Qui es va casar amb Gertrude of Flanders, Duchess of Lorraine?

Gertrude of Flanders (c. 1070–1117), was a Countess of Louvain and Landgravine of Brabant by marriage to Henry III, Count of Leuven, and a Duchess of Lorraine by marriage to Theodoric II, Duke of Lorraine. At the time the duchy was the upper Lorraine, since 959 separated from the duchy of Lower Lorraine.

Enric III de Lovaina (mort a Tournai el febrer o març de 1095) va ser comte de Lovaina i Brussel·les de 1078 a 1095. Ell era el fill d'Enric II, comte de Lovaina i Brussel·les, i Adela, possible hereva del comtat de Teisterbant.

Estava aliat a la majoria dels senyors veïns: era cunyat del comte Balduí II d'Hainaut i gendre del comte de Flandes Robert I el Frisó; d'altra banda el bisbe de Lieja, Enric I de Verdun, era un prelat pacífic. Sense por de les invasions estrangeres, va poder dedicar-se a l'administració dels seus dominis.

Va afavorir diverses institucions religioses a l'oest dels comtats i els va concedir privilegis (1086 Abadia d'Affligem). Fou un notable legislador i va sanejar les terres mitjançant l'eliminació del bandidatge.

Després de la mort d'Herman II, comte palatí de Lotaríngia (20 de setembre de 1085), va rebre el landgraviat de Brabant (que era un feu imperial entre el Dender i el Sena). El juliol de 1095, va participar en un torneig organitzat pel castellà de Tournai. Va ser ferit mortalment en una llança de justes contra el cavaller Gosuin de Forest.

Theodoric II (died 30 December 1115), called the Valiant, was the Duke of Lorraine from 1070 to his death. He was the son and successor of Gerhard and Hedwige of Namur. He is sometimes numbered Theodoric I if the Dukes of the House of Ardennes, who ruled in Upper Lorraine from 959 to 1033, are ignored in favour of the dukes of Lower Lorraine as predecessors of the later Dukes of Lorraine.

In fact, Sophia, the daughter of Duke Frederick II of the House of Ardennes, who had inherited the counties of Bar and Montbéliard, had a husband named Louis, who contested the succession. In order to receive the support of his brother, Theodoric gave his brother the County of Vaudémont and convened an assembly of nobles, who elected him duke over Louis. Soon Louis was dead, but his son, Theodoric II of Bar, claimed the succession anyway. However, Emperor Henry IV confirmed Theodoric the Valiant in the duchy. Probably, for this reason, Theodoric remained faithful to the emperors throughout his rule. He fought the Saxons while they were at war with the Emperor between 1070 and 1078 and he generally opposed the popes Gregory VII and Urban II when they were in conflict with the Emperor.

In 1095, he planned to take up the Cross (i.e., go on Crusade, specifically the First), but his ill health provoked him to drop out, nevertheless convincing his barons to go east. Thereafter, he took little part in imperial affairs, preferring not to intervene between Henry IV and his son Henry, or against Lothair of Supplinburg, duke of Saxony.
