Etymology

According to John Koch and several other historians, the Latin name "Venedotia" from whence the Welsh name "Gwynedd" comes is derived from the Irish word "Feni", referring at one time to a specific group on the island and later broadening to become a general reference to the Irish people as a whole, the free, nonslave people in particular. The Irish, especially the Laighin, are known to have colonized and/or conquered much of northern Wales in the mid-4th to early 5th centuries.

Alternatively, the name Gwynedd may derive from Brythonic Ueneda, which may be akin to Goidelic (ancestor of Irish) Fenia (which gives fiana, "war-band" in Old Irish - e.g. Finn and his warriors). Thus the possible meaning may be "Land of the Hosts" or "Land of the Warrior Bands".

After Cadwallon, Gwynedd appears to have held a pre-eminent position amongst the petty Cambrian states in the post-Roman period.

During the later 9th century and 10th century the coastal areas of Gwynedd, particularly Môn, were coming under increasing attack by Viking raiders. These raids no doubt had a seriously debilitating effect on the country but fortunately for Gwynedd the victims of the Vikings were not confined to Wales.

The brothers raided Meirionydd with the Lord of Powys as important there as he was in the Perfeddwlad. However it would not be until 1136 that the cantref was firmly within Gwynedd's control. Perhaps because of their support of Earl Hugh of Chester, Gwynedd's rival, in 1124 Cadwallon slew the three rulers of Dyffryn Clwyd, his maternal uncles, bringing the cantref firmly under Gwynedd's vassalage that year.

. Cadwaladr, Gruffydd's youngest son, inherited the commote of Aberffraw on Ynys Môn, and the recently conquered Meirionydd and northern Ceredigion, that is Ceredigion between the rivers Aeron and the Dyfi.

By 1141 Cadwaladr and Madog ap Maredudd of Powys led a Welsh vanguard as an ally of the Earl of Chester in the Battle of Lincoln
Battle of Lincoln (1141)
The Battle of Lincoln or First Battle of Lincoln occurred on 2 February 1141. In it Stephen of England was captured, imprisoned and effectively deposed while Empress Matilda ruled for a short time.-Account:...

, and joined in the route which made Stephen of England prisoner of Empress Matilda for a year. Owain, however, did not participate in the battle, keeping the majority of Gwynedd's army at home. Owain, of restrained and prudent temperament, may have judged that the aiding in Stephen's capture would lead to the restoration of Matilda and a strong royal government in England; a government which would support Marcher lords, support hitherto bereft since Stephen's usurpation.

Owain and Cadwaladr came to blows in 1143 when Cadwaladr was implicated in the murder of Prince Anarawd ap Gruffydd of Deheubarth, Owain's ally and future son-in-law, on the eve of Anarawd's wedding to Owain's daughter. Owain followed a diplomatic policy of binding other Welsh rulers to Gwynedd through dynastic marriages, and Cadwaladr's border dispute and murder of Anarawd threatened Owain's efforts and credibility. As ruler of Gwynedd, Owain stripped Cadwaladr of his lands, with Owain's son Hywel

 dispatched to Ceredigion, where he burned Cadwaladr's castle at Aberystwyth. Cadwaladr fled to Ireland and hired a Norse fleet from Dublin, bringing the fleet to Abermenai to compel Owain to reinstate him. Taking advantage of the brotherly strife, and perhaps with the tacit understanding of Cadwaladr, the marcher lords mounted incursions into Wales. Realizing the wider ramifications of the war before him, Owain and Cadwaladr came to terms and reconciled, with Cadwaladr restored to his lands. Peace between the brothers held until 1147, when an unrecorded event occurred which led Owain's sons Hywel and Cynan

By now, Owain's enemies had joined Henry II's camp, enemies such as his wayward brother Cadwaladr and in particular the support of Madog of Powys.

 rescued the king. Henry II retreated and made his way back to his main army, by now slowly advancing towards Rhuddlan. Not wishing to engage the Norman army directly, Owain repositioned himself first at St. Asaph, then further west, clearing the road for Henry II to enter into Rhuddlan "ingloriously". Once in Rhuddlan Henry II received word that his naval expedition had failed, as instead of meeting Henry II at Degannwy or Rhuddlan, it had gone to plunder Môn.

