Notes
or of St. Germain Montgomery, Normandy
https://en.wikipedia.org/wiki/Arnulf_de_Montgomery
Arnulf de Montgomery (born c.1066; died 1118×1122) was an Anglo-Norman magnate.
[note 1] He was a younger son of Roger de Montgomery and Mabel de Bellême. 
Arnulf's father was a leading magnate in Normandy and England, and played an active 
part in the Anglo-Norman invasion of southwestern Wales in the late eleventh century. 
Following the Montgomery's successes against the Welsh, Arnulf established himself 
at Pembroke, where a earth and timber castle was erected, and was likely rewarded 
with the title Earl of Pembroke.

At the turn of the twelfth century Arnulf reached height, with his lordship including 
much of the former Welsh Kingdom of Deheubarth as well as various lands in 
Yorkshire. Not long after reaching this apex of his career, Arnulf assisted his eldest 
surviving brother, Robert de Bellême, in a rebellion against Henry I, King of England. 
It was also about this time that Arnulf married a daughter of Muirchertach Ua Briain, 
King of Munster, in what appears to have been an effort to gain military support 
against the English Crown. Following the ultimate collapse of the rebellion, however, 
the Montgomerys were outlawed and banished from the realm, and Arnulf appears to 
have spent much of the next twenty-odd years in a peripatetic life in Ireland and 
Normandy. Arnulf's career exemplifies the opportunities available to younger sons of 
the Anglo-Norman aristocracy. Arnulf appears to have died between 1118 and 1122. 
He is not known to have left any descendants, and the family's surname appears to 
have died with him.
Background[edit]

Arnulf was likely born in the late 1060s,[7] possibly about 1066.[8] He was a younger 
son of Roger de Montgomery, Vicomte of the Hièmois (died 1094) and Mabel de 
Bellême (died 1077).[9] Arnulf's parents likely married in about 1050.[10] His mother 
was a daughter of, and eventual heiress of, William de Bellême, Lord of Alençon (died 
c.1063).[9] Arnulf's father, an apparent kinsman and close companion of William II, 
Duke of Normandy (died 1087), was an eminent magnate in Normandy.[11] As tutor to 
Matilda, Duchess of Normandy (died 1083), Roger and his eldest sons did not embark 
on the 1066 Norman invasion of England. When William returned to Normandy as king 
in 1067, Roger accompanied him back to England, and was granted extensive lands, 
including the Sussex rapes of Arundel and Chichester, followed by the county of 
Shropshire.[10] Soon afterwards, Roger was made Earl of Shrewsbury. By 1086, he 
was one of the wealthiest tenants-in-chief in England.[12] Arnulf makes his first 
appearance in the historical record at about this time when he and his elder brother, 
Roger de Poitou (died before 1140), witnessed William's confirmation of their father's 
grant to the Norman abbey of Troarn in 1082/1083.[13][note 2]

In 1088, Roger and at least three of his sons participated in plot to eject William 
Rufus, King of England (died 1100) from the throne with the intent to replace him with 
Robert Curthose, Duke of Normandy (died 1134), William Rufus' elder brother.[15] This 
rebellion is documented by several sources, such as the ninth–twelfth-century Anglo-
Saxon Chronicle,[16] and the twelfth-century texts Chronicon ex chronicis,[17] Gesta 
regum Anglorum,[18] and Historia Anglorum.[19] According to the "E" version of the 
Anglo-Saxon Chronicle—the only strictly contemporary source of the four—Robert 
Curthose's followers captured Odo, Bishop of Bayeux (died 1097) and thereby gained 
control of the castle of Rochester. This source identifies several leading members of 
the insurrection, including three unnamed sons of Roger.[20] Whilst it is possible that 
these brothers were Roger's eldest sons Robert de Bellême (died 1130×), Hugh de 
Montgomery (died 1098), and Roger de Poitou,[21] it is not impossible that the latter 
took no part in the rising, and that the third brother was in fact Arnulf himself.[22] 
Although the rebellion was an ultimate failure, the king imposed no penalty upon 
Roger, and allowed Roger de Poitou to be reinstated with most of the lands that the 
eleventh-century Domesday Book shows he previously held.[23]

