## Who they were

Claiming the throne promised to him, William invaded in 1066 and defeated and killed Harold at Hastings on 14 October. He crushed English resistance — the brutal Harrying of the North in 1069–70 — built castles across the country, replaced the English aristocracy with Normans, and ordered the Domesday Book survey of 1086.

## What they did

His conquest tied England to France, brought the French language to the elite and feudal landholding to the whole kingdom, and rebuilt the church under Norman bishops.

## Legacy

The Norman Conquest is a hinge of English history: it transformed the language, law, and ruling class, and every English monarch since traces descent from William. The date 1066 is the most famous in English history.