In a later letter to the Byzantine Emperor, Henry probably recalled these experiences when he wrote of the Welsh:

A people called Welsh, so bold and ferocious that, when unarmed, they do not fear to encounter an armed force, being ready to shed their blood in defence of their country, and to sacrifice their lives for renown.http://www.britannia.com/wales/lit/lit6.html


The naval expedition was led by Henry II's maternal uncle (Empress Matilda's half-brother), Henry FitzRoy
Henry FitzRoy (d. 1158)
Henry FitzRoy was an illegitimate son of Henry I of England by Nest, daughter of Rhys ap Tewdwr, last king of Deheubarth , and his wife, Gwladys ferch Rhiwallon ap Cynfyn. He held lands from his royal father in Narberth and Pebidiog...

; and when they landed on Môn, Henry FitzRoy had the churches of Llanbedr Goch and Llanfair Mathafarn Eithaf torched. During the night the men of Môn gathered together, and the next morning fought and defeated the Norman army, with Henry FitzRoy falling under a shower of lances. The defeat of his navy and his own military difficulties had convinced Henry II that he had "gone as far as was practical that year" in his effort to subject Owain, and the King offered terms to the prince.

Owain I of Gwynedd, "ever prudent and sagacious", recognized that he needed time to further consolidate power, and agreed to the terms. Owain was to render homage and fealty to the King, and resign Tegeingle and Rhuddlan to Chester, and restore Cadwaladr to his possessions in Gwynedd.

The death of Madog ap Meredudd of Powys in 1160 opened an opportunity for Owain I of Gwynedd to further press Gwynedd's influence at the expense of Powys. However, Owain continued to further Gwynedd's expansion without rousing the English crown, maintaining his 'prudent policy' of Quieta non movere (don't move settled things), as Lloyd wrote. It was a policy of outward conciliation, while masking his own consolidation of authority. To further demonstrate his good-will, in 1160 Owain handed over to the English crown the fugative Einion Clud. By 1162 Owain was in possession of the Powys cantref of Cyfeiliog, and its castle of Tafolwern; and ravaged another Powys cantref of Arwystli
Arwystli
Arwystli was a cantref in medieval Wales, located in the headland of the River Severn in what is now the county of Powys.

, slaying its lord, Hywel ab Ieuaf. Owain's strategy was in sharp contrast to Rhys ap Gruffydd, prince of Deheubarth, who in 1162 rose in open revolt against the Normans in south Wales, drawing Henry II back to England from the continent.

In 1163 Henry II quarrelled with Thomas Becket, the Archbishop of Canterbury

, causing growing divisions between the king's supporters and the archbishop's supporters. With discontent mounting in England, Owain I of Gwynedd joined with Rhys ap Gruffydd of Deheubarth in a second grand Welsh revolt against Henry II. England's king, who only the prior year had pardoned Rhys ap Gruffydd for his 1162 revolt, assembled a vast host against the allied Welsh, with troops drawn from all over the Angevin empire assembling in Shrewsbury, and with the Norse of Dublin paid to harass the Welsh coast. While his army gathered on the Welsh frontier, Henry II left for the continent to negotiate a truce with France and Flanders to not disturb his peace while campaigning in Wales.

However, when Henry II returned to England he found that the war had already begun, with Owain's son Dafydd raiding Angevin positions in Tegeingle, exposing the castles of Rhuddlan and Basingwerk to "serious dangers", wrote Lloyd. Henry II rushed to north Wales for a few days to shore up defences there, before returning to his main army now gathering in Oswestery.

The vast host gathered before the allied Welsh principalities represented the largest army yet assembled for their conquest, a circumstance which further drew the Welsh allies into a closer confederacy, wrote Lloyd. With Owain I of Gwynedd the over all battle commander, and with his brother Cadwaladr as his second, Owain assembled the Welsh host at Corwen in the vale of Edeyrion where he could best resist Henry II's advance.