Rise[edit]
Arnulf's father was one of three close supporters of the king who were settled along 
the Anglo-Welsh border, in a region known as the Welsh marches. Although the first 
real penetration of Anglo-Norman power occurred in the 1070s, it wasn't until the last 
decade of the eleventh century that more permanent marcher settlements were 
envisaged in Wales.[27] In 1093, encroaching marcher lords engaged and slew Rhys 
ap Tewdwr, King of Deheubarth in Brycheiniog.[28] Contemporaries marked Rhys' fall 
as the end of kingship amongst the Welsh,[29] and his demise left a power-vacuum in 
which men such as Arnulf seized upon.[30] The south-west Welsh gwladoedd 
("countries")[31] of Ceredigion and Dyfed were thus overwhelmed and settled by the 
conquering incomers.[29] In the latter gwlad ("country"),[32] Arnulf's father founded 
an earth and timber castle in which Arnulf established himself.[33] This ringwork,[34] 
strategically seated on the highest point of a promontory between two tidal inlets, sat 
on the site where the castle of Pembroke stands today. Although nothing now remains 
of the original castle,[35] it is described by the twelfth–thirteenth-century Itinerarium 
Kambriæ as a "slender fortress built of stakes and turf".[36]

William Rufus subsequently rewarded Arnulf with a lordship seated at his castle.[37] 
There is substantial evidence indicating that Arnulf was, in fact, made Earl of 
Pembroke.[38] For example, he was accorded forms of the Latin style comes by 
Anselm, Archbishop of Canterbury (died 1109),[39] Itinerarium Kambriæ,[40] the 
twelfth-century Vita Anselmi,[41] the twelfth-century Historia ecclesiastica,[42] the 
thirteenth/fourteenth-century Brut y Tywysogyon,[43] the twelfth-century Warenne 
Chronicle,[44] and the cartulary of the abbey of Saint-Martin de Sées.[45] The castle 
at Pembroke is remarkable in the fact that, unlike other Anglo-Norman or English 
fortresses in west Wales, it never fell into the hands of the Welsh.[46] At some time 
between 1097 and 1108, Arnulf's castellan at Pembroke, Gerald de Windsor (died 
1116×1136), married Rhys' daughter, Nest (died c.1130).[47] According to Brut y 
Tywysogyon, Arnulf captured and imprisoned Rhys' young son, Hywel, before the latter 
was able to escape after suffering certain bodily injuries.[48] Having established 
himself at Pembroke, Arnulf appears to have resided in England, leaving Gerald at 
Pembroke as his de facto custos or steward.[49][note 4]

On his father's death in 1094, Arnulf's elder brother, Hugh de Montgomery, inherited 
the earldom of Shrewsbury. Surviving sources reveal that the brothers were closely 
associated with each other.[52] Within two years they made a joint grant to the far-off 
abbey of La Sauve-Majeure.[53][note 5] Furthermore, Arnulf appears to have 
witnessed a grant of Hugh de Montgomery's dapfier to the abbey, in a charter dated to 
1095–1098.[55] In a Latin grant to the abbey of Saint-Martin de Sées,[52] founded by 
his father,[56] Arnulf bestowed a donation on behalf of his ancestors, lord, friends, 
and "very dear brother Hugh" ("carissimi fratris sui Hugonis").[57][note 6] Although 
the particular wording in this grant may reveal genuine affection for his brother,[52] 
these acta as a whole could reveal that Arnulf was regarded as the heir of the 
unmarried and childless Hugh de Montgomery,[59] and that William Rufus intended to 
acknowledge this inheritance as well.[52]

