Count Rudolf, was a count in Lower Lotharingia, who apparently held possessions in Hesbaye and the nearby Maas river. He was a son of Reginar II, Count of Hainaut, and thus a member of the so-called Regnarid dynasty. There are no records which designate him clearly as count of any specific whole geographical county. Counties called Avernas and Huste were counties belonging to a count or counts named Rudolf in this period, and it has been proposed that this may have been the brother of Reginar.
Attestations
Rudolf is only clearly mentioned in two records as brother of Reginar III:
Later the brothers were clearly still powerful. Bishop Ratherius wrote his Phrenesis to defend the position he lost as Bishop of Liège, and one of his claims was that his replacement Balderic I, had benefited from nepotism, being the nephew of Counts "Regeneri atque Ruoduolti", and the son of the brother of Bishop Balderic of Utrecht.
It is generally accepted that it is the same two brothers who appear next to each other in a charter by King Otto in 949, confirming the Abbey of Susteren on the Maas to be a possession of Prüm abbey. Other charters previous to this appear to show that he held territory on the left bank of the Maas, and also the County of Avernas.
Approximately 946, a charter mentions "villa lens in comitatu avernae temporibus rodulphi comitis". Lens is the name of two neighbouring villages near the town of Avernas-le-Baudoin.
In a charter of 7 Oct 950, Kessel on the left bank of the Maas between Roermond and Venlo is described as being "in pago Masalant in comitatu Ruodolfi".
4 Jul 952. Alden-Eyck near Maaseik is described as being "in pago Huste in comitatu Ruodulphi". Huste or Hufte is generally considered to be a word derived from Hocht, in Lanaken, also on the Maas but approximately 30km southwards. Van de Weerd has proposed it was Hoeselt. Wherever it was, it must have been seat of a count.
The only other mention of both Huste and Avernas, from the same approximate period, is geographically distant from Hocht or Hoeselt, but close to Borgloon, the future seat of the county of Loon. It mentions a land-holder named Rodulf, but he is not described as a count, only a neighbour. This land exchange record, dated between 927 and 964, and probably around 950, mentioned the places, :nl:Muizen |Muizen and :nl:Buvingen|Buvingen , and Heusden being in Avernas; and Heers and :nl:Engelmanshoven|Engelmanshoven as being in a county called "Hufte", or Huste. The two groups of places are noted by Baerten, Verhelst and others as being close, but separated by the old medieval deaconry boundaries of St Truiden and Tongeren, and in the 11th century probably also the boundaries between the counties of Duras and Loon ran in a similar way.
After 958
In 958, Reginar III was defeated by King Lothair and Archbishop Bruno and banished to Bavaria. Rudolf is not explicitly mentioned in this regard, but about that same time, a Werner appears as under-advocate of the Abbey of St Truiden, a position that would in later centuries be held by the count over the area around the Abbey, an area where a Count Rudolf had been count, and a Count Werner also appears in other areas where the Reginars had been powerful. It is thought likely that Bruno replaced Rudolf as count with Werner around 958. The main documentary evidence is that in 966, a charter states that Rudolf’s property at Gelmen had been confiscated because of his infidelity and was now in the county of Werner in the pagus of Hesbaye. For all these reasons, it was argued by Léon Vanderkindere and others that Count Werner replaced Rudolf. Any wives or children that Rudolf might have had are not known from any clear records. It is known that in similar areas to Rudolf's and his brother's lordships Werner appears as count after 953. In 973 however, the sons of Reginar III, Reginar IV and his brother Lambert, returned and killed Werner and his brother Renaud. Rudolf's nephews then established themselves in the counties of Hainaut and Louvain. It was proposed by Leon Vanderkindere that the related family of Nevelong, Count of Betuwe, who married a sister of Rudolf and had a son with her named Rudolf, played a more lasting role in the Hesbaye area, both during and after the time of Werner. One Count in particular who may be a member of that family was named Eremfried, and a Count Emmo might be the same person.
A charter dated 24 Jan 966, mentions grants to the Abbey of Nivelles a Count Reginar, and a son of his called Liechard, who gave Gingelom, in Hesbaye. A Count Rudolf also appears in that charter, but he is not described as a relative and Lentlo, which he granted, is :fr:Lillois-Witterzée|Lillois south of Brussels, and not the same as Lens near Avernas.
Counts Eremfridus and Rodulfus, appear as witnesses in a grant by Bertha, the mother of a Count Arnulf, of land in Brustem to St Truiden. Bertha is thought by modern historians to be a daughter of Nevelung, thus a niece of Rudolf, and her son Count Arnulf was count of the March of Valenciennes.
Perhaps there was a final mention of Rudolf in 982, according to Jongbloed. In a charter made in Capua, 26 July 982, "on the day that we fight the Saracens" Otto II certified that if a certain "Cunradus, son of the late count Rudolf" died, he wanted his possessions in Lotharingia to go to Gorze Abbey, and these included "curtis Velm in pago Haspongowe et in comitate Eremfridi comitis". In the Battle of Cotrone itself it seems that both this Conrad, and this count Eremfried, lost their lives. Velm, now part of St Truiden, did come under Gorze Abbey, and a Count Irimfrid was recorded as dying in the battle. However, this Conrad's possessions were widespread, and on the basis of those Vanderkindere believes his father was Rodolphe Count of Ivois. Of this Count however, Vanderkindere says that given his connection to Velm it is "not without some likelihood" that he is a member of the Regnarid family, where the name Rodolphe was familiar. In the 11th century, Balderic II of Liège, brother of Gilbert the first recorded Count of Loon, was recorded as being a relative to Count Arnulf of Valenciennes, as well as the Regnarid Lambert I, Count of Louvain. In this way at least, it is clear that the later Counts of Loon were related to Rudolf.
