Bronze Age
The history of Sweden between 1700 BC and 501 BC
Sweden's southern third was part of the stock-keeping and agricultural Nordic Bronze Age Culture's area, most of it being peripheral to the culture's Danish centre. The period began in c. 1700 BC with the start of bronze importation; first from Ireland and then increasingly from central Europe. Copper mining was never tried locally during this period, and Scandinavia has no tin deposits, so all metal had to be imported though it was largely cast into local designs on arrival. Iron production began locally toward the period's end, apparently as a kind of trade secret among bronze casters: iron was almost exclusively used for tools to make bronze objects.
The Nordic Bronze Age was entirely pre-urban, with people living in hamlets and on farmsteads with single-story wooden long-houses. Geological and topographical conditions were similar to those of today, but the climate was milder.
Rich individual burials attest to increased social stratification in the Early Bronze Age. A correlation between the amount of bronze in burials and the health status of the deceased's bones shows that status was inherited. Battle-worn weapons show that the period was warlike. The elite most likely built its position on control of trade. The period's abundant rock carvings largely portray long rowing ships: these images appear to allude both to trade voyages and to mythological concepts. Areas with rich bronze finds and areas with rich rock art occur separately, suggesting that the latter may represent an affordable alternative to the former.
Bronze Age religion as depicted in rock art centres upon the sun, fertility and public ritual. Wetland sacrifices played an important role. The later part of the period after about 1100 BC shows many changes: cremation replaced inhumation in burials, burial investment declined sharply and jewellery replaced weaponry as the main type of sacrificial goods.