Partly as a result of the political conquest of Wales in the late eleventh century, the 
Anglo-Norman Church endeavoured to subjugate and exploit the Welsh Church. From 
the perspective of the English Crown, the Welsh Church was isolated, archaic, 
deviant, and backward-looking. Conversely, Anglo-Normans regarded themselves as 
religious reformers, and sought to impose their own standards and practices upon the 
Welsh. One way in which the Anglo-Normans imposed their ecclesiastical authority 
upon the Welsh was through the appointment and control of bishops.[62] Within a 
year of his consecration as Archbishop of Canterbury in December 1093, Anselm 
temporarily suspended the Welsh bishops of Glamorgan and St David's, revealing that 
these diocesan territories had fallen under Canterbury's ecclesiastical authority.[63]
[note 7] In May 1095, Wilfrid, Bishop of St David's (died 1115) came to terms with 
Anselm.[66] In turn, the latter admonished several leading Anglo-Normans holding 
lands in the diocese of St David's, urging them to regard Wilfrid as their bishop, and to 
return the lands, tithes, and churches that they had unjustly seized from him. Two 
marcher lords specifically singled out by Anselm were Arnulf and Robert de Bellême.
[67][note 8] In fact, the ravaging of the lands of St Davids in 1097 by Arnulf's steward 
at Pembroke, Gerald, is recorded by the thirteenth/fourteenth-century Brenhinedd y 
Saesson, Brut y Tywysogyon, the "B" and "C" versions of the eleventh–thirteenth-
century Annales Cambriæ.[69] As a friend of the archbishop, Arnulf may have been 
more liable to respect this call of restraint from Anselm than from anyone else.[70]

In 1098, together with Hugh d'Avranches, Earl of Chester (died 1101), Hugh de 
Montgomery led a summer invasion of Gwynedd. Although the Anglo-Normans easily 
defeated the Welsh defenders, the attackers were later overwhelmed on Anglesey in 
an encounter with the forces of Magnús Óláfsson, King of Norway (died 1103).[71] 
Arnulf appears to have learned of his brother's fate about a month later in Normandy, 
since he travelled to Sées, and founded a priory of the abbey's monks at Pembroke in 
dedication to the memory of Hugh de Montgomery and his father.[72] Although Arnulf 
may well have hoped to inherit his brother's title and lands, William Rufus granted 
them to Arnulf's older brother Robert de Bellême,[73] who had captured Helias de la 
Flèche, Count of Maine (died 1110) only months before, dutifully handing the count 
over to the king.[74][note 9]

Downfall[edit]

At the turn of the twelfth century, the Montgomerys were one of the leading families in 
England. At this point, Robert de Bellême had reached the height of his power,[77] 
and appears to have been the most powerful and prosperous magnate in the Anglo-
Norman world.[78] Besides inheriting the expansive continental lands of the 
Montgomery and Bellême families, and succeeding to the earldom of Shrewsbury and 
the rape of Arundel, Robert de Bellême also obtained the honour of Tickhill in 
Nottinghamshire and southern Yorkshire. Furthermore, by right of his wife's 
inheritance, Robert de Bellême gained the small but important continental county of 
Ponthieu.[79] His brother, Roger de Poitou, was one of the most powerful magnates in 
northwest England,[80] holding lands in Lancashire, Nottinghamshire, Essex, 
Yorkshire, and Suffolk. By right of his wife, he gained the continental county of La 
Marche.[81][note 10] As for their brother, Arnulf, he likely held the Earldom of 
Pembroke, a lordship which appears to have constituted the core of the former 
Kingdom of Deheubarth.[83] Arnulf gained the lordship of Holderness, following the 
downfall of its former lord, the disgraced Odo, Count of Champagne (died after 1115–
1118).[84][note 11]

In August 1100, whilst Robert Curthose was absent en route from the Holy Land, the 
reigning William Rufus was killed, and the vacant English throne was seized by their 
younger brother, Henry, Count of the Cotentin (died 1135).[80] Fearing an invasion 
from Normandy by Robert Curthose, an early act of Henry's reign was an alliance with 
Robert II, Count of Flanders (died 1111), formalised by treaty in March 1101.[94] One 
of the guarantors recorded lending surety for the English king was Arnulf himself.[95] 
Guarantors to such acts often led negotiations between involved parties, which could 
indicate that Arnulf acted as an intermediary between the king and count.[94] 
Although his involvement on Henry's behalf further evidences Arnulf's considerable 
status, his career in the king's service was short-lived.[8]

