:^) The Britons were a collection of fractious tribes, city-states without cities (more like village-states), continuous trade but continual warfare and internal political struggles. There was trade going on with the Romans, and some piracy based in Britain.
Tribes with trade links with the Romans and in need of extra muscle to defend themselves against some neighboring tribe led inexorably to the Roman presence. The invasion force under Claudius was possibly the largest in British history.
Analogously, in the 11th c an Irish king, Cavanaugh, hired some Norman mercenaries to help him in some war of his own, and the Normans wound up sticking around. British rulers wound up with the whole island by the time of Elizabeth I, and this didn’t end until the early 20th c, with the UK still including the “outside six” of Northern Ireland.
The same process is going on now in the Irish republic, the UK, and the rest of western and northern Europe, but with koranimals. I’m sure it’ll be okay though. [smirk]
Thanks.
Today I learned that the early Britons are also called Celtic Britons. The Germans (who bombed Pearl Harbor) arrived in the fifth century. If I had paid attention in fifth grade, I’d have known that.
By the way, did Varus ever give back those Legions?