The Angevin army advanced from Oswestry into Wales crossing the mountains towards Mur Castell, and found itself in the thick forest of the Ceiriog Valley

 where they were forced into a narrow thin line. Owain I had positioned a band of skirmishers in the thick woods overlooking the pass, which harassed the exposed army from a secured position. Henry II ordered the clearing of the woods on either side to widen the passage through the valley, and to lessen the exposure of his army. The road his army travelled later became known as the Ffordd y Saeson, the English Road, and leads through heath and bog towards the Dee. In a dry summer the moors may have been passable, however "on this occasion the skies put on their most wintry aspect; and the rain fell in torrents [...] flooding the mountain meadows" until the great Angevin encampment became a "morass

," wrote Lloyd. In the face of "hurricane" force wind and rain, diminishing provisions and an exposed supply line stretching through hostile country subject to enemy raids, and with a demoralized army, Henry II was forced into a complete retreat without even a semblance of a victory.

In frustration, Henry II had twenty-two Welsh hostages mutilated; the sons of Owain' supporters and allies, including two of Owain's own sons. In addition to his failed campaign in Wales, Henry's mercenary Norse navy, which he had hired to harass the Welsh coast, turned out to be too few for use, and were disbanded without engagement.

Henry II's Welsh campaign was a complete failure, with the king abandoning all plans for the conquest of Wales, returning to his court in Anjou and not returning to England for another four years. Lloyd wrote;

It later came to light that Hywel Trwyndwn (the bodyguard and brother to Iorweth) was not allowed to claim his inheritance due to his undesirable nose. this was then passed down the lineage through Thomas Davies, of Peniarth Fawr, to his yonges and most ferocious daughter Lyn "the Twrch deuar" Brasssington.

It is true that [Henry II] did not cross swords with [Owain I], but the elements had done their work for [the Welsh]; the stars in their courses had fought against the pride of England and humbled it to the very dust. To conquer a land which was defended, not merely by the arms of its valiant and audacious sons, but also by tangled woods and impassable bogs, by piercing winds and pitiless storms of rain, seemed a hopeless task, and Henry resolved to no longer attempt it.


Owain expanded his international diplomatic offensive against Henry II by sending an embassy to Louis VII of France

 in 1168, led by Arthur of Bardsey, Bishop of Bangor (1166–1177), who was charged with negotiating a joint alliance against Henry II. With Henry II distracted by his widening quarrel with Thomas Becket, Owain's army recovered Tegeingle for Gwynedd by 1169.

Like his father before him, Owain I promoted stability in upper Gwynedd as no foreign army was able to campaign past the Conwy, marking nearly 70 years of peace in upper Gwynedd and on Ynys Môn.

In his later reign Owain I was the styled princeps Wallensium, Latin for the Prince of the Welsh, a title of substance given his leadership of the Welsh and victory against the English king, wrote historian Dr. John Davies. Additionally, Owain I commissioned the Life of Gruffydd ap Cynan, the biography of his father in which Owain firmly asserted his primacy over other Welsh rulers by "absolute right through decent" from Rhodri the Great, according to Davies.

Civil war and usurpation 1170–1195

, had both drawn considerable strength from family connections they had maintained across the Irish Sea in Dublin, and it was these connections which had restored Gruffydd on several occasions to his throne and had provided his father, Cynan, with a place of refuge during the usurpations of the 11th Century. It is therefore possible that Owain hoped to maintain this Irish connection by ensuring the succession of one of his sons born of this Irish woman, Pyfog. Furthermore, it seems illogical - given the fact Owain was so set on their succession and the respect he no doubt commanded in Ireland - that the mother of Rhun and Hywel was a mere commoner and that both those children were born out of wedlock. What the annals record, however, is that in 1146 the eldest son and designated heir, Rhun - a man who was acclaimed as a great warrior - "died" mysteriously, and that Hywel his natural brother was proclaimed the new Edling

Hywel ab Owain Gwynedd Wales Prince of Gwynedd in 1170, a Welsh poet and military leader. Hywel was the son of Owain Gwynedd, prince of Gwynedd, and an Irishwoman named Pyfog. In recognition of this, he was also known as Hywel ap Gwyddeles...

