The history of the Normans began a long time before 1066. Originating
from the 'Norsemen' they were one of the most successful warrior tribes
of the Dark Ages that came to dominate Europe from the Baltic Sea to the
island of Sicily and the borders of Eastern Europe.
Beginning as Viking raiders in the eighth century, the Normans not only
changed the landscape of Europe but were changed by their new conquests.
As a military force they became unstoppable; as Conqerors, they
established their own kingdom in Normandy from where they set out on a
number of devastating campaigns, where they also introduced innovations
in politics, architecture and culture.
In A Brief History of the Normans Leading French historian, Francois
Neveux, gives an accessible and authoritative introduction.
