About Régnier (Reginar) III, comte de Hainaut

Reginar III (c. 920 – 973) was Count of Hainaut from approximately 940 until his exile in 958.

He was the son of Reginar II, Count of Hainaut.

He took part in the rebellion of his uncle Gilbert, Duke of Lorraine. When Gilbert was killed in 939, Reginar had to pledge fealty to King Otto the Great.[citation needed]
He then allied himself with King Louis IV of France, but King Otto sent duke Hermann of Swabia to quell the rebels in 944.

Otto appointed Conrad the Red as duke of Lotharingia, who tried to diminish the power of Reginar. However, when Conrad rose against Otto, Reginar supported him. In an anarchic situation, Reginar appropriated the dowry of Gerberga of Saxony, Otto's sister and mother of the French king, and also church property.

In 957, Bruno, Archbishop of Cologne, who had also been appointed duke of Lotharingia, restored order and defeated Reginar.
As Reginar refused to submit, he was exiled to Bohemia, where he died before 973.

 He fathered two sons:

*Reginar IV, Count of Mons

  • Lambert I of Leuven


1. REGINAR [III] ([920]-973). The Annales Hanoniæ name "Raginerus" as son of "Raginerus [filius Ragineri dicti Longi-colli]"[33]. "Otto…rex" confirmed the possession of Kloster Süsteren by Prüm abbey by charter dated 1 Jun 949, signed by "Cuonradus dux, Herimannus dux, Hezzo comes, Godefridus comes, Rudolfus comes, Reginherus comes"[34]. He succeeded his father as Comte de Hainaut, although the date he took control of the county is not known. "Ragineri comitis…" signed the charter dated to [936/57] under which "Adhelardus et conjux mea Fulcuera" donated a serf to the abbey of Saint-Ghislain[35]. In 956, Reginar seized Brussels and the surrounding areas which had been the dower of Gerberge Queen of France on her first marriage to his uncle Giselbert Duke of Lotharingia. King Lothaire, together with Bruno Archbishop of Köln, invaded Count Reginar's territory, captured his fort on the Chier and took his family prisoner, releasing them only after Reginar returned the land which he had taken[36]. The Gesta Episcoporum Cameracensium records that Reginar was banished to Bohemia in [958] by Archbishop Bruno[37], but was later reinstated in Hainaut by Otto II King of Germany[38].

m ADELA, daughter of --- (-961). The Annales Hanoniæ record the death in 961 of "Adela comitissa Montensis…uxor Ragineri comitis"[39], although as this passage follows closely on those dealing with the exploits of "Raginerus Longi-colli" it is unclear to which Count Reginar the Annales are referring at this point. She is named in secondary sources as Adela von Dachsburg, daughter of Hugo [V] Graf von Dachsburg und Egisheim [Alsace] & his wife Hildegard ---, but the primary source which confirms that this is correct has not yet been identified.

 Comte Reginar [III] & his wife had two children:

Ben M. Angel note:

Original death location was mentioned as Pilsen within the present Czech Republic. However, Pilsen as a city was not founded for more than another 250 years. As such, I've removed Pilsen as the death location, and left it within the Herzogtum Bohmen (technically part of the entity that would become known as the Holy Roman Empire in the 12th century, but very much an autonomous state within the Empire).

Régnier III fut un comte de Hainaut et de 940 à 958. Il était fils de Régnier II, comte de Hainaut.
