This document summarizes events in England between 1066 and 1485:
1) William the Conqueror invaded England in 1066 after Edward the Confessor's death, establishing Norman rule and gradually replacing Anglo-Saxon culture with Norman-French culture.
2) Feudalism became the dominant economic and social system, and the French language was used among the aristocracy. Chivalry also became an important influence on nobility.
3) Events like the signing of the Magna Carta, the Black Death plague, and the Wars of the Roses weakened the monarchy and feudal system, while the Renaissance began to take hold in England by the late 15th century.
