File:Siège d’Acre.png

Siege of Acre

Theobald I (French: Thibaut or Thibauld de Bar) (born c. 1158 – died 13 February 1214) was Count of Bar from 1190 until his death, and a Count of Luxembourg from 1197 until his death. He was the son of Reginald II of Bar and his wife Agnès de Champagne. He became count when his brother, Henry, was killed in the siege of Acre.

After his third marriage, he sought to reclaim his wife's lands of Luxembourg, Durbuy and Laroche with the approval of Philip of Swabia. Theobald therefore besieged the castle at Namur, whereupon a conference was held in which Philip of Namur and his brother Baldwin renounced the disputed territories of Luxembourg, Durbuy and Laroche. The Treaty of Dinant signed 6 July 1199 at Saint Medard, later made it official.

During the Albigensian Crusade, Theobald led an army to reinforce Simon de Montfort at the Template:Ill in June 1211.

After his death in 1214, his eldest son Henry II, from his second marriage, succeeded him as count. His eldest daughter Agnes, from his first marriage, married Frederick II, Duke of Lorraine. His lands in Luxembourg reverted to Waleran III of Limburg, who married Theobald's widow Ermesinde of Namur. Theobald was buried at St. Mihiel.

Marriage

Theobald I was married three times. In 1176, he married Laurette of Loon (de Looz), daughter of Louis I, Count of Loon, and Agnes of Metz; they had one daughter. Secondly, he married Ermensinde de Bar-sur-Seine, daughter of Guy of Bar-sur-Seine and Petronille de Chacenay, circa 1189. They had one son and two daughters, although Theobald and Ermensinde divorced circa 1195. He then married Ermesinde of Luxembourg, daughter of Henry IV "the Blind" of Luxembourg and Agnes of Guelders, in 1197. They had two sons and three daughters.
