The House of Aberffraw was a medieval royal court based in the village it was named after, Aberffraw, Anglesey (Wales, UK) within the borders of the then Kingdom of Gwynedd. The dynasty was founded in the 9th century by a King in Wales whose descendants founded the Welsh Royal Houses. The other medieval Welsh dynasties were the Royal Houses of Dinefwr, Mathrafal. [1]

Contents

The Royal House is deemed to be a historiographical and genealogical term historians use to illustrate the line of succession from Rhodri the Great of Wales through his eldest son Anarawd from the 870s AD. [2] [3] The dynasty thrived for centuries until the demise of the royal family during the 13th century. The royal house culminated in the conquest of Wales by Edward I, and the death of the last Prince, Dafydd III in 1283. The final lineal direct descendant of the House of Aberffraw was Owain Lawgoch, he died in the 14th century. Several Welsh noble families have since claimed male descent from family.

Aberffraw hundred (cantref)

The name of the royal house derives from Aberffraw, on Anglesey (Ynys Môn) at the mouth of the River Ffraw. The royal court is where the early Kings of Gwynedd established their principal (chief) family seat. [4] The site was a preshistoric settlement later occupied during the Roman period (c.0- 400 AD ). The town became a Welsh Princely court (Welsh : Llys) and location of a royal palace as part of the administrative centre and one of the three county divisions (hundred, Welsh : cantref) of Anglesey. [lower-alpha 1] [6] [7] [8] An early Gwynedd King, Cadfan ap Iago was buried at St. Cadwaladr's Church in the then Aberffraw hundred. Cadfan's tombstone (634 AD) is on display in the church today and reads: [6] [9]

Welsh dynasties

In the 9th century, Rhodri the Great (Welsh : Mawr) had inherited multiple Welsh Kingdoms, Gwynedd from his father Merfyn Frych (Manx Chieftain), Powys from his mother Nest and he added Seisyllwg (Ceredigion and Ystrad Tywi) by a dynastic marriage to Angharad of Seisyllwg. Rhodri divided Wales into at least 3 provinces, his son Anarawd ap Rhodri was given the Kingdom of Gwynedd and founded the medieval dynasty the House of Aberffraw. Merfyn ap Rhodri was given the Kingdom of Powys. And another of Rhodri's sons, Cadell ap Rhodri was given the province of Deheubarth and began the House of Dinefwr. Wales was subsequently separated into North Wales, Mid Wales and South Wales respectively. [11] [12] [13]

Succession

Royal succession within the House of Aberffraw (as with succession in Wales in general) was a complex matter due to the unique character of Welsh law. [14] According to Hubert Lewis, though not explicitly codified as such, the edling, or heir apparent, was by convention, custom, and practice the eldest son of the lord or Prince and was entitled to inherit the position and title as "head of the family" from the father. This was effectively primogeniture with local variations. However, all sons were provided for out of the lands of the father, and in certain circumstances so too were daughters (with children born both in and out of wedlock considered legitimate). [14] Men could also claim royal title through the maternal patrimony of their mother's line in certain circumstances (which occurred several times during the period of Welsh independence). [15] The female line of the dynasty was also considered to remain royal, as marriage was an important means of strengthening individual claims to the various kingdoms of Wales and uniting various royal families to that of Aberffraw, or reuniting factions after dynastic civil wars (for example with the marriage of Hywel Dda, a member of the Dinefwr branch of the Aberffraw dynasty, and Elen of Dyfed, daughter of Llywarch ap Hyfaidd, King of Dyfed). [16] This meant that the female line was considered as a legitimate path of royal descent within the House of Aberffraw, with the claims of royal women to titles usually transferring to their sons.[ citation needed ]

Cambro-Norse era

During the Cambro-Norse era (850s 1100s), Wales was subjected to Viking raids all throughout the country between 852 and 919 (the Jómsvíkinga saga refers to that period). An example of this pattern was with the Viking leader Ingimund who was expelled from Dublin and tried unsuccessfully to establish a base on Anglesey (c.902), but instead left for Chester. [17]

The Welsh Kingdoms had been subject to the Kingdom of Mercia from the 7th century onwards. This led to the construction of Offa's Dyke, a territorial land border between England and Wales built in the mid to late 8th century. However, war broke out against the English for decades from 853, this culminated in a victory for The Welsh Kingdoms of Gwynedd and Powys against the English Mercian and Wessex Kingdoms who had been assisted by Anglo-Saxons and Danes (Vikings). [12] [18] [19]

