Period in English history following the
defeat (1066) of King Harold of England by William, duke of Normandy, who
became William I of England.
The conquest was formerly thought to have brought about broad changes in
all phases of English life. More recently historians have stressed the
continuity of English law, institutions, and customs, but the subject remains
one of controversy. The initial military conquest of England was quick
and brutal. The members of the Anglo-Saxon upper class who were not killed
in the battle of Hastings were almost all involved in the rebellion from
1068 to 1070 and were either killed or deprived of their lands. Thus a
Norman aristocracy was superimposed on the English, and the new elite brought
with it Norman feudal customs, which were reinforced by the need for cohesion
and mutual military support among the fairly small group of conquerors.
Thus the rebellions among the Norman barons were minor and short-lived,
the interests of stability being paramount. To consolidate his position
William used the existing Anglo-Saxon administrative system, which functioned
as part of a centralized monarchical tradition. It was this tradition,
as adapted by the Normans, that gave English feudalism its uniquely cohesive
nature. There was little change in the administrative and judicial systems
during the Norman period (usually defined as ending with the accession
of the Plantagenet Henry II in 1154) and later developments were not in
the nature of Norman superimpositions. William I’s archbishop of Canterbury,
Lanfranc, established a separate system
of canon law courts, effectively asserted the supremacy of his archdiocese,
and brought the English church into closer contact with developments in
Europe, particularly with the reforms of Pope Gregory VII. The Norman kings,
however, successfully resisted papal encroachment on their control over
episcopal appointments. The period saw many churches and castles built,
the latter chiefly on the south and east coasts and on the Welsh and Scottish
borders . Norman French became the language of the court and upper classes,
and of literature, and had great effect on the development of the English
language.
