Finland joined the OECD in 1969, the NATO Partnership for Peace in 1994, and finally the Eurozone at its inception, in 1999.
Finland was a relative latecomer to industrialisation, remaining a largely agrarian country until the 1950s.
Finland became a common name for the whole country in a centuries-long process that started when the Catholic Church established missionary diocese in Nousiainen in the northern part of the province of Suomi possibly sometime in the 12th century.
The devastation of Finland during the Great Northern War (1714–1721) and during the Russo-Swedish War (1741–43) caused Sweden to begin carrying out major efforts to defend its eastern half from Russia.
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. 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.
The earliest written appearance of the name Finland is thought to be on three runestones.
Cultures in Finland shared common features in pottery and also axes had similarities but local features existed.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.Finland is a Nordic country and, together with Scandinavia, is situated in the geographical region of Fennoscandia.Finland's population is 5.5 million (2016), and the majority of the population is concentrated in the southern region.
