnes of Poitou (c. 1025 – 14 December 1077) was the queen of Germany from 1043 and empress of the Holy Roman Empire from 1046 until 1056 as the wife of Emperor Henry III. From 1056 to 1061, she ruled the Holy Roman Empire as regent during the minority of their son Henry IV.

After the death of her husband, she proved an inexperienced regent unable to effectively assert her power and secure loyal allies. In Germany, she is still remembered as a sympathetic historical figure, even if a flawed politician.

Matilda of Ringelheim (c. 892 – 14 March 968), also known as Saint Matilda, was a Saxon noblewoman who became queen of Germany. Her husband, Henry the Fowler, was the first king from the Ottonian dynasty, and their eldest son, Otto the Great, restored the Holy Roman Empire in 962. Matilda founded several spiritual institutions and women's convents. She was considered to be extremely pious, righteous and charitable. Matilda's two hagiographical biographies and The Deeds of the Saxons serve as authoritative sources about her life and work.

Margaret of Brabant (4 October 1276 – 14 December 1311), was the daughter of John I, Duke of Brabant and Margaret of Flanders. She was the wife of Henry, Count of Luxembourg, and after his election as King of Germany in 1308, she became Queen of Germany.
