REGINAR [I] "Langhals/Longneck", son of [GISELBERT Graaf van Maasgau & his wife --- of Lotharingia] ([850]-Meerssen [25 Aug 915/19 Jan 916]). The primary source which confirms his parentage has not yet been identified. The Annales Hanoniæ name "Manicherius filius [Albonis]" (in a later passage clarified to be "Manicerius Registensis dominus") as "pater aut avunculus primi Ragineri" and "Raginerus dictus Longi-colli filius eius"[6], which, as explained in the Introduction, must be incorrect. The Annales Hanoniæ name "Rignerius Montensis comes" as the ally of "Francone episcopo Leodiensi" against the Vikings in 870, and in a later undated passage "Raginerus" fighting "cum Frissonibus in Walacria contra Rollonem"[7], although it is unclear from the context whether these references are to "Raginerus dictus Longi-colli". Guillaume de Jumièges describes how "Rainier au long cou duc de Hasbaigne et du Hainaut et Radbold prince de Frise" fought the Viking Rollo but were forced back to their castles[8]. The date when Reginar was installed as Comte de Hainaut is uncertain but was probably during the last quarter of the 9th century. An agreement dated 14 Jun 877 of Emperor Charles II "le Chauve", presumably written with his own death in mind, names "Arnulfus comes, Gislebertus, Letardus, Matfridus, Widricus, Gotbertus, Adalbertus, Ingelgerus, Rainerus" as those willing to support the emperor's son if he travels across the Meuse[9], although it is curious that "Giselbertus…Rainerus" should both be included if one was the father of the other. "Ragenarius comes…et coniuge mea Hersenda" confirmed the donation of revenue from "Sathanacense atque Mousense" to Saint-Dagobert de Stenay made by "Carolus…Augustus Imperiali" by charter dated to after 886[10]. The Annales Vedastini name "Balduinus…comes et Rodulfus frater eius necnon et Ragnerus" when recording that they joined Zwentibold of Lotharingia in 895[11]. The Breve Chronicon Epternacense names “Reinerus” as abbot of Echternach from 897 to 915[12]. Regino records that in 898 Zwentibold King of Lotharingia banished "Reginarium ducem…sibi fidissimum et unicum consiliarium" who went with "Odacro comite et quibusdam aliis, cum mulieribus et parvulis" to "Durfos" (near "Mosa fluvius") where they were besieged[13]. The passage appears to be the only indication that Reginar was granted the title duke. Reginar was presumably rehabilitated after King Zweintibold was murdered, as shown by the following charter. Ludwig IV "das Kind" King of Germany confirmed an exchange of property between Kloster Stablo and "Reginarius comes" by charter dated 10 Sep 902[14]. King Ludwig IV also confirmed an exchange of property involving "Reganarius comes" by charter dated 20 Oct 906[15], and a donation of property "…in pago ac in comitatu Hainuense" to the church of Tongern at the request of "Kepehardus et Reginharius comites" by charter dated 18 Jan 908[16]. "Raginarius comes" and the abbot of Stavelot granted property "in pago Hasbanio in locis Honavi, Versines et Serangio" to "quidam fidelium nostrorum Harduinus" by charter dated 911, signed by "Ragenarii comitis, Issaac comitis, Macineri comitis…"[17]. Reginar was installed as marchio by Charles III "le Simple" King of the West Franks in 915. Lay-abbot of St Servatius at Maastricht before May 898, and of Stablo and Malmédy 900-902. Richer records the death of "Ragenerus vir consularis et nobilis cognomento Collo-Longus" at "apud Marsnam palatium"[18].

m [firstly] HERSENDA, daughter of ---. "Ragenarius comes…et coniuge mea Hersenda" confirmed the donation of revenue from "Sathanacense atque Mousense" to Saint-Dagobert de Stenay made by "Carolus…Augustus Imperiali" by charter dated to after 886[19].

m [secondly] ALBERADA, daughter of ---. Her marriage is confirmed by the charter dated 10 Feb 968 under which her daughter-in-law "Gerberga…Francorum regina" donated "alodo…Marsnam in comitatu Masaugo" to Reims Saint-Rémy, confirmed by "comitibus Emmone et Ansfrido", for the souls of "senioris nostri piæ memoriæ Gisleberti suique…patris…et matris Rageneri et Albradæ"[20]. The estimated birth date of her son Giselbert suggests that Alberada may have been her husband´s second wife, assuming that the charter which names his other wife Hersenda can be dated to soon after 886 (see above). Another possibility is that both documents refer to the same person, one or other having incorrectly represented her name. Maybe heiress of Hainaut[21]. Guillaume de Jumièges describes how the wife of "Rainier au long cou" returned captured prisoners to Rollo and paid him gold, silver and all the taxes of the duchy, but does not name her[22].

