Deheubarth (Welsh pronunciation: [dɛˈhəɨbarθ]; lit. 'Right-hand Part', thus 'the South') was a regional name for the realms of south Wales, particularly as opposed to Gwynedd (Latin: Venedotia). 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 ("the Southern Britons") 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 (Y Gogledd), the northern lands whence Cunedda originated.

👉 Deheubarth in the context of Ednyfed Fychan
Ednyfed Fychan ap Cynfrig (Welsh pronunciation: [ɛdˈnəvɛd ˈvəχan ap ˈkənvrig], died 1 October 1246) was a Welsh nobleman who became distain (roughly equivalent to the position of seneschal) of Gwynedd in north Wales. He served in this position under the princes of Gwynedd for almost thirty years. Ednyfed's tenure as distain appears to have coincided with the transformation of the office from one of domestic service to that of being the prince of Gwynedd's closest adviser and agent. He is recorded witnessing Llywelyn ab Iorwerth's charters, carrying out diplomatic missions, administering justice, and perhaps even leading military action on the prince's behalf. After Llywelyn's death in 1240, Ednyfed served in the same position under Llywelyn's son and successor Dafydd, and is repeatedly recorded leading diplomatic missions on Dafydd's behalf to his rebellious brother Gruffudd and Henry III. Ednyfed died some eight months after Dafydd, probably on 1 October 1246.
Ednyfed established a ministerial dynasty which would serve the princes of Gwynedd for over thirty years after his death until the Edwardian conquest. His preeminence allowed him to marry Gwenllian, a daughter of the Lord Rhys, prince of Deheubarth. Ednyfed's sons succeeded him as disteiniaid and his descendants held a monopoly on the position until the final campaign of Llywelyn ap Gruffudd in December 1282, the turning point of Edward I's conquest of Wales. Even after the Conquest, Ednyfed's heirs and the heirs of his brothers, known as the Wyrion Eden 'descendants of Ednyfed', enjoyed special privileges in their tenure first granted by the Llywelyns. They held their lands free from all renders other than military service, which allowed them to become very wealthy and influential. Ednyfed's descendants spread across Wales, and many served in the new English administration. Ednyfed's grandson Tudur Hen ap Goronwy established the branch of the family known as the Tudors of Penmynydd in Anglesey, which produced leading ecclesiastical and administrative figures of the fourteenth century in Wales. Owen Tudor, grandfather of Henry VII, was a member of this family, thus making Ednyfed the first distinguished ancestor of the House of Tudor.

Deheubarth in the context of Gruffudd ap Llywelyn
Gruffudd ap Llywelyn (c. 1010 – 5 August 1063) was the only Welsh king to unite all of Wales, ruling from 1055 to 1063. He had previously been King of Gwynedd and Powys from 1039 to 1055. Gruffudd was the son of Llywelyn ap Seisyll, King of Gwynedd, and Angharad, daughter of Maredudd ab Owain, King of Deheubarth, and the great-great-grandson of Hywel Dda. After his death, Wales was again divided into separate kingdoms.
Deheubarth in the context of West Wales
West Wales (Welsh: Gorllewin Cymru) is a region of Wales.
It has various definitions, either covering Pembrokeshire, Ceredigion and Carmarthenshire, which historically comprised the Welsh principality of Deheubarth, and an alternative definition is to include Swansea and Neath Port Talbot, but exclude Ceredigion. The West Wales and the Valleys NUTS area also includes more westerly parts of North Wales as well as the South Wales Valleys.
Deheubarth in the context of Carmarthenshire
Carmarthenshire (/kərˈmɑːrðənʃər, -ʃɪər/ kər-MAR-dhən-shər, -sheer; Welsh: Sir Gaerfyrddin [ˈsiːr ɡaːɨrˈvərðɪn] or informally Sir Gâr) is a county in the south-west of Wales. The three largest towns are Llanelli, Carmarthen and Ammanford. Carmarthen is the county town and administrative centre. The county is known as the "Garden of Wales" and is also home to the National Botanic Garden of Wales.
