The Urban Farmer: Osteoarchaeological Analysis of Skeletons from Medieval Sigtuna Interpreted in a Socioeconomic Perspective

Doctoral Dissertation 2005, Revised 2014. At the end of the 10th century the first Swedish town Sigtuna was founded, which can be recognized as the beginning of urbanization in the Mälaren valley. Christianity was growing strong and the administrative power was probably concentrated to a few magnates gathered around a king. Though, Sigtuna played an important religious and political role, the time of prosperity was short and at the end of the 13th - early 14th century the importance of the town declined. The ambition with the present thesis has been to investigate the demography of the human skeletal material excavated in Sigtuna during the period 1983-1999. The skeletons from 528 individuals from six cemeteries dated to the end of 10th century to the early 16th century have been analysed. The material was subdivided into three chronological development phases synonymous with the establishment, the peak of prosperity and the decline of the town. Well-recognized anthropological techniques were applied together with a health index and chemical tests such as stable isotopes and trace elements. The main aims were to investigate: 1) differences in the material between contemporary inhabitants in Sigtuna, 2) differences in the material between the different chronological phases, 3) differences between the osteological results achieved from Sigtuna and results from other skeletal materials and 4) if the results can be connected to the indications of urbanization.