Although Robert de Bellême had initially accepted Henry as king,[96] by the time 
Robert Curthose asserted his claim to the throne at Alton in 1101, Robert de Bellême 
was supporting the duke's cause.[80] According to Historia ecclesiastica, the king 
spent a year collecting evidence against Robert de Bellême; and in 1102, Henry 
summoned the latter, charging him with forty-five different offences against himself 
and Robert Curthose.[97] According to Brut y Tywysogyon, Arnulf was likewise 
summoned and charged.[98] Arnulf appears to have fled to Wales,[99] and Historia 
ecclesiastica records that Robert de Bellême fortified his English castles against 
Henry's men.[100] Whilst Robert de Bellême made alliances with the Welsh,[80] Arnulf 
reached out to the Irish.[101] Specifically, Brut y Tywysogyon reveals that Arnulf sent 
Gerald to Ireland in order to arrange military assistance from Muirchertach Ua Briain, 
King of Munster (died 1119).[102] The alliance was formalised by a remarkable 
marriage between Arnulf and one of Muirchertach's daughters, the record of which is 
preserved by Historia ecclesiastica,[103] Brut y Tywysogyon,[104] and alluded to by 
the eleventh–fourteenth-century Annals of Inisfallen.[105] These sources are further 
corroborated by a particular letter from Muirchertach to Anselm,[106]—perhaps dating to 
about 1105[107] or 1106/1107,[108]—in which Muirchertach expressed his gratitude to 
the archbishop for intervening with Henry on behalf of "my son-in-law Arnulf".[106] 
Although the native Gaelic form of the bride's name is unknown for certain,[109] 
Historia ecclesiastica names her "Lafracoth" in Latin.[110] One possibility is that her 
name represents Aifric.[111] Another is that it represents Lebarcam.[112]

What specifically motivated Muirchertach to agree to an alliance is unknown. It 
certainly brought him into close contact with one of Europe's leading families.[114] 
One possibility is that he was attempting to enhance his status on an international 
stage.[115] He may have also sought to secure the valuable trade route from south 
Wales and the Bristol Channel to Waterford.[116][note 12] His involvement may well 
have formed part of a larger plan to not only increase power in Ireland but further 
exert influence throughout the Irish Sea region.[117][note 13] As for Arnulf, the marital 
alliance could have been undertaken in an attempt to enhance his own status in 
society.[119][note 14] On the other hand, the marriage may have been a path by 
which Arnulf or his brother attempted to gain access to Muirchertach's military might.
[122] Furthermore, the alliance may have been coordinated as a means to enlist 
assistance from the overseas forces of Muirchertach's powerful ally, Magnús.[123] 
Certainly, Historia ecclesiastica states that Henry was greatly concerned with Magnús' 
presence in the region, although there is no evidence that the Norwegians assisted 
the rebels.[124][note 15] Despite the fact that Brut y Tywysogyon reports that 
Muirchertach lent the two brothers military support,[128] and the distinct possibility 
that Roger de Poitou aided them as well,[129] the Bellême-Montgomery insurrection 
ended in utter failure.[130]
Surviving sources give differing accounts of the rebellion.[132] Arnulf's principal 
contribution appears to have been his participation in a predatory strike into 
Staffordshire.[133] According to the twelfth-century Historia regum Anglorum and 
Chronicon ex chronicis, Robert de Bellême and Arnulf, supported by Welsh allies, 
ravaged a part of the county, before carrying off livestock and men to Wales.[134] 
The detailed account of the general uprising preserved by Historia ecclesiastica 
appears to be the most reliable record of events. This source reveals that, following 
Robert de Bellême's flight from the king's summons, Henry appears to have raised a 
feudal host consisting of his tenants-in-chief (who owed him knight-service) and the 
old English fyrd (a levy of one armed man from about every five hides or six 
carucates).[135] Historia ecclesiastica states that Henry's host besieged the castle of 
Arundel for three months before it's capitulation, after which the king led his forces to 
the castle of Tickhill which immediately surrendered.[136] After temporarily standing 
down his army, Henry resumed operations in the autumn, he is recorded to have 
seized the castle of Bridgnorth after a three-week siege. At about this point, William 
Pantulf (died 1112?), a former vassal of the Montgomerys, is stated to have offered his 
services to Robert de Bellême. Upon being rebuffed by the latter, William Pantulf is 
recorded to have gone over to Henry's side, and was apparently instrumental in 
convincing Robert de Bellême's Welsh allies desert him and support the king instead.
[137][note 16] Brut y Tywysogyon specifically states that Iorwerth ap Bleddyn (died 
1111), a leading Welshman, was bought off by the king and began to harry his former 
ally's lands.[139] After Henry's forces marched to Shrewsbury itself, Historia 
ecclesiastica records that Robert de Bellême's submitted to the king in person.[140] 
Defeated, the three surviving sons of Roger de Montgomery were banished from the 
kingdom, with their lands and titles declared forfeit.[141][note 17]

