The Bronze Age began around 1800 BC and involved innovations such as ploughing fields with [[ard (plough)|ards]], permanent farms with houses and yards, especially in the fertile areas around the Oslofjord, [[Trondheimsfjord]], [[Mjøsa]] and [[Jæren]].<ref name="Stenersen: 11" /> Some yields were so high that it allowed farmers to trade furs and skins for luxury items, especially with [[Jutland]].<ref name="s12">Stenersen: 12</ref> About 1000 BC, speakers of [[Uralic languages]] arrived in the north and assimilated with the indigenous population, becoming the [[Sami people]].<ref name="s10" /> According to Ante Aikio<ref>{{citation |last=Aikio |first=Ante |contribution=An essay on substrate studies and the origin of Saami |editor1-last=Hyvärinen |editor1-first=Irma |editor2-last=Kallio |editor2-first=Petri |editor3-last=Korhonen |editor3-first=Jarmo |title=Etymologie, Entlehnungen und Entwicklungen: Festschrift für Jorma Koivulehto zum 70.

A climate shift with colder weather started about 500 BC. The forests, which had previously consisted of [[elm]], [[tilia|lime]], [[fraxinus|ash]] and [[oak]], were replaced with [[birch]], [[pine]] and [[spruce]]. The climate changes also meant that farmers started building more solid structures for shelter. Knowledge of [[Ferrous metallurgy|ironworking]] was introduced from the [[Celts]], resulting in better weapons and tools.<ref name="s12" />
