Rhys ap Gruffydd or ap Gruffudd was the ruler of the kingdom of Deheubarth in south Wales from 1155 to 1197. Today, he is commonly known as The Lord Rhys, in Welsh Yr Arglwydd Rhys, although this title may have not been used in his lifetime. He usually used the title "Proprietary Prince of Deheubarth" or "Prince of South Wales", but two documents have been discovered in which he uses the title "Prince of Wales" or "Prince of the Welsh". Rhys was one of the most successful and powerful Welsh princes, and, after the death of Owain Gwynedd of Gwynedd in 1170, the dominant power in Wales.

Newcastle Emlyn is a town on the River Teifi, straddling the counties of Ceredigion and Carmarthenshire in west Wales. It is also a community entirely within Carmarthenshire, bordered by those of Llangeler and Cenarth, both being in Carmarthenshire; and by Llandyfriog in Ceredigion.

Seisyllwg was a petty kingdom of medieval Wales. It is unclear when it emerged as a distinct unit, but according to later sources it consisted of the former Kingdom of Ceredigion plus the region known as Ystrad Tywi. Thus it covered the modern county of Ceredigion, part of Carmarthenshire, and the Gower Peninsula. It is evidently named after Seisyll, king of Ceredigion in the 7th or early 8th century, but it is unknown if he was directly responsible for its establishment. In the 10th century Seisyllwg became the center of power for Hywel Dda, who came to rule most of Wales. In 920 Hywel merged Seisyllwg with the Kingdom of Dyfed to form the new kingdom of Deheubarth.
Rhain ap Cadwgan was an 8th-century king of Dyfed and Brycheiniog in Wales of the Early Middle Ages. He succeeded his father Cadwgan, who succeeded his father Caten ap Cloten.
The Kingdom of Dyfed is one of several Welsh petty kingdoms that emerged in 5th-century sub-Roman Britain in southwest Wales based on the former territory of the Demetae. Following the Norman invasion of Wales between 1067–1100, the region was conquered by the Normans and by 1138 incorporated into a new shire called Pembrokeshire after the Norman castle built in the Cantref of Penfro and under the rule of the Marcher Earl of Pembroke.
Ystrad Tywi is a region of southwest Wales situated on the both banks of the River Tywi. Although Ystrad Tywi was never a kingdom itself, it was historically a valuable territory and was fought over by the various kings of Dyfed, Deheubarth, Seisyllwg, Gwynedd, Morgannwg and the Normans.

Creuddyn was a medieval commote and, later, a lordship in Ceredigion, Wales. It was located between the rivers Ystwyth and Rheidol, and was one of the three commotes of Cantref Penweddig. The name, of Old Welsh origin, probably refers to the Pen Dinas hill fort, anciently known as Dinas Maelor. The natural centre of the commote was Llanfihangel y Creuddyn where five roads meet at the village. The name survives in the name of a rural community and church of the same name; however the modern community is much smaller than the medieval commote.
