This thesis deals with the image of the Vikings. I wish to investigate how this image came to being during the 19th and early 20th century and give examples of how the Viking age was approached archaeologically during this time period. In addition to this, I discuss the image of the Vikings in relation to concepts such as nationalism, Scandinavian identity and how we use history. The aim is to contribute to the discourse about ideology in relation to history. I wish to raise awareness about how we use history and how our evaluation of the past, in this case the Viking age, affects our perception of the past and the present. I have chosen three archaeological sites in order to exemplify how archaeologists have approached the Viking age, and how archaeology can be linked to ideology. These sites are Old Uppsala and Birka in Sweden, and Hedeby in present-day Germany. In addition to this, I also discuss what role the Viking age played in the 19th century world of ideas. I read and analyse publications on the topic from different time periods and contexts. The theories used are those of Stefan Bohman, Benedict Anderson and Lise Nordenborg Myhre on nationalism and its symbolism. The discussion is also based on Evert Baudou’s theories on archaeological interpretations, as well as the theoretical framework characteristic of the 19th century, culture-historical archaeology. The Viking age played an important part in shaping a Scandinavian identity, particularly in Sweden. The loss of Finland to Russia in 1809 created a need of a new identity. In the wake of this, as well as deepened relations to Norwegians and Danes, a new ideology called scandinavism was formed with the Viking age at centre. Later, the Iron Age was of significance when the German Nazi regime needed to legitimise their policies and ideology. The excavations at Hedeby mirror the Nazi ideology, but the Swedish sites have also proven to have connections to nationalism, both at the time of excavation but also in the form of interpretation. I base my analysis on the phenomena explanation, consolidation and rejection in order to establish how the past can be used in defining the present in relation to the past. I discuss how the past is used to define the present, ourselves and our society and how it is can be used in a nationalistic setting.
