Vikings (from Scandinavia) raid the British island monastery of Lindisfarne.
This marks the start of the Viking Age, particularly in the British Isles.
The Vikings also conquer and settle parts of France. Several generations later, in 1066 CE, the Norman (France–based) descendants of these Vikings, now speaking French and identifying themselves as French, effect the watershed Norman Conquest (of England) and become the ruling aristocracy of England. Thus the Vikings project across Europe and down through world history, albeit in morphed form.*