 duly succeeded his father in 1170 and the realm was plunged immediately into a civil war that appears to have been a conflict between two rival factions; one which was pro-Irish and seeking to ensure the succession of Hywel and protect the legacy of Owain Gwynedd and his father, and a second which seems to be an anti-Irish coalition and headed by Iorwerth Drwyndwn
Iorwerth Drwyndwn
Iorwerth ab Owain Gwynedd , meaning "the broken-nosed", was the eldest legitimate son of Owain Gwynedd and his first wife Gwladys ferch Llywarch. He married Marared ferch Madog. His son Llywelyn the Great eventually united the realm and became known as Llywelyn Fawr and is one of Wales's most...

 and Owain's widow, Cristin ferch Goronwy ab Owain.

They made their move, and within a few months of his succession Hywel was overthrown and killed at the Battle of Pentraeth in 1171. It seems that Iorwerth was injured badly enough to be ruled out of the succession (he was to die in 1174), leaving Dafydd as the leading figure in this cabal, which included his brother Rhodri as well as his half brother Maelgwn ab Owain Gwynedd
Maelgwn ab Owain Gwynedd
Maelgwn ab Owain Gwynedd was a prince of part of Gwynedd.Maelgwn was the son of Owain Gwynedd and Gwladus ferch Llywarch ap Trahaearn, and therefore full brother to Iorwerth Drwyndwn, the father of Llywelyn the Great...

 and the nephews of another half brother Cynan ab Owain, namely Gruffudd ap Cynan and Maredudd ap Cynan.

Although the exact division of the spoils is unclear, Maelgwn appears to have gained Anglesey whilst the sons of Cynan held the cantrefs of Meirionydd, Eifionydd and Ardudwy between them. However Dafydd appears at to have been recognised as pre-eminent amongst them and was regarded in some way as the overall leader. Naturally, once he'd enjoyed some of the benefits of power, Dafydd felt disinclined to share, as well as no doubt nervous that he might also soon share the fate of his predecessor Hywel; in 1173 he acted against his brother Maelgwn and drove him into exile in Ireland thereby gaining possession of all Anglesey for himself.

The following year he expelled all his remaining family rivals and made himself master of all Gwynedd and in 1175 "seized through treachery" his brother Rhodri and imprisoned him for good measure. Thus Dafydd re-united all Gwynedd under his one rule and in order to strengthen his position he sought an agreement with Henry II

. Secure in his now truncated realm, Dafydd now appears to have pushed ambition to one side and resolved to enjoy the quiet life. There is no record of him engaging in any further strife for the twenty years or so after the settlement of 1175. Dafydd may not have inherited the leadership abilities of his father but he had sufficient qualities of diplomacy and tact remaining to ensure he could live at peace with his neighbours. This appears to be the one quality recognised by his contemporaries as he was described by Giraldus Cambrensis

Llywelyn the Great

See also Llywelyn ap Iorwerth

Llywelyn, later known as Llywelyn the Great, was sole ruler of Gwynedd by 1200, and made a treaty with King John of England the same year. Llywelyn's relations with John remained good for the next ten years. He married John's illegitimate daughter Joan, also known as Joanna, in 1205, and when John arrested Gwenwynwyn ab Owain

 of Powys in 1208 Llywelyn took the opportunity to annex southern Powys. In 1210 relations deteriorated and John invaded Gwynedd in 1211. Llywelyn was forced to seek terms and to give up all his lands east of the River Conwy, but was able to recover these lands the following year in alliance with the other Welsh princes. He allied himself with the barons who forced John to sign Magna Carta in 1215. By 1216 he was the dominant power in Wales, holding a council at Aberdyfi that year to apportion lands to the other princes.

Following King John's death, Llywelyn concluded the Treaty of Worcester with his successor Henry III in 1218. During the next fifteen years Llywelyn was frequently involved in fighting with Marcher lords and sometimes with the king, but also made alliances with several of the major powers in the Marches. The Peace of Middle in 1234 marked the end of Llywelyn's military career as the agreed truce of two years was extended year by year for the remainder of his reign.

