Monmouthshire: History
=== Pre-History ===
Evidence of human activity in the Mesolithic period has been found across Monmouthshire; examples include remains on the Caldicot and Wentloog Levels and at Monmouth. A major hoard of Bronze Age axes was discovered at St Arvans. The county has a number of hillfort sites, such as those at Bulwark and Llanmelin Wood. The latter has been suggested as the capital of the Silures, a Celtic tribe who occupied south-east Wales in the Iron Age. The Silures proved among the most intractable of Rome's opponents; Tacitus described them as "exceptionally stubborn" and Raymond Howell, in his county history published in 1988, notes that while it took the Romans five years to subdue south-east England, it took thirty-five before complete subjugation of the Silurian territories was achieved.
The Roman conquest of Britain began in AD 43, and within five years the Roman Empire's legions had reached the borders of what is now Wales. In south east Wales they encountered strong resistance from the Silures, led by Caratacus (Caradog), who had fled west after the defeat of his own tribe, the Catuvellauni. His final defeat in AD 50 saw his transportation to Rome, but Silurian resistance continued, and the subjugation of the entirety of south east Wales was not achieved until around AD 75, under the governor of Britain, Sextus Julius Frontinus.
Monmouthshire's most important Roman remains are found at the town of Venta Silurum ("Market of the Silures"), present-day Caerwent in the south of the county. The town was established in AD 75, laid out in the traditional rectangular Roman pattern of twenty insulae with a basilica and a temple flanking a forum. Other Roman settlements in the area included Blestium (Monmouth). The Romanisation of Monmouthshire was not without continuing civil unrest; the defences at Caerwent, and at Caerleon, underwent considerable strengthening in the late 2nd century in response to disturbances. The Silurian identity was not extinguished: the establishment of a Respublica Civitatis Silurium (an early town council) at the beginning of the 3rd century testifies to the longevity of the indigenous tribal culture. …
