Glamorgan

Glamorgan (/ɡləˈmɔːrɡən/), or sometimes Glamorganshire (Welsh: Morgannwg [mɔrˈɡanʊɡ] or Sir Forgannwg [ˈsiːr vɔrˈɡanʊɡ]), was one of the thirteen counties of Wales that existed from 1536 until their abolition in 1974. It is located in South Wales. Originally an early medieval petty kingdom of varying boundaries known in Welsh as Morgannwg (or Glywysing), which was then invaded and taken over by the Normans as the Lordship of Glamorgan. The area that became known as Glamorgan was both a rural, pastoral area, and a conflict point between the Norman lords and the Welsh princes. It was defined by a large concentration of castles.

After falling under English rule in the 16th century, Glamorgan became a more stable county, and exploited its natural resources to become an important part of the Industrial Revolution. Glamorgan was the most populous and industrialised county in Wales, and was once called the "crucible of the Industrial Revolution", as it contained the world centres of three metallurgical industries (iron, steel and copper) and its rich resources of coal.

Under the Local Government Act 1972, the county boroughs and administrative county of Glamorgan were abolished on 1 April 1974, with three new counties being established, each containing a former county borough: West Glamorgan, Mid Glamorgan, South Glamorgan. The name also survives in that of Vale of Glamorgan, a county borough.

Glamorgan comprised distinct regions: the industrial valleys, the agricultural vale and the scenic Gower Peninsula. The county had boundaries with Brecknockshire (north), Monmouthshire (east), Carmarthenshire (west), and to the south it was bordered by the Bristol Channel. The total area was 2,100 km² (811 sq mi). Glamorgan contained two cities, Cardiff, the county town and from 1955 the capital city of Wales, and Swansea. The highest point in the county was Craig y Llyn (600 metres (1,969 ft)) near the village of Rhigos in the Cynon Valley.

Glamorgan's terrain has been inhabited by humankind for over 200,000 years. Climate fluctuation caused the formation, disappearance, and reformation of glaciers which, in turn, caused sea levels to rise and fall. At various times life has flourished, at others the area is likely to have been completely uninhabitable. Evidence of the presence of Neanderthals has been discovered on the Gower Peninsula. Whether they remained in the area during periods of extreme cold is unclear. Sea levels have been 150 metres (490 ft) lower and 8 metres (26 ft) higher than at present, resulting in significant changes to the coastline during this period.

Archaeological evidence shows that humans settled in the area during an interstadial period. The oldest known human burial in Great Britain – the Red Lady of Paviland – was discovered in a coastal cave between Port Eynon and Rhossili, on the Gower Peninsula. The 'lady' has been radiocarbon dated to c. 29,000 years before present (BP) – during the Late Pleistocene – at which time the cave overlooked an area of plain, some miles from the sea.

From the end of the last ice age (between 12,000 and 10,000 BP) Mesolithic hunter-gatherers began to migrate to the British Peninsula – through Doggerland – from the European mainland. Archaeologist Stephen Aldhouse-Green notes that while Wales has a "multitude" of Mesolithic sites, their settlements were "focused on the coastal plains", the uplands were "exploited only by specialist hunting groups".

Human lifestyles in North-West Europe changed around 6000 BP; from the Mesolithic nomadic lives of hunting and gathering, to the Neolithic agrarian life of agriculture and settlement. They cleared the forests to establish pasture and to cultivate the land and developed new technologies such as ceramics and textile production. A tradition of long barrow construction began in continental Europe during the 7th millennium BP – the free standing megalithic structures supporting a sloping capstone (known as dolmens); common over Atlantic Europe. Nineteen Neolithic chambered tombs (or long barrows) and five possible henges have been identified in Glamorgan. These megalithic burial chambers, or cromlechi, were built between 6000 and 5000 BP, during the early Neolithic period, the first of them about 1500 years before either Stonehenge or the Egyptian Great Pyramid of Giza was completed. Two major groups of Neolithic architectural traditions are represented in the area: portal dolmens (e.g. St Lythans burial chamber (Vale of Glamorgan), and Cae'rarfau (near Creigiau)); and Severn-Cotswold chamber tombs (e.g. Parc Cwm long cairn, (Parc le Breos Cwm, Gower Peninsula), and Tinkinswood burial chamber (Vale of Glamorgan)), as well as tombs that do not fall easily into either group. Such massive constructions would have needed a large labour force – up to 200 men – suggestive of large communities nearby. Archaeological evidence from some Neolithic sites (e.g. Tinkinswood) has shown the continued use of cromlechi in the Bronze Age.
