Norman Conquest and Angevin Empire
1066 is probably the most famous date in English history - when William of Normandy defeated Harold Godwinson at the Battle of Hastings and changed England forever. But this story starts with a succession crisis when Edward the Confessor died childless.
Three men claimed the throne: Harold Godwinson (supported by the English nobles), William of Normandy (claiming both Harold and Edward had promised him the crown), and Harald Hardrada (representing Viking claims). Harold brilliantly defeated the Vikings at Stamford Bridge in September, then marched south to face William.
William's victory created the Norman Kingdom, introducing French customs, language, and architecture. Norman barons received English land in exchange for loyalty, built hundreds of castles, and French became the language of power. The famous Domesday Book recorded this massive land redistribution.
Did You Know?: The Norman conquest created England's class system that influenced society for nearly 1,000 years.
Henry II expanded this into the Angevin Empire by marrying Eleanor of Aquitaine in 1152, controlling territory from Scotland to the Pyrenees. However, his son John's military failures led to losing most French territories and facing the barons' rebellion, resulting in Magna Carta in 1215 - limiting royal power and establishing basic legal rights that still influence law today.
