History of Finland
The history of Finland begins around 9,000 BC during the end of the last glacial period. Stone Age cultures were Kunda, Comb Ceramic, Corded Ware, Kiukainen, and Pöljä cultures. The Finnish Bronze Age started in approximately 1,500 BC and the Iron Age started in 500 BC and lasted until 1,300 AD. Finnish Iron Age cultures can be separated into Finnish proper, Tavastian, and Karelian cultures. The earliest written sources mentioning Finland start to appear from the 12th century onwards when the Catholic Church started to gain a foothold in Southwest Finland.
History of Finland
By 5300 BC, pottery was present in Finland. The earliest samples belong to the Comb Ceramic Cultures, known for their distinctive decorating patterns. This marks the beginning of the neolithic period for Finland, although subsistence was still based on hunting and fishing. Extensive networks of exchange existed across Finland and northeastern Europe during the 5th millennium BC. For example, flint from Scandinavia and the Valdai Hills, amber from Scandinavia and the Baltic region, and slate from Scandinavia and Lake Onega found their way into Finnish archaeological sites, while asbestos and soap stone from Finland (e.g. the area of Saimaa) were found in other regions. Rock paintings — apparently related to shamanistic and totemistic belief systems — have been found, especially in Eastern Finland, e.g. Astuvansalmi.
Between 3500 and 2000 BC, monumental stone enclosures colloquially known as Giant's Churches () were constructed in the Ostrobothnia region. The purpose of the enclosures is unknown.
