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.
Archdiocese of Turku
After the Finnish War in 1809, Finland became a part of the Russian Empire as an autonomous grand duchy. In 1817 the Bishop was created Archbishop and became head of the Church in Finland, which thereupon became the state church of the grand duchy. In 1870, the church was detached from the state as a separate judicial entity. After Finland had gained independence in 1917, through the constitution of 1919 and the act on religious freedom of 1922 the Evangelical Lutheran Church of Finland became a national church of Finland (along with the Finnish Orthodox Church, which however did not get a constitutional position).
