  This book discusses the 1st-11th century developments that led to the formation of the three Scandinavian kingdoms in the Viking Age. Wide-ranging studies of communication routes, regional identities, judicial territories, and royal sites and graves trace a complex trajectory of rulership in these pagan Germanic societies. In the fi nal section, new light is shed on the pinnacle and demise of the Norwegian kingdom in the 13th-14th centuries. The book seeks to revitalise the somewhat stagnant scholarly debate on Germanic rulership in the first millennium AD. A series of comprehensive chapters combines literary evidence on Scandinavia’s polities, kings, and other rulers with archaeological, documentary, toponymical, and linguistic evidence. The picture that emerges is one of surprisingly stable rulership institutions, sites, and myths, while control of them was contested between individuals, dynasties, and polities. While in the early centuries, Scandinavia was integrated in Germanic Europe, profound societal and cultural changes in 6th-century Scandinavia and the Christianisation of Continental and English kingdoms set northern kingship on a different path. The pagan heroic warrior ethos, essential to kingship, was developed and refined; only to recur overseas embodied in 9th–10th-century Vikings. Three chapters on a hitherto unknown masonry royal manor at Avaldsnes in western Norway, excavated 2017, concludes this volume with discussions of the late-medieval peak of Norwegian kingship and it’s eventual downfall in the late 14th century. This book’s discussions and results are relevant to all scholars and students of 1st-millenium Germanic kingship, polities, and societies.

  The Avaldsnes Royal Manor project explores early kingship in Northern Europe, spanning the period c. AD–1320 AD. The principal case is the Norwegian kingdom and the core site is Avaldsnes near Haugesund, Western Norway. 9th–10th century skaldic poems as well as 13th century sagas implies that Avaldsnes was the principal Viking Age royal manor. The site has produced numerous exquisite gravefinds from the Roman period onwards. Among them are the third century Flaghaug grave and two ship graves from the late 8th century. Also, the Oseberg ship, excavated near Oslo, is now proven to have been built c. 820 near Avaldsnes. The Museum of Cultural History, University of Oslo, excavated the Avaldsnes settlement in 2011–12. A team of 23 scholars from prominent academic institutions, including the University of Cambridge and University College London, participate in the research. This first of two volumes contains their results regarding the manor and its setting on the island of Kǫrmt by the Norðvegr, the sheltered sailing route along the West-Scandinavian coast. Together, the chapters produce a detailed 1000-years’ history of a complex central-place area, its monuments and buildings, its activities and functions, its blooming and fading, and eventually its downfall in the 14th century.

  The need for a joint Nordic platform for archaeological theory has recently been reflected upon on the pages of this journal. Is there a need for a Nordic TAG? Are there issues that pertain to a particularly Nordic theoretical debate? And if so, why is it that this seemingly ideal venue tends towards hibernation every now and then? These questions will be discussed here, though not fully answered. Most importantly, however, with this short comment we are happy to inform you that the Nordic TAG will be returning this coming spring. Hosted jointly by the Department of Archaeology, Conservation and History and the Museum of Cultural History, both part of the University of Oslo, the aim is set for lively conversations and constructive arguments in late April 2022. We hope to see you there!

  Avaldsnes, on the island of Karmøy in southwest Norway is the point of departure in this thesis. The richly furnished Flaghaug burial demonstrates the socio-political centrality of Avaldsnes in the Early Iron Age. In the late Viking and early Middle ages, centrality is testified in saga literature and documentary sources referring to Avaldsnes as a royal farm. The characteristics of Avaldsnes as an elite settlement was further investigated through excavations in 2011-12 by the Avaldsnes Royal Manor project led by Professor Dagfinn Skre. The recent excavation data form the basis for a discussion of a detailed chronology of Avaldsnes through a collection of thematic articles targeting various aspects of the settlement. Combined, these articles investigate how power was articulated through material culture in the period AD 200 — 1000.Furthermore, the formation of sub-regional groups and networks were addressed through a study of burials with brooches in the surrounding landscapes. While previous research on socio-political structures and identity negotiated through material culture identified mainly regional or super-regional structures, this thesis introduces an intra-regional scale. The spatial and temporal structure of the analysis resulted in the establishment of a sub-regional diachrony. Interrelation between these changing sub-regions over time was addressed, and related to processes of sociopolitical centralisation/fragmentation and emerging kingship. By bringing together the newly established chronology of Avaldsnes and the trajectories of the sub-regions in the surrounding landscapes, this thesis provides Avaldsnes with a new socio-political context and enables a discussion ofthe link between burial practices and socio-political structure. It is argued that burials in different sub-regions communicate different principles and ideals and that these differences or local particularities become a form of politicised identity.
