Magnus Magnusson taking our troops abroad with him to usurp Gratian's Western Roman Empire before losing his life in battle against Theodosius in 388 was the reason we couldn't defend ourselves, we were left defenceless! We allowed the Germans to come to our aid, they settled in Kent, and came and came and came; the 6th century held them back for a while, but then still they came and came, then the Irish attacked from the north leaving us Cymru/Wales, Kernow/Cornwall, and the creation of Breizh/Brittanny. Then they in their turn were attacked by the Danes before being conquered by the Normans. Since when all their royalty has been foreign, except for the Tudor family who in truth should have been the Merediths, and Cromwell the protector who was really a Williams from Caerdydd/Cardiff.
