Lambert I, Count of Louvain

Count Lambert "the Bearded" (c. 950 - 12 September 1015) was the first person to be described as a

In his chronicle entry for 973, Sigebert of Gembloux mentioned that Reginar and Lambert, sons of Reginar (III) Longneck, fought and killed Count Werner and his brother Rainold, who were occupying the county once held by Reginar III. They attacked at Péronnes-lez-Binche and took a fort called "Buxude" above the Haine, the river which Hainaut is named after.^[2] This was either Boussu west of Mons, or Boussoit to the east at La Louvière.^[3] Among the sources which confirm this killing, the chronicle known as the deeds (Gesta) of the bishops of Cambrai adds that the king, when he heard of this, gathered a force to besiege them, and then destroyed the castle, took them captive, and banished them from the country.^[4] The Gesta claims that Werner and Rainold had been assigned by Duke Bruno to govern Hainaut after the death of Count Richar, who had died the year before. The Gesta says that after this defeat the brothers engaged in plundering and disturbances of the peace, and then withdrew to Carolingian-ruled northern France where they improved their military practices and gained the support of Charles, Duke of Lower Lorraine, a rebellious younger brother of the French King Lothair of France, who was one of the last ruling members of the Carolingian dynasty, and Eudes, the son of his ally and kinsman Adalbert I, Count of Vermandois.

In his entry for 976 Sigebert mentioned that "the sons of Reginar Longneck" invaded Mons, this time with Charles. They fought against the counts

In Sigebert's entry for the year 977, which mentions that Charles was made Duke of Lower Lorraine at this time, Lambert and his brother Reginar IV are also mentioned.^[5] The entry notes that Lambert married Gerberga, the daughter of Charles, and his brother Reginar IV married the daughter of another French king, Hugh Capet, ancestor of the Capetian dynasty. According to the historian Ferdinand Lot, however, in 977 it was Charles who was married, and his daughter must have married later.^[6] Sigebert also mentioned that Lambert and his brother Reginar IV were relocated in the lands of their father (in terra patrum suorum relocavit). It is believed that they did not yet have full control of the counties they would eventually hold, but for example historian Jean-Louis Kupper believes that they received part.^[3]

In 978, the brothers fought on the side of France against

In 985, several records indicate an alliance between the brothers and France. Duke Charles and Reginar IV attended an assembly with King Lothar in France, and after the capture of Godfrey I of Verdun (known as "the captive") one of the conditions for his freedom was the restitution of Mons to Reginar IV. This indicates that Reginar IV still did not have control of Mons.[8]

Before 995, Lambert was engaged in on-going conflict in or near the region of the

It was only in 998, at least according to Alberic of Trois-Fontaines, that Reginar IV gained control of Mons. It is probable then, that Reginar IV did not receive Mons until after the death of his rival Godfrey "the captive", who is last recorded alive in 997.^[10] Lambert, on the other hand, was not described as a count of Leuven until 1003.^[11]

In 1006, Lambert was an ally of the powerful

According to the chronicle of the deeds (Gesta) of the bishops of Cambrai, Balderic II, who became bishop of Liège in 1008, was a kinsman of Lambert, and thought it would be good to establish friendship with him. However, the bishop of Cambrai from 1012, Gerard of Florennes, advised that he was unreliable, and was proven right by the subsequent battle of Hoegaarden. The text also claims that Gerard was influential in the appointment at this time of his own kinsman, Godfrey II "the childless" son of Godfrey the captive and enemy of Lambert, as the new Duke of Lower Lotharingia, after the 1012 death of Duke Otto, the son of Lambert's old ally Duke Charles.

In 1013 then, Lambert, with his nephew Reginar V, and

12 September 1015, at Florennes, Lambert was killed in battle. Lambert was once again supported by his nephew Reginar V. They were attacking Godfrey II and his brother Count Herman. Dietmar's report of his death described Lambert as the much hated son of Reginar, who was the worst person in his whole country, and had strangled many people in churches with bell ropes.^[14]

Legacy

After the death of Lambert, the Gesta of the bishops of Cambrai explains that bishop Gerard initially opposed the idea that, in the interests of peace, Reginar IV's son Count Reginar V should marry the daughter of count Herman, uniting the two opposed families. He argued that the couple were too closely related according to the strict papal rules of the time. (They were said to be connected in the 4th and 5th degree, although their relationship is no longer known.) However, he accepted it on advice from other bishops. The historian Michel de Waha has argued that the family only gained full legitimacy in their father's county of Hainaut after this marriage.

Many of Lambert's generation of friends and enemies died soon after, leading to a fundamental rebalancing of power that eventually favoured his family, and reduced the power of the dynasty of the Godfreys, the Verdun branch of the House of Ardenne. As recounted by Dietmar, Wichmann of Vreden was killed in 1016, thus putting Balderic, who was suspected to be involved, at odds with Emperor Henry II.^[15] Godefrey II also later defeated Gerhard in a separate battle which began as a judicial duel in 1017,^[16] capturing both Count Balderic, and Gerhard's son Siegfried. In 1018, Godfrey and Gerhard were forced to make peace by the emperor,^[17] and Balderic was also reconciled with the emperor,^[18] but Godfrey II was then crushingly defeated and captured later that year when leading imperial forces against another rebel, Dirk III, Count of Holland, whose mother, like Gerhard's wife, was a sister of the emperor's wife Cunegunde.^[19]

Despite the criticisms of the chronicles, there were many factors influencing their depiction of Lambert, including imperial politics. The chronicle of the bishops of Cambrai, in its entry for 1017, openly complains that the sisters-in-law of Emperor Henry II had been arousing rebellions against the status quo, which it associated with their bishop Gerard and his cousin Godfrey II.^[20] Apart from the balance of power in Lotharingia, another matter of dispute which influenced these alliances was the imperial succession. Henry II's successor was Conrad II, the son of Count Gerhard's sister, who Dietmar says was injured by Godfrey II's forces in 1017.

Wife and children

Lambert was the husband of Gerberga of Lower Lorraine, and father of:^[21]

• Henry I, Count of Louvain, who died without male children.
• Lambert II, Count of Louvain, also known as Balderic, was his brother's heir, and married Oda, a granddaughter of his father's old-enemy Godfrey the captive. They are ancestors of further counts of Leuven (Louvain) and Dukes of Brabant.
• Reinier (Reginar). Van Droogenbroeck has proposed his existence based on records of his grandson Baldwin of Brussels, and proposes that another grandchild is Richilde, Countess of Hainaut.
• Matilda (Maud) of Louvain, countess of Boulogne as wife of
  Eustace I of Boulogne^[22]
