The Viking maritime expansion from Scandinavia (Denmark, Norway, and Sweden) marks one of the swiftest and most far-flung cultural transformations in global history. During this time (c. 750 to 1050 CE), Viking sailors reached Greenland, North America, and large parts of western Eurasia, and left a legacy that persists today. To understand the genetic structure and influence of the Viking expansion, we sequenced the genomes of 442 ancient humans from across Europe and Greenland ranging from the Bronze Age (c. 2400 BCE) to the early Modern period (c. 1600 CE), with particular emphasis on the Viking Age. We find that the period preceding the Viking Age was accompanied by foreign gene flow into Scandinavia from the south and east: spreading from Denmark and eastern Sweden to the rest of Scandinavia. Despite the close linguistic similarities of modern Scandinavian languages, we observe genetic structure within Scandinavia, suggesting that regional population differences were already present 1,000 years ago. We find evidence for a majority of Danish Viking presence in England, Swedish Viking presence in the Baltic, and Norwegian Viking presence in Ireland, Iceland, and Greenland. Additionally, we see substantial foreign European ancestry entering Scandinavia during the Viking Age. We also find that several of the members of the only archaeologically well-attested Viking expedition were close family members. By comparing Viking Scandinavian genomes with present-day Scandinavian genomes, we find that pigmentation-associated loci have undergone strong population differentiation during the last millennia. Finally, we are able to trace the allele frequency dynamics of positively selected loci with unprecedented detail, including the lactase persistence allele and various alleles associated with the immune response. We conclude that the Viking diaspora was characterized by substantial foreign engagement: distinct Viking populations influenced the genomic makeup of different regions of Europe, while Scandinavia also experienced increased contact with the rest of the continent.

Did towns return to early medieval
Walrus-tusk ivory and walrus-hide rope were highly desired goods in Viking Age northwest Europe. New finds of walrus bone and ivory in early Viking Age contexts in Iceland are concentrated in the southwest , and suggest extensive exploitation of nearby walrus for meat, hide and ivory during the first century of settlement. In Greenland, archaeofauna suggest a very different specialized long-distance hunting of the much larger walrus populations in the Disko Bay area that brought mainly ivory to the settlement areas and eventually to European markets. New lead isotopic analysis of archaeological walrus ivory and bone from Greenland and Iceland offers a tool for identifying possible source regions of walrus ivory during the early Middle Ages. This opens possibilities for assessing the development and relative importance of hunting grounds from the point of view of exported products.
This paper presents the results of the use of a minimally destructive biomolecular technique to explore the resource networks behind one of the first specialized urban crafts in early mediaeval northern Europe: the manufacture of composite combs of deer antler. The research incorporates the largest application of species identification by peptide mass fingerprinting (ZooMS) to a mediaeval artefact assemblage: specifically to collections of antler combs, comb manufacturing waste, and raw antler from Ribe, Aarhus, and Aggersborg. It documents the early use of reindeer (Rangifer tarandus) antler, from the 780s AD at the latest, presenting the earliest unambiguous evidence for exchange-links between urban markets in the southern North Sea region and the Scandinavian Peninsula. The results demonstrate that the common conceptual distinction between urban hinterlands and long-distance trade conceals a vital continuity. Long-range networks were vital to urban activities from the first appearance of towns in this part of the world, preceding the historically documented maritime expansion of the Viking Age. We consequently suggest that urbanism is more appropriately defined and researched in terms of network dynamics than as a function of circumscribed catchment areas or hinterlands.
