I wonder who the “native” Britons mostly wiped out, enslaved, and dominated when they crossed into Britain?
And the Anglo Saxons weren’t treated all that kindly by the Norman French, when they invaded in turn. Can you say “esne”?
If only those nasty, evil white male Anglo Saxons had lived up to their obligations under the Geneva Convention... but, I understand the Helvetii were too busy planning to invade Switzerland to enforce it.
Anglo-Saxons didn’t invent these practices; they were a normal risk of life: kill the surving fighters; enslave the ones fit to work; divvy up the women, gold, and cattle; burn the rest.
“The Book of Invasions” contains a somewhat mythologized version of four or five waves of people who took over in succession.
The book I posted in my post #5 has some beautiful distribution maps of the various migrating waves out of the Iberian refuge. In fact, you can tell from the DNA distributions when the English Channel finally opened up and isolated the continental R1b's from the Isles R1b's, etc.