Llywelyn the Great was determined to enforce the right of legitimate sons in Welsh succession law to bring Gwynedd in line with other Christian countries in Europe. However, by promoting his younger son Dafydd he was up against considerable support for his elder son Gruffydd from traditionalists in Gwynedd. However, with Gruffydd a prisoner the support for Gruffydd could not be transformed into anything more dangerous. Although Dafydd lost one of his most important supporters when his mother died in 1237, he retained the support of Ednyfed Fychan, the Seneschal of Gwynedd and the wielder of great political influence. Llywelyn suffered a paralytic stroke in 1237, and Dafydd took an increasing role in government. Dafydd ruled Gwynedd following his father's death in 1240.

Dafydd ap Llywelyn

Although King Henry III of England had accepted Dafydd's claim to rule Gwynedd, he was not disposed to allow him to retain his father's conquests outside Gwynedd. In 1241 the King invaded Gwynedd, and Dafydd was forced to submit in late August. Under the terms of the Treaty of Gwerneigron
Treaty of Gwerneigron
Treaty of Gwerneigron was a peace treaty signed by Henry III, king of England and Dafydd ap Llywelyn, prince of Wales of the House of Gwynedd, on 29 August 1241. The treaty brought to an end Henry's invasion of Wales begun earlier that month....

, he had to give up all his lands outside Gwynedd, and also to hand over to the King his half brother Gruffydd whom he had been keeping a prisoner. Henry thereby gained what could have been a useful weapon against Dafydd, with the possibility of setting Gruffydd up as a rival to Dafydd in Gwynedd, but Gruffydd died trying to escape from the Tower of London by climbing down a knotted sheet, and fell to his death in March 1244.

With his main rival dead Dafydd formed an alliance with other Welsh rulers and began a campaign against the English occupation of parts of Wales. After savage fighting the campaign was successful until Dafydd's sudden natural death brought it to a halt. At the time of his death he had no children and with Gruffydd dead the succession would pass to the sons of Gruffydd. The only adult sons of Gruffydd were Owain Goch ap Gruffydd
Owain Goch ap Gruffydd

 who divided the realm between them.

Llywelyn ap Gruffydd

Llywelyn was in Gwynedd at the time of his elevation to the throne and had fought alongside his uncle Dafydd during the last campaign of his reign. This gave him an advantage over his elder brother Owain who had been imprisoned in England with his uncle since 1242. Owain returned to Gwynedd - he apparently "escaped" or was released from Chester immediately after the news of Dafydd's death reached England. Llywelyn and Owain were able to come to agreement and the reduced territory of Gwynedd were divided between them.

In 1255 their younger sibling Dafydd ap Gruffydd reached maturity and Henry III sensing an opportunity to create mischief demanded that he be allowed his division of Gwynedd also. Llywelyn rejected this on the grounds that this would further weaken the realm and play into England's hands. Dafydd formed an alliance with Owain and at the Battle of Bryn Derwin

 met Llywelyn in battle. Llywelyn was victorious and imprisoned Owain and confiscated his lands. He also imprisoned Dafydd for a short period before coming to terms with him.

Between 1255 and 1258 Llywelyn orchestrated a campaign against England across all of Wales gaining allies in Deheubarth and Powys. By 1258 he was acknowledged by almost all the native rulers as Prince of Wales

. In 1263 his brother Dafydd defected to England for reasons which are unclear. It has been speculated that the death of their mother may have had an effect.

 in 1267 and the title "Prince of Wales" was recognised by the King of England. All the native Welsh princes were to be vassals of Llywelyn and it is from this point that the independent history of the kingdom of Gwynedd comes to an end.

The principality of Wales was to be a short-lived creation. As is explained in greater detail elsewhere, the relationship between England and Wales broke down following the death of Henry III in 1272. By 1276 Llywelyn had been declared a rebel by the new King Edward I who was determined to be the master of the whole island of Great Britain

 came to North Wales to mediate between Llywelyn ap Gruffudd and Edward Longshanks. Llywelyn ap Gruffudd was offered a bribe: one thousand pounds a year and an estate in England, if he would surrender his control (which extended at least to Gwynedd and Deheubarth) to Edward. Llywelyn wrote rejecting the offer . Within a month, Llywelyn, on 11 December 1282, was killed at Cilmeri in an ambush. His leaderless forces were routed shortly afterwards and the English forces led by Edward I moved to occupy Powys and eastern Gwynedd.

