Finland (/ ( listen); Finnish: Suomi [suo̯mi] ( listen); Swedish: Finland [ˈfɪnland]), officially the Republic of Finland (Finnish: Suomen tasavalta, Swedish: Republiken Finland) is a sovereign state in Northern Europe. The country has land borders with Sweden to the northwest, Norway to the north, and Russia to the east. To the south is the Gulf of Finland with Estonia on the opposite side. Finland is a Nordic country and, together with Scandinavia, is situated in the geographical region of Fennoscandia.
Finland's population is 5.5 million (2017), and the majority of the population is concentrated in the southern region. 88.7% of the population is Finnish and speaks Finnish, a Uralic language unrelated to the Scandinavian languages; next come the Finland-Swedes (5.3%). Finland is the eighth-largest country in Europe and the most sparsely populated country in the European Union. It is a parliamentary republic with a central government based in the capital city of Helsinki, local governments in 311 municipalities, and one autonomous region, the Åland Islands. Over 1.4 million people live in the Greater Helsinki metropolitan area, which produces one third of the country's GDP.
Finland was inhabited when the last ice age ended, approximately 9000 BCE. The first settlers left behind artifacts that present characteristics shared with those found in Estonia, Russia, and Norway. The earliest people were hunter-gatherers, using stone tools. The first pottery appeared in 5200 BCE, when the Comb Ceramic culture was introduced. The arrival of the Corded Ware culture in southern coastal Finland between 3000 and 2500 BCE may have coincided with the start of agriculture. The Bronze Age and Iron Age were characterised by extensive contacts with other cultures in the Fennoscandian and Baltic regions and the sedentary farming inhabitation increased towards the end of Iron Age. At the time Finland had three main cultural areas, Southwest Finland, Tavastia and Karelia, as reflected in contemporary jewellery.
From the late 13th century, Finland gradually became an integral part of Sweden through the crusades and the Swedish part-colonisation of coastal Finland, a legacy reflected in the prevalence of the Swedish language and its official status. In 1809, Finland was incorporated into the Russian Empire as the autonomous Grand Duchy of Finland. In 1906, Finland became the first European state to grant all adult citizens the right to vote, and the first in the world to give all adult citizens the right to run for public office.
Following the 1917 Russian Revolution, Finland declared itself independent. In 1918, the fledgling state was divided by civil war, with the Bolshevik-leaning Red Guard supported by the equally new Soviet Russia, fighting the White Guard, supported by the German Empire. After a brief attempt to establish a kingdom, the country became a republic. During World War II, the Soviet Union sought repeatedly to occupy Finland, with Finland losing parts of Karelia, Salla, Kuusamo, Petsamo and some islands, but retaining independence.
Finland joined the United Nations in 1955 and established an official policy of neutrality. The Finno-Soviet Treaty of 1948 gave the Soviet Union some leverage in Finnish domestic politics during the Cold War era. Finland joined the OECD in 1969, the NATO Partnership for Peace in 1994, the European Union in 1995, the Euro-Atlantic Partnership Council in 1997, and finally the Eurozone at its inception, in 1999.
Finland was a relative latecomer to industrialisation, remaining a largely agrarian country until the 1950s. After World War II, the Soviet Union demanded war reparations from Finland not only in money but also in material, such as ships and machinery. This forced Finland to industrialise. It rapidly developed an advanced economy while building an extensive welfare state based on the Nordic model, resulting in widespread prosperity and one of the highest per capita incomes in the world. Finland is a top performer in numerous metrics of national performance, including education, economic competitiveness, civil liberties, quality of life, and human development. In 2015, Finland was ranked first in the World Human Capital and the Press Freedom Index and as the most stable country in the world during 2011–2016 in the Fragile States Index, and second in the Global Gender Gap Report. A large majority of Finns are members of the Evangelical Lutheran Church, and freedom of religion is guaranteed under the Finnish Constitution.
