Sammanfattning: The study describes and explains the geographical, economic and political development in theUppsalaarea from the Bronze age to the Vendel Period. The landscape development was central. In the 1990s 14C datings made it possibly to create maps of this using GIS. The area contains forty thousand known constructions. When plotted they provide a picture of the area use. Together with information regarding the climate, pollen analyses and the external economic and political development, conditions was discerned. The key to the development was the position at the edge of the expanding mainland. The vicinity to earlier cultures, the River Dalälven and Åland together with possible contacts with southern cultures were significant.  In Periods III-IV led unrest to collaboration and the markings of territories. Cairns, hill forts, large stone settings and the great cult house in Håga were constructed. The Håga mound was probably an attempt to retain the old order. Towards the end of the Bronze Age, the collaboration withered and there are indications of border zones.   The boat-development around AD 0 expanded the contacts, mainly through long-distance travel for catching herring or seal. Although agriculture provided a basis for subsistence in the area and increased, it was not dominating. Fishing, hunting and gathering together played an equal role. The organized long-distance trade was limited. Helgö was a collaborative project to tie into international trading networks. After the Roman Period, Fjädrundaland’s predecessor was no longer an autonomous power. In the 6th century fighting occurred between the precursors to Attundaland and Tiundaland/Fjädrundaland. It ceased AD 600, and it seems likely that a federation was formed. Gamla Uppsala and the royal election site at Mora became the insignia. The federation formed a political impasse which with the economic situation may be the cause of the slow changes during the Vendel Period.
