Vikings
Vikings were Norse seafarers, mainly speaking the Old Norse language, who, from the late 8th to late 11th centuries, raided and traded from their Northern European homelands across wide areas of Europe, and explored westwards to Iceland, Greenland, and Vinland. The term is also commonly extended in modern English and other vernaculars to the inhabitants of Norse home communities during what has become known as the Viking Age.

distinct culture and language, displaced much of the extant Roman influence of old.
On the European continent, East Francia developed into the Kingdom of Germany, which became the most important part of the Holy Roman Empire proclaimed by Otto I in 962 AD.
