Boudicca ( Boadicea ) was a Queen of the Iceni , a tribe occupying what is now East Anglia in the east of England. When she led an uprising, she came very close to driving the Romans out of Britain. Her name is the British ( Brittonic ) equivalent of Latin Victoria. She was probably not known as Boudicca by her own people.
The Brittonic word ‘ceni’ means ‘blade’ . Is it coincidence that the West Germanic word ‘sax’ (hence Saxon) also means ‘blade’? So could it have been that the Iceni were Saxons? Saxons certainly lived on the Saxon shore of the Thames estuary in the later period. The Anglian King Penda (a Brittonic name) was an Iceling, i.e., a member of the Icel tribe. From ‘Iceni’ to ‘Icel’ is a short step, with the mere substitution of’l’ for ‘n’ (Barcelona was earlier Barcenona); Icel could easily derive from Iceni.
In ancient times it was easier to cross the North sea than to cross England, because of the wild forests and difficult land which occupied the middle of the Country, so that the people in Eastern England would have more in common with the folk of Holland and Denmark than those on the Western side of Britain. It was not until the Romans drove roads through the wilderness that access became easier over land. The Belgae who occupied much of southern Britain were largely Germanic, perhaps there were Saxons amongst them.