Aftermath[edit]

Whilst Robert fled to the continent, surviving sources suggest that Arnulf—and likely 
others from the ill-fated insurrection—sought refuge in Ireland.[147] Certainly, Gesta 
regum Anglorum makes note of a deterioration in relations between Muirchertach and 
Henry before an English trade embargo forced reconciliation upon the Irish.[148] One 
possibility is that this episode occurred as a consequence Muirchertach's part in the 
rebellion.[149][note 18] Furthermore, Historia ecclesiastica claims that Arnulf and 
other Normans assisted the Muirchertach in a military capacity, apparently against the 
forces of Magnús himself. However, after the latter fell in battle against Muirchertach's 
forces, this source states that the Irish turned upon the Normans, and that 
Muirchertach forced Arnulf from Ireland altogether.[153] In fact, the details of this 
account are likely erroneous, as Magnús appears to have fallen against the Ulaid, not 
Muirchertach's men.[154][note 19] The claim of Arnulf's flight from Ireland, and 
Muirchertach's enmity against him, may be mistaken as well, especially in light of the 
emphatic letter between Muirchertach and Anselm concerning Arnulf.[156] 
Nevertheless, the account preserved by Historia ecclesiastica may be evidence of 
English mercenarial involvement in Ireland during Henry's reign.[157][note 20] In fact, 
it is possible that Arnulf did indeed campaign in Ireland on behalf of Muirchertach, and 
that the latter's marital alliances with Magnús and Arnulf in 1102 were undertaken in 
the context of offsetting Muirchertach's main rival, Domnall Mac Lochlainn, King of 
Cenél nEógain (died 1121).[159] Unfortunately for Muirchertach, not only was Magnús 
slain in a skirmish in the following year,[160] but Muirchertach's forces suffered a 
disastrous defeat at the hands of Domnall's forces at Mag Coba.[161][note 21] If there 
is any truth to the claim of Arnulf being driven from Ireland, it is possible that Historia 
ecclesiastica may evince an attempt by Muirchertach to mend fractured relations with 
Henry.[163]

Robert Curthose initially agreed to support Henry against the banished Robert de 
Bellême, who was now in Normandy and hostile to the duke.[165] At some point before 
June 1103, Arnulf appears to have betrayed his brother's trust, since Historia 
ecclesiastica states that Arnulf took the castle of Alménêches, a Montgomery family 
stronghold, and handed it over to the duke.[166] It may have been at this point that 
Arnulf sought refuge in Ireland.[167] Whatever the case, Robert de Bellême's efforts 
to recover the castle led to his razing of the nearby nunnery of Alménêches, where his 
sister, Emma (died 1113), was abbess.[80] By 1104, his military successes against the 
duke forced the latter to come to terms. With Robert de Bellême and Robert Curthose 
thus reconciled, Henry turned against the two and finally defeated them in battle, near 
the castle of Tinchebray in September 1106.[168] Although a version of Brut y 
Tywysogyon suggests that Arnulf took part in the battle, the account of Arnulf's earlier 
betrayal at Alménêches preserved by Historia ecclesiastica may contradict this.[169] 
Despite the correspondence evidencing Anselm's reconciliation of Henry with Arnulf, 
the latter never held land in England ever again,[170] and appears to have endured a 
peripatetic career for about twenty years.[171] Evidence that he visited England, at 
least on one occasion, may be preserved by Vita Anselmi which states that Arnulf 
made a returning voyage from Normandy ("de Normannia Angliam rediens").[172][note 
22]


