The Normans that invaded England in 1066 came from Normandy in Northern France. However, they were originally Vikings from Scandinavia. From the eighth century Vikings terrorized continental European coastlines with raids and plundering.
The Normans instead settled their conquests and cultivated land. Over time they assimilated into medieval European society, abandoned paganism, and upheld conventional Christian norms.
The Normans founded the duchy of Normandy and sent out expeditions of conquest and colonization to southern Italy and Sicily and to England, Wales, Scotland, and Ireland.
The Normans were originally pagan barbarian pirates from Denmark, Norway, and Iceland who began to make destructive plundering raids on European coastal settlements in the 8th century.
During the later 9th century their raids on the northern and western coastlands of France grew in scale and frequency, and the Vikings had secured a permanent foothold on Frankish soil in the valley of the lower Seine River by about 900. A Vikind named Rollo, who had already won a reputation as a great leader of Viking raiders in Scotland and Ireland, soon emerged as the outstanding personality among the new settlers.
