In AD 1066, the Norman invasion of Britain overpowered the
Saxon-Dane rulers. They brought with them the feudal system of government or
feudalism. They establish the King of England. From then, England was changed
for ever. Normans spoke a variant of Frankish language or French and were known
to build castles everywhere, which served as the main form of defense. In the feudal
system of government, commoners worked and fought for nobles in exchange for
protection and the use of land.
