Brythons

The Britons, also known as Celtic Britons or ancient Britons, were a Celtic people who inhabited Great Britain from at least the British Iron Age until the High Middle Ages. They spoke Common Brittonic, the ancestor of modern Brittonic languages. Early evidence of the Britons comes from Greco-Roman writers during the Iron Age. Ancient Britain comprised many tribes and kingdoms, and the Britons followed an ancient Celtic religion led by druids. The Roman Empire conquered most of Britain in the 1st century AD, forming the province of Britannia, though northern Brittonic tribes like the Caledonians and Picts remained unconquered. A Romano-British culture emerged, with British Latin coexisting with Brittonic. Following Roman rule's end in the 5th century, Anglo-Saxon settlement began, and the Britons' culture and language gradually fragmented.
