(Welsh pronunciation: [dɛˈhəɨbarθ]; lit. "Right-hand Part", thus "the South")[4] 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[5] is shown by its rendering in Latin as dextralis pars or as Britonnes dexterales ("the Southern Britons") and not as a named land.[6] In the oldest British writers, Deheubarth
was used for all of modern Wales
to distinguish it from Hen Ogledd

was united around 920 by Hywel Dda
Hywel Dda
out of the territories of Seisyllwg
and Dyfed, which had come into his possession. Later on, the Kingdom of Brycheiniog
was also added. Caerleon
was previously the principal court of the area, but Hywel's dynasty fortified and built up a new base at Dinefwr, near Llandeilo, giving them their name. After the high-water mark set by Hywel, Dinefwr was repeatedly overrun. First, by the Welsh of the north and east: by Llywelyn ap Seisyll of Gwynedd in 1018; by Rhydderch ab Iestyn of Morgannwg
in 1023; by Gruffydd ap Llywelyn
Gruffydd ap Llywelyn
of Gwynedd in 1041 and 1043. In 1075, Rhys ab Owain and the noblemen of Ystrad Tywi
Ystrad Tywi
succeeded in treacherously killing their English-backed overlord Bleddyn ap Cynfyn. Although Rhys was quickly overrun by Gwynedd and Gwent, his cousin Rhys ap Tewdwr
Rhys ap Tewdwr
– through his marriage into Bleddyn's family and through battle – reëstablished his dynasty's hegemony over south Wales
just in time for the second wave of conquest: a prolonged Norman invasion under the Marcher Lords. In 1093, Rhys was killed in unknown circumstances while resisting their expansion into Brycheiniog
and his son Gruffydd was briefly thrown into exile. Following the death of Henry I in 1136, Gruffydd formed an alliance with Gwynedd for the purpose of a revolt against Norman incursions. He took part in Owain Gwynedd
Owain Gwynedd
and Cadwaladr ap Gruffydd's victory over the English at Crug Mawr. The newly liberated region of Ceredigion, though, was not returned to his family but annexed by Owain. The long and capable rule of Gruffydd's son the Lord Rhys
Lord Rhys
– and the civil wars that followed Owain's death in Gwynedd – briefly permitted the South to reassert the hegemony Hywel Dda
Hywel Dda
had enjoyed two centuries before. On his death in 1197, though, Rhys redivided his kingdom among his several sons and none of them ever again rivalled his power. By the time Llywelyn the Great
Llywelyn the Great
won the wars in Gwynedd, in the late 12th century, lords in Deheubarth
merely appear among his clients. Following the conquest of Wales
by Edward I, the South was divided into the historic counties of Cardiganshire, Carmarthenshire
and Pembrokeshire
by the Statute of Rhuddlan. Religion[edit] In the arena of the church, Sulien was the leader of the monastic community at Llanbadarn Fawr in Ceredigion. Born ca. 1030, he became Bishop of St David's
Bishop of St David's
in 1073 and again in 1079/80. Both of his sons followed him into the service of the church. At this time the prohibition against the marriage of clerics was not yet established. His sons produced a number of manuscripts and original Latin and vernacular poems. They were very active in the ecclesiastical and political life of Deheubarth. One son, Rhygyfarch (Latin: Ricemarchus) of Llanbadarn Fawr, wrote the Life of Saint David
Saint David
and another, Ieuan, was a skillful scribe and illuminator. He copied some the works of Augustine of Hippo

and may have written the Life of St. Padarn. See also[edit]