Carmarthenshire has been inhabited since prehistoric times. The county town was founded by the Romans, and the region was part of the Kingdom of Deheubarth in the High Middle Ages. After invasion by the Normans in the 12th and 13th centuries it was subjugated, along with other parts of Wales, by Edward I of England. There was further unrest in the early 15th century, when the Welsh rebelled under Owain Glyndŵr, and during the English Civil War.
Deheubarth in the context of Llywelyn ap Seisyll
Llywelyn ap Seisyll (died 1023) was a king of Gwynedd in the 11th century who ruled over the Welsh kingdoms of Gwynedd, Powys and Deheubarth.
Deheubarth in the context of Maredudd ab Owain
Maredudd ab Owain (died c. 999) was a Welsh monarch, ruling in Gwynedd, Deheubarth and Powys. A member of the House of Dinefwr, his patrimony was the kingdom of Deheubarth comprising the southern realms of Dyfed and Seisyllwg. Upon the death of his father King Owain ap Hywel Dda around 988, he also inherited the kingdoms of Gwynedd and Powys, which he had conquered for his father. He was counted among the Kings of the Britons by the Chronicle of the Princes.
Maredudd was the younger son of King Owain ap Hywel Dda of Deheubarth and the grandson of King Hywel Dda. Owain had inherited the kingdom through the early death of his brothers and Maredudd, too, came to the throne through the death of his elder brother Einion around 984. Around 986, Maredudd captured Gwynedd from its king Cadwallon ab Ieuaf. He may have controlled all Wales apart from Gwent and Morgannwg.
Deheubarth in the context of Hywel Dda
Hywel ap Cadell, commonly known as Hywel Dda, which translates to Howel the Good in English, was a Welsh king who ruled the southern Welsh kingdom of Deheubarth and eventually came to rule most of Wales. He became the sole king of Seisyllwg in 920 and shortly thereafter established Deheubarth, and proceeded to gain control over the entire country from Prestatyn to Pembroke. As a grandson of Rhodri Mawr through his father Cadell, Hywel was a member of the Dinefwr branch of the dynasty. He was recorded as King of the Britons in the Annales Cambriæ and the Annals of Ulster.
Hywel is highly esteemed among other medieval Welsh rulers. His name is particularly linked with the codification of traditional Welsh law, which were thenceforth known as the Laws of Hywel Dda. The latter part of his name (Dda, lit. "Good") refers to the fact that his laws were just and good. The historian Dafydd Jenkins sees in them compassion rather than punishment, plenty of common sense and recognition of the rights of women. Hywel Dda was a well-educated man even by modern standards, having a good knowledge of Welsh, Latin and English.
Deheubarth in the context of Emlyn
Emlyn was one of the seven cantrefi of Dyfed, an ancient district of Wales, which became part of Deheubarth in around 950. It consisted of the northern part of Dyfed bordering on the River Teifi. Its southern boundary followed the ridge of the line of hills separating the Teifi valley from the valleys of the Tâf and Tywi.
Deheubarth in the context of Cantref Gwarthaf (Dyfed)
Cantref Gwarthaf was the largest of the seven cantrefi of Dyfed in southwest Wales. It subsequently became part of Deheubarth in around 950. It consisted of the southeastern part of Dyfed containing most of the basin of the River Tâf, parts of modern-day Pembrokeshire and Carmarthenshire.
The name means "upper-most zone". Its area was about 244 square miles (630 km). Unlike the other Dyfed cantrefi which were divided into two (or fewer) commotes, Cantref Gwarthaf was divided into eight commotes: Amgoed, Derllys, Efelfre, Elfed, Penrhyn, Peuliniog, Talacharn, and Ystlwys. Its civil headquarters were at Carmarthen. Its ecclesiastical centre (and perhaps, in the Age of the Saints, the seat of a bishop) was probably also Carmarthen, although the churches at Llanddowror and Meidrim were also important.
