The Normans in Norfolk

Norfolk is one of England's greatest Norman counties and it was actually the Normans' administrative system from which the county comes – the invaders resolved the issue of the North and South peoples by making Norfolk and Suffolk.
The Normans also changed the way we called ourselves – they were keen to have surnames (note the French first syllable) that indicated a flag under which you would fight or a duke to whom you had allegiance. That's why we have the Christian mystic Julian of Norwich, who may well have come from a privileged background.
Norwich's role as the county capital dates from the post Conquest era when the Normans built the castle and Bishop De Losinga moved his headquarters from Thetford and founded Norwich Cathedral. Norwich became England's second largest medieval city after London and today is our most complete medieval city.
