Until very recently, Britain was inhabited almost exclusively by white Europeans. First, the Celts, then the Germanic tribes who became the English, and then the closely related Vikings. Our DNA was more or less settled by 900 AD. A smattering of others came over the next thousand years; Norman descendants of Vikings in 1066, and then a tiny number of Jews, Huguenots, African or Asian individuals associated with Britain’s empire, and even escaped slaves from the USA. But these were few and rapidly assimilated, becoming British and part of our island story.