Between 1110 and 1112, Robert de Bellême involved himself in uprisings in southern 
Normandy, encouraged by Henry's opponent, the recently inaugurated Foulques, 
Count of Anjou and Maine (died 1143). Henry responded by bringing charges against 
Robert de Bellême, and finally seizing him in November 1112. The latter's lands were 
declared forfeit, and he was imprisoned by the king for the rest of his life.[80] During 
the first quarter of the twelfth century, Arnulf attested eight charters of Foulques, 
making Arnulf one of the count's most frequent witnesses.[178] In about 1114, Arnulf 
witnessed an act between his great-niece, Philippa, Countess of Poitou, and 
Bernard-Aton, Vicomte of Béziers.[179] Arnulf's influence at Foulques's court appears 
to be evidenced by particular actions in 1118.[8] That year the townsfolk of Alençon 
rebelled against Henry and their lord Stephen, Count of Mortain (died 1154),[180] 
whilst the latter were campaigning against a continental coalition attempting to 
replace the king with Robert Curthose's illegitimate son, William Clito (died 1128).
[181][note 23] The region of Alençon was a former power centre of the Bellême family, 
and according to Historia ecclesiastica, the townsfolk requested that Arnulf intervene 
with Foulques on their behalf against Stephen's injustices and oppression.[183] In 
what turned out to be Henry's single greatest defeat,[184] Foulques' troops then 
seized the town and besieged the citadel, before crushing Henry's relief forces, after 
which Foulques secured the citadel once and for all.[185] Arnulf, probably now in his 
fifties, is not noted in any of the surviving sources documenting the clash.[186] 
Nevertheless, he and his family could well have been responsible for an uprising that 
appears to flared up at about the same time in former Montgomery-Bellême lands in 
central Normandy. This insurrection seems to have contributed to Henry's restoration 
of much of the former Montgomery-Bellême lands in Normandy to Robert de Bellême's 
son, William III, Count of Ponthieu (died 1171), in June 1119.[187]

The next certain record concerning Arnulf occurs in 1122, when his name is listed in a 
mortuary roll, circulated after the death of churchman Vitalis of Savigny (died 1122), in 
which the nuns of the abbey of Alménêches commemorated him, his parents, and his 
younger brother Philip (died 1099).[189][note 24] Arnulf, therefore, died sometime 
between 1118 and 1122.[191] The depiction of Arnulf's death preserved by Historia 
ecclesiastica is likely unhistorical.[186] This account relates that, following Magnús' 
death, Arnulf was forced from Ireland by Muirchertach, only to return about twenty 
years later, whereupon he remarried the latter's daughter, and died following the 
feast.[192] There is no evidence that Arnulf left any descendants.[193][note 25]

Legacy[edit]

There are numerous instances where contemporaries noted members of the 
Montgomery family for unusual cruelty—Robert de Bellême in particular.[199] According 
to Historia ecclesiastica, Mabel was murdered by a vassal, a particular act that may 
evidence her unpleasantness.[200][note 26] Historia ecclesiastica describes Hugh de 
Montgomery as the only "mild and loveable" (mansuetus et amabilis) of Mabel's sons,
[202] whilst Welsh sources present him in a much more negative light.[203] A source 
concerning Arnulf may be Planctus Ricemarch, a sorrowful Latin lament composed by 
scholar Rhygyfarch ap Sulien (died 1099). This source—a contemporary composition 
bewailing the cultural upheaval and oppression inflicted upon the Welsh after the 
Anglo-Norman conquests of 1093—may refer to subjugation suffered under Arnulf and 
his father.[204]

The actions of the Montgomery family illustrate the remarkable speed at which Norman 
families could spread across far-flung regions. Although Norman families tended to 
practice primogeniture, the conquest of England and the opening up of Britain 
contributed a new area of exploitation for landless younger sons of the aristocracy.
[205] The careers of younger sons of the Anglo-Norman aristocracy are often obscure, 
with few surviving sources documenting their activities. The younger sons of Roger de 
Montgomery and Mabel are an exception,[94] and Arnulf's career illustrates the 
various opportunities available to contemporaries of his rank—men who could not rely 
upon inheritance alone, and who had to acquire territories of their own.[206] Despite 
losing his lands later in his career, Arnulf's numerous and regular attestations in court 
circles reveal that he retained substantial personal prestige. The far-flung nature of 
these attestations may well indicate that his skills as a negotiator were well-known 
and valued. Indeed, Arnulf's career reveals the importance of personal-connections in 
the courtly-world of the Anglo-Norman era.[207]

Arnulf's family—traced with certainty only two patrilineal generations previous[208]—
derived its surname from lands now known as Sainte-Foy-de-Montgommery and Saint-
Germain-de-Montgommery, in Calvados, Normandy.[209] Although descendants of 
Arnulf's siblings survived for several generations, the family's toponymic surname died 
with Arnulf.[210]
