Ancient Britons
The Britons, also known as Celtic Britons or Ancient Britons were the Celtic people who inhabited Great Britain from at least the British Iron Age and into the Middle Ages, at which point they diverged into the Welsh, Cornish and Bretons. They spoke the Common Brittonic language, the ancestor of the modern Brittonic languages. The earliest written evidence for the Britons is from Greco-Roman writers and dates to the Iron Age. Celtic Britain was made up of many tribes and kingdoms, associated with various hillforts. The Britons followed an Ancient Celtic religion overseen by druids. Some of the southern tribes had strong links with mainland Europe, especially Gaul and Belgica, and minted their own coins. The Roman Empire conquered most of Britain in the 1st century, creating the province of Britannia. The Romans invaded northern Britain, but the Britons and Caledonians in the north remained unconquered and Hadrian's Wall became the edge of the empire.
