Editing Cwmcarn (section)

== Pre-industrial history ==
Significant settlement at Cwmcarn came with [[Bronze Age]] migration of local tribes from the [[Caldicot and Wentloog Levels|Gwent levels]] to the uplands of [[Mynydd y Grug]], [[Mynydd Machen]] and [[Mynydd Maen]] ([[Twmbarlwm]]) and led to a later [[Iron Age]] (900&ndash;55 BC) [[hillfort]] to be constructed by the [[Silures]] on [[Twmbarlwm]].

[[Ancient Rome|Roman]] forces took control of most of what became the [[Roman Britain|Roman]] province of [[Britannia Superior]] in 43 AD but then took a further 25 years to gain control of the present day South Wales valleys. [[Roman Empire|Roman]] control remained established until [[Roman withdrawal from Britain|full scale withdrawal]] in the 5th century AD when the Kingdoms of [[Kingdom of Gwent|Gwent]] and [[Glywysing]] were established. Gwent was defined as the land between the [[River Usk]] and the [[River Wye]] and Glywysing, the land between the [[River Usk]] and the [[River Tawe]]. Cwmcarn, located where the Carn and Ebbw river valleys meet, being situated within the Welsh Kingdom of [[Glywysing]].

The [[Welsh placename]] of Cwmcarn came about in 942 when Llywarch ap Cadogan gave Villa Treficarn Pont ('estate near the bridge over the Carn') to a [[Bishop of Llandaff]] named Wulfrith with King Cadell's guarantee, i.e. the place where the Carn meets the Ebbw (now Cwmcarn).

Following the [[Norman invasion of Wales]] the separate townships of [[Abercarn]], Cwmcarn and [[Newbridge, Caerphilly|Newbridge]] were given a [[manorial]] title of Abercarne. The three townships were also within the boundaries of the ancient parish of [[Mynyddislwyn]] and remained therein up until comparatively recent times.
