Sure, here are some key points about Norman Rule:

Norman Conquest

William the Conqueror became the king of England in 1066 after the Battle of Hastings. His rule marked the start of Norman rule.
The Domesday Book, commissioned in 1085, provides detailed information on land ownership and gives us a clear picture of society under Norman rule.

Feudal System

The Feudal System was introduced across England. This replaced the Anglo-Saxon system of local government with a hierarchy of land ownership and obligations.
Under the Feudal System, all land belonged to the king, and he granted land to his lords in return for military service.

Legal Changes

William merged Anglo-Saxon law with Norman customs. The resulting common law had a profound impact on England’s legal system.
William established royal control over the legal system, making the crown the ultimate arbiter of justice.

Church Reforms

Norman rule saw the imposition of the Continental practise of celibacy for priests, transforming the English Church.
The establishment of Norman style cathedrals and castles across the country symbolised Norman ecclesiastical and secular authority.

Linguistic Impact

The Norman Conquest led to the addition of thousands of French words into the English language, changing it significantly.

These points lay a good foundation for understanding the impact of Norman Rule in England. Remember to use primary resources like the Domesday Book and the laws imposed by William the Conqueror to gain a stronger understanding of the period.
