Old Norse: Language of the Vikings
Old Norse was the North Germanic language spoken in Scandinavia during the Viking Age. Old Norse developed from Proto-Norse by the 8th century and existed until the end of the 12th century. In the written form it is found as late as in the 15th century. After that it began to develop into modern North Germanic languages. It is to be noted that Old Norse was written with the Younger Futhark runes (Elder Futhark had been in use earlier for the Proto-Norse), and later with the Roman alphabet.