Count Reginar [I] & his [second] wife had three children:

1. GISELBERT [II] ([885/900]-drowned in the Rhine, near Andernach 2 Oct 939). Richer records that "Gisleberto eius filio" succeeded on the death of "Ragenerus vir consularis et nobilis cognomento Collo-Longus"[23]. Created dux in 928 by Heinrich I King of Germany, effectively creating him GISELBERT Duke of Lotharingia.


2. REGINAR [II] ([885/900]-932 or after). The Annales Hanoniæ name "Raginerus" as son of "Raginerus dictus Longi-colli"[24]. The Miraculæ S. Maximi record that [25]. The primary source which confirms that Reginar [II] was Comte de Hainaut has not yet been identified, but this is probably correct.

Reginar I Longneck[1] (c. 850 – 915)[2] was the Duke of Lorraine from 910 until his death. He stands at the head of the clan of Reginarids, an important Lotharingian noble family.

He was the son of Gilbert, Count of the Maasgau, and a daughter of Lothair I of whom the name is not known (Hiltrude, Bertha, Irmgard, and Gisela are good candidates).

He succeeded his father in the Maasgau and was the lay abbot of Echternach between 897 and 915, of Maastricht from before May 898, and of Stablo and Malmedy between 900 and 902.

He was the Count of Mons when in 870 he and Franco, Bishop of Liège, led an army against the Vikings in Walacria. He, as Duke of Hesbaye and Hainault, and Radbold led a Frisian army with against the forces of Rollo a little later, but were forced back to his fortresses.

In an 877 capitulary from Quierzy, he appears alongside his father as one of the regents of the kingdom during Charles the Bald's absence on campaign in Italy. A Reginar appears at the Siege of Paris in 886, but this may be an uncle or nephew. The name "Reginar" or "Reginhar" (French: Régnier or Rainier) was commonplace in his family. Reginar was originally a supporter of Zwentibold in 895, but he broke with the king in 898. He and some other magnates who had been key to Zwentibold's election three years earlier then took the opportunity provided by the death of Odo of West Francia to invite Charles the Simple to become king in Lotharingia. His lands were confiscated, but he refused to give them up and entrenched himself at Durfost, downstream from Maastricht. Representatives of Charles, Zwentibold, and the Emperor Arnulf met at Sankt Goar and determined that the succession should go to Louis the Child. Zwentibold was killed by the rebels in battle in August 900.

At first, Louis appeared to be opposed to Reginar when he appointed Gebhard as his deputy in Lotharingia, but the two were never at war. In 908, Reginar recuperated the Hainault after the death of Sigard. Then, after the death of Gebhard in 910, in battle with the Magyars, Reginar appears as his successor. He led the magnates in opposing Conrad I of Germany and electing Charles the Simple their king. He was given the title marchio by Charles in 915. He never appears as the Duke of Lorraine, but he was definitely the military commander of the region under Charles. He himself was succeeded by his son Gilbert; however, the Reginarids did not succeed in establishing their supremacy in Lotharingia like the Liudolfings or Liutpoldings did in the duchies of Saxony and Bavaria.


By his wife Hersinda (or Alberada), who predeceased him, Reginar left the following children:

  • Gilbert, Duke of Lorraine
  • Reginar II, Count of Hainaut
  • Balderic, Bishop of Utrecht
  • Frederick, Archbishop of Mainz
  • a daughter, who married Berengar, Count of Namur

Balderic of Utrecht, Bishop of Utrecht, listed as child of Reginar and Hersinda above, is attached to the biography which claims that he was a cousin of Gilbert, Duke of Lorraine, and the son of different parents.

  1. His nickname is variously given in other languages as Langhals, au Long Cou, au Longue Col, Collo-Longus, or Longi-colli. Nevertheless, this nickname does not appear in primary sources and in fact refers to his eponymous grandson and great-grandson.
  2. He died at Meerssen between 25 August 915 and 19 January 916. Some sources push the latest possible death date back to 15 November 915.