After successful battles for Rhodri the Great against the Vikings, beginning with the death of Horn the Dane (leader of the 'New Dubliners') in 856, Rhodri was then killed in battle against the Saxon leader Ceowulf of Mercia in 878 AD. But the Welsh would avenge their King with a victory over the English Mercians at the Battle of the Conwy in 881. During this period, Rhodri Mawr's sons were dependent for protection from the Scandinavian York Viking mercenaries. [12] [17] [20] [21] [22]

The second phase of Viking raids in Wales continued into the 10th century. Between the years 950–998, Wales saw raids, attacks, and slave raids with a devastating Viking raid happening at Aberffraw in 968. King Maredudd ab Owain would pay the ransom for the return of Welshmen. Then the third phase of Viking raids would coincide with the Norman invasion of Wales during the 11th century. This era saw a new alliance between the Vikings and the house of Aberffraw through the marriage of Gruffudd ap Cynan's father Cynan ab Iago to the daughter of a Norseman after he took refuge in the Kingdom of Dublin. After several attempts to retake Gwynedd from the Normans, Gruffudd eventually succeeded with assistance from Magnus Barefoot (King of Dublin, King of Norway and King of the Isles) in 1098 when they won the Battle of Anglesey Sound against the English Normans together. [17] [23] [24] [ page needed ] [25]

Power base (Norman invasion)

The family were able to assert their influence within Gwynedd, their traditional sphere of influence, but by the 11th century they were ousted from Powys ( Mid Wales ) and Deheubarth ( West Wales ) by a series of strong rulers from the House of Dinefwr in Deheubarth, their dynastically junior cousins. The Dinefwr family were descended from the Cadell ap Rhodri, the second son of Rhodri the Great. However, under Gruffudd ap Cynan, the house of Aberffraw was able to recover it's heritage and position during the Norman invasion of Gwynedd (1081–1100) with Cynan as King of Gwynedd defeating the Norman invaders. [26] Owain Gwynedd, Gruffudd's son defeated King Henry II of England and the vast Angevin host in the 1157 campaign and again in 1166. That led to Owain being proclaimed as the Prince of Wales ( Latin : Princeps Wallensium) by other Welsh rulers. The proclamation reasserted and updated the Aberffraw claims to be the principal royal house of Wales, as senior line descendants of Rhodri the Great. [27] [lower-alpha 2] [lower-alpha 3]

Princes of Wales (de facto)

The Kingdoms of Wales defended their territory from Anglo-Normans and subsequent Kings of England's military expeditions 21 times between 1081 1267. It was King Edward I of England who finally suppressed the Welsh Principality after Llywelyn ap Iorwerth (Llywelyn I, the Great) and his grandson, Llywelyn ap Gruffudd (Llywelyn II) had controlled all of medieval Wales. As Llywelyn II was a second son and direct (lineal) descendant of Rhodri Mawr and Owain Gwynedd, his succession caused number of problems within the House of Aberffraw. The 13th century Llywelyns, rulers of Wales controlled their neighbouring Kingdoms through a political framework whilst excluding and subduing the descendants of Norman marcher lords through warfare. [30] [31]

Llywelyn the Great

By 1203 Llywelyn ap Iorwerth (Llywelyn I, the Great) had followed in the footsteps of his grandfather, Owain Gwynedd, and unified the divided Kingdom of Gwynedd. He further advanced to conquer all of Wales by 1207. King John I of England (Llywelyn's father-in-law) intervened in Powys returning the Kingdom to Prince Gwenwynwyn in 1209, however, the intervention caused a retaliation in the form of the Welsh uprising of 1211. Llywelyn would gain favour from Pope Innocent III who excommunicated King John and encouraged the Welsh Principality to rebel against English rule. After the signing of the Magna Carta on the 15th of June 1215, Llywelyn was recognised as Prince and ruler of all Wales. In 1216 Llywelyn the Great had received the fealty and homage of the Dinefwr rulers of Deheubarth at the Council of Aberdyfi. [32] [33] [34] With homage and fealty paid by other Welsh lords to Llywelyn at Aberdyfi, Llywelyn the Great became the de facto first Prince of Wales in the modern sense. This was confirmed in a 1218 meeting in Worcester, England, by the next English monarch, Henry III. Llywelyn acted as Overlord to other nobles. By 1230 Llywelyn styled himself as the Prince of Aberffraw and Lord of Snowdon. [32] [33]

