Deceangli

50 BCE – 48 CE (approx.)

People of north-east Wales, the first target of Roman campaigns into Wales in 48, whose lead mines soon stamped their name on Roman ingots.

Origins

The Deceangli lived in what is now Flintshire and Denbighshire, between the Dee estuary and the Clwyd valley, a region of hillforts such as Moel Hiraddug and Penycloddiau. They were probably a small Iron Age grouping of local communities and are first named by Tacitus.

Rule and society

Nothing is known of their rulers or society beyond the archaeology of their hillforts and farms. Their territory was rich in lead and silver ores on Halkyn Mountain, which the Romans quickly exploited; lead pigs found near Chester carry the inscription DECEANGL and a date of 74, showing that mining was organised under the name of the people.

Decline and legacy

In 48 the governor Ostorius Scapula marched against the Deceangli, ravaging their land almost to the Irish Sea before trouble among the Brigantes recalled him. The area was secured by the fortress of Chester in the 70s, and the Deceangli are not known to have formed a civitas of Roman Britain.

Few sources survive for this state; details are uncertain.