. As the situation deteriorated it seems most likely that Dafydd and his family hoped to remain at Y Bere just long enough to avoid the worst of the Welsh winter before they were compelled to evacuate the site at the end of March in advance of the English forces who were manoeuvering to place it under siege. From this point forwards the prince, his family and the remains of his government were fugitives sleeping outdoors, forced to keep moving from place to place to avoid capture. Castell Y Bere's starving garrison would eventually surrender on April 25. After the fall of Y Bere, Dafydd's movements are speculative but he is recorded in May 1283 leading raids from the mountains supported to the bitter end by Goronwy ap Heilin, Hywel ap Rhys and his brother Rhys Wyndod.

The last months saw inward disintegration as well as submission to superior force. Nevertheless, Goronwy ap Heilin had committed himself to the struggle and died in rebellion, alongside the disinherited princes who stood with Dafydd ap Gruffudd in the last springtime of the principality of Wales, diehards who knew that theirs was not the heroism of a new beginning but the ultimate stand of the very last cohort clutching the figment of the political order that they had once been privileged to know.

Welsh in warfare

According to Sir John Edward Lloyd, the challenges of campaigning in Wales were exposed during the 20 year Norman invasion of Wales. If a defender could bar any road, control any river-crossing or mountain pass, and control the coastline around Wales, then the risks of extended campaigning in Wales were too great.

The Welsh method of warfare during the reign of Henry II is described by Gerald of Wales in his work Descriptio Cambriae written c. 1190;

"Their mode of fighting consists in chasing the enemy or in retreating. This light-armed people, relying more on their activity than on their strength, cannot struggle for the field of battle, enter into close engagement, or endure long and severe actions...though defeated and put to flight on one day, they are ready to resume the combat on the next, neither dejected by their loss, nor by their dishonour; and although, perhaps, they do not display great fortitude in open engagements and regular conflicts, yet they harass the enemy by ambuscades and nightly sallies. Hence, neither oppressed by hunger or cold, not fatigued by martial labours, nor despondent in adversity, but ready, after a defeat, to return immediately to action, and again endure the dangers of war."
The Historical Works of Giraldus Cambrensis translated by Sir Richard Colt-Hoare (1894), p.511


The Welsh were revered for the skills of their bowmen. Additionally, the Welsh learned from their Norman rivals. During the generations of warfare and close contact with the Normans, Gruffydd I and other Welsh leaders learned the arts of knighthood and adapted them for Wales. By Gruffydd's death in 1137 Gwynedd could field hundreds of heavy well-armed cavalry as well as their traditional bowmen and infantry.

"They make use of light arms, which do not impede their agility, small coats of mail, bundles of arrows, and long lances, helmets and shields, and more rarely greaves plated with iron. The higher class go to battle mounted on swift and generous steeds, which their country produces; but the greater part of the people fight on foot, on account of the marshy nature and unevenness of the soil. The horsemen, as their situation or occasion requires, willingly serve as infantry, in attacking or retreating; and they either walk bare-footed, or make use of high shoes, roughly constructed with untanned leather. In time of peace, the young men, by penetrating the deep recesses of the woods, and climbing the tops of mountains, learn by practice to endure fatigue through day and night."
The Historical Works of Giraldus Cambrensis translated by Sir Richard Colt-Hoare (1894), p.491


In the end Wales was defeated militarily by the improved ability of the English navy to blockade or seize areas essential for agricultural production such as Anglesey
Anglesey

. With control of the Menai Strait, an invading army could regroup on Anglesey; without control of the Menai an army could be stranded there; and any occupying force on Anglesey could deny the vast harvest of the island to the Welsh.

Lack of food would force the disbandment of any large Welsh force besieged within the mountains. Following the occupation Welsh soldiers were conscripted to serve in the English Army. During the revolt of Owain Glyndwr
