The Normans were descendants of Vikings, who settled in the northwest France in the early 10th century AD. In 1066, led by William the Conqueror, they invaded England and conquered the resident Anglo-Saxons. Their villages were basically fortified settlements, consisting of earthwork-protected sites called motte (enditched mound) and bailey (courtyard) castles.