13th century

During the 13th century, Wales was ruled by Dafydd ap Llywelyn (Dafydd II), son of Llywelyn the Great. After the death of Dafydd II, the power was given to his nephew, Llywelyn ap Gruffudd (Prince Llywelyn II) who was granted the title of Prince of Wales by his English compatriot Henry III at the Treaty of Montgomery during 1267. Prince Llywelyn II was killed in action campaigning for Welsh independence in Cilmeri, December 1282. Of the Aberffraw dynasty the final Prince of Wales was Dafydd ap Gruffydd (Prince Dafydd III). After the death of Dafydd III's brother, the Prince himself would be tried for treason and executed in Shrewsbury, England, by his once ally Edward I of England on 3 October 1283. [35] [36] [37] The consequences of the 1282-83 Conquest of Wales by Edward I greatly reduced the influence of the family. King Edward I forced the remaining members of the family to surrender their claim to the title of Prince of Wales under the Statute of Rhuddlan in 1284, which also abolished the independent Welsh peerage.[ citation needed ] The Aberffraw family members closest to Llywelyn II were imprisoned for life by Edward, while the more distant Aberffraw members went into deep hiding and fell into obscurity. Other members of the family did lay claim to their heritage; they included Owain Lawgoch as the lineal successor to Llywelyn II in the 14th century. [35] [36] [38]

Deheubarth was a regional name for the realms of south Wales, particularly as opposed to Gwynedd. It is now used as a shorthand for the various realms united under the House of Dinefwr, but that Deheubarth itself was not considered a proper kingdom on the model of Gwynedd, Powys, or Dyfed is shown by its rendering in Latin as dextralis pars or as Britonnes dexterales and not as a named land. In the oldest British writers, Deheubarth was used for all of modern Wales to distinguish it from Hen Ogledd, the northern lands whence Cunedda originated.

More precisely, and based on the Romano-British tribal lands of the Ordovices in the west and the Cornovii in the east, its boundaries originally extended from the Cambrian Mountains in the west to include the modern West Midlands region of England in the east. The fertile river valleys of the Severn and Tern are found here, and this region is referred to in later Welsh literature as "the Paradise of Powys".

As Celtic Britons, the House of Dinefwr was ruling before the Norman conquest, having to fight with their neighbors such as the Celtics, Anglo-Saxons and Vikings, before struggling with the Normans afterwards. Many members of this family were influential in Welsh history, such as Hywel Dda, who codified Welsh law under his rule, and achieved the important title of King of the Britons, or Lord Rhys, Prince of Wales, who rebelled against Richard the Lionheart, and became one of the most powerful Welsh leaders of the Middle Ages.

<span class="mw-page-title-main">History of Gwynedd during the High Middle Ages</span>

The history of Gwynedd in the High Middle Ages is a period in the History of Wales spanning the 11th through the 13th centuries. Gwynedd, located in the north of Wales, eventually became the most dominant of Welsh polities during this period. Contact with continental courts allowed for Gwynedd to transition from a petty kingdom into an increasingly sophisticated principality of seasoned courtiers capable of high level deplomacy and representation; not only with the Angevine kings, but also the king of France and the Papal See. Distinctive achievements in Gwynedd include further development of Medieval Welsh literature, particularly poets known as the Beirdd y Tywysogion associated with the court of Gwynedd; the reformation of bardic schools; and the continued development of Cyfraith Hywel. All three of these further contributed to the development of a Welsh national identity in the face of Anglo-Norman encroachment of Wales.

<span class="mw-page-title-main">House of Mathrafal</span> Welsh royal family

The Royal House of Mathrafal began as a cadet branch of the Welsh Royal House of Dinefwr, taking their name from Mathrafal Castle. They effectively replaced the House of Gwertherion, who had been ruling the Kingdom of Powys since late Roman Britain, through the politically advantageous marriage of an ancestor, Merfyn the Oppressor. King Bleddyn ap Cynfyn would join the resistance of the Anglo-Saxon King Harold Godwinson, against the invasion of William the Conqueror, following the Norman conquest of England. Thereafter, they would struggle with the Plantagenets and the remaining Welsh Royal houses for the control of Wales. Although their fortunes rose and fell over the generations, they are primarily remembered as Kings of Powys and last native Prince of Wales.
