Pepin III, Count of Vermandois
Pepin III, Count of Vermandois( also known as Pepin II, Count of Senlis; French:" Pépin")( c. 846 – 893) was a Frankish noble; the Count of Senlis and Count of Vermandois( 850 – 893); Lord of Valois( 877 – 886), and later Count of Valois( 886 – 893).
He was a son of Pepin, Count of Vermandois and Valois and thus a grandson of Bernard of Italy, who was himself a grandson of Charlemagne.
The brothers of Pepin III were Herbert I, Count of Vermandois and Bernard II, Count of Laon.
Pepin III of Vermandois's wife is unknown; their son was:
Diederik of Heinsberg, Count of Loon
Diederik of Heinsberg
( French:" Thierry", German:" Dietrich", English:" Theodoric")( died between 17 and 21 January 1361), Count of Loon( French:" Looz") and Count of Chiny( 1336- 1361), was the son of Godfrey II, Lord of Heinsberg( son of Diederik, Lord of Heinsberg, and Joanna of Leuven), and Matilda( daughter of Arnold V, Count of Loon and Chiny, and Marguerite Vianden).
In 1336, Diederik's uncle Louis IV, Count of Loon and Chiny, died without having had children, and a succession crises emerged.
An agreement of 1190 stipulated that if the House of Loon were extinguished, the county would then be integrated with the Principality of Liège.
The reaction of the Chapter of Saint- Lambert was immediate.
The Prince- Bishop of Liège Adolph of La Marck moved to incorporate the County of Loon into the principality, while Diederik maneuvered to assume the title of count.
However, since Diederik had married Adolph ’s sister and the bishop was fond of their son, family relations won out.
Until his death in 1344, the prelate used all of his influence to ensure that the county remained in possession of his brother- in- law.
But the death of the bishop did not terminate possession the Counties of Loon and Chiny by the Heinsbergs, because Adolph ’s nephew Engelbert III succeeded him as Prince- Bishop of Liège.
Engelbert removed the threat of excommunication pronounced against Diederik and allowed him to remain at the head of the counties until his death.
In 1336, Diederik married Kunigunde of the Mark,( d. 1343), daughter of Engelbert I, Count of the Mark, and Kunigonde of Blieskastel, sister of Adolph of the Marck and Eberhard II, Count of the Mark( also his uncle through marriage to Matilda ’s sister Marie).
Diederik and Kunigunde had one son: Upon his death in 1361, Diederik ’s nephew and heir, Godfrey of Heinsberg, Lord of Daelenbroeck, claimed the counties of Loon and Chiny, while the Prince- Bishopric of Liège claimed it as fief of the church.
Gerard, Count of Loon
Count Gerard( or Gerhard) of Loon( died 1191), was son and successor of Louis I, Count of Loon, and Agnes of Metz.
Because of a widespread misunderstanding concerning a document from 1101, some generations earlier, he is often wrongly referred to as the second Gerard in this dynasty," Gerard II".
Gerard became count in difficult times.
His father Louis, who ravaged the territory of Sint- Truiden, was attacked and beaten near Brustem on July 28, 1171, by the citizens of this city assisted by Gilles, Count of Duras.
They then besieging the castle of Loon, killing Count Louis on 11 August.
The assault against the fortress was prevented by the arrival of reinforcements of Louis ’ son-in- law Godfrey III, Count of Louvain, and a truce was concluded.
Gerard and his mother went to emperor Frederick Barbarossa in Aachen to obtain compensation, but the citizenry of Sint- Truiden successfully defended their claim.
Falling ill, he fulfilled a vow to go make a pilgrimage to Jerusalem.
On his return, he found the county in full disorder.
His brother Hugo had begun to fortify the village of Brustem, which had caused strife for many years.
Finally in 1175, he granted the inhabitants of Brusthem the laws and freedom enjoyed by the citizens of Liege.
He went to war against Rudolf of Zähringen, Prince- Bishop of Liège.
On July 31, 1180, he and his knights routed the episcopal army in Tongeren, plundering and burning the cathedral.
In retaliation, Rudolf burned the castle and the town of Loon, as well as the village and the Abbey of Munsterbilzen and the castle at Montenaeken.
Several villages and sixteen churches were completely destroyed.
Gerard sued for peace through the mediation of Henry the Blind, Count of Luxembourg, and Engelbert I, Count of Berg.
Gerard moved his court to Kuringen, near the Belgian city of Hasselt located in the Flemish Region in the province of Limburg, and in 1182, he founded the Abbey of Herkenrode, entrusted to the Cistercian Order.
He built a heptagonal" donjon" at Rieneck, inspired" donjon" of Borgloon.
Gerard joined the Third Crusade led by emperor Frederick Barbarossa, King Philip Augustus of France and the English King Richard the Lionheart.
He was killed on 2 November 1191 at the headquarters of Saint- Jean d'Acre.
His body was returned to Loon and buried at Herkenrode, where he rests alongside his wife and children.
In 1135, Gerard married Adelaide of Gelderland, daughter of Henry I, Count of Guelders, and Agnes of Arnstein, daughter of Louis III of Arnstein.
Gérard and Adelaide had at least eight children:
Gerard was succeeded as Count of Looz by his son Louis upon his death.
