Overview

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 until the High Middle Ages, at which point they diverged into the Welsh, Cornish, and Bretons. They spoke Common Brittonic, the ancestor of the modern Brittonic languages.

The record

The best-attested series in each category; where several projects publish the same quantity, the one with the most observations is shown. Each row is the most recent value the record holds at or before 1235 CE, shown with the year that value belongs to. Some statistical series also publish forward projections — the year column is the honest guide. Nothing on this page is interpolated or estimated by us.
