Within the broader Post-Roman Britain period, Roman institutions gave way to competing Brittonic and Anglo-Saxon kingdoms while Christianity was rebuilt through continental and Irish missions. This event is placed at AD 655 in the chronology so it can be read alongside the political, military, social and cultural changes around it.
