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.
Finland Swedish
From the 16th century, Swedish was the main language of jurisdiction, administration and higher education in Finland (which was then a part of Sweden), but the majority of the population in the Finnish inland spoke Finnish outside of these sectors of society, i.e. in normal, daily life. In 1809, when Finland was conquered by the Russian Empire and became an autonomous Grand Duchy, Swedish remained the only official language. In 1863, both Finnish and Swedish became official languages with equal status, and by the time of Finland's independence in 1917, after a Finnicization campaign by the Fennoman movement, Finnish clearly dominated in government and society.
