In late December, US publication National Geographic published an article on the topic of slavery in the Viking Age, specifically commenting on "attempts to soften the raiders' reputation". The article claims that not enough focus has been placed on the role of slavery in Viking Age society and that that slavery was "vital to the Viking way of life". A quote from the article:
"The ancient reputation of Vikings as bloodthirsty raiders on cold northern seas has undergone a radical change in recent decades. A kinder, gentler, and more fashionable Viking emerged. ...
But our view of the Norse may be about to alter course again as scholars turn their gaze to a segment of Viking society that has long remained in the shadows."
Although Mimisbrunnr.info aims to be as objective as possible, the reader benefits from some commentary on some of these claims. Last I was aware, these comments regarding a 'kinder, gentler Viking Age' were in response to the monastery-derived image of vikings as a mindless "pagans", carrying the torch of earlier material, such as saint hagiographies, that portrayed Christianization as a sort of light bringer of culture to non-Christian peoples. The article also lacks discussion about how the notion and function of slavery differed from the modern era and how widespread slavery was during the period beyond Germanic Europe, particularly in Arabic society (in light of the mention of Ahmad ibn Fadlan).
In addition, the article makes rather speculative comments regarding polygamy during the Viking Age, for which there is no clear evidence.
Still, the article is worth a read, particularly regarding the discussion on grooved teeth that have been discovered in sites such as around what is now Lund, Sweden. For more, albeit brief, discussing regarding slavery during the Viking Age, see this National Museum of Denmark article.
