Finland is a Nordic country in Northern Europe. It shares land borders with Sweden to the northwest, Norway to the north, and Russia to the east, with the Gulf of Bothnia to the west and the Gulf of Finland across Estonia to the south. Finland covers an area of 338,455 square kilometres (130,678 sq mi) with a population of 5.6 million. Helsinki is the capital and largest city, forming a larger metropolitan area with the neighbouring cities of Espoo, Kauniainen, and Vantaa. The vast majority of the population are ethnic Finns. Finnish, alongside Swedish, are the official languages. Swedish is the native language of 5.2% of the population. Finland’s climate varies from humid continental in the south to the boreal in the north. The land cover is primarily a boreal forest biome, with more than 180,000 recorded lakes.
Finland was first inhabited around 9000 BC after the Last Glacial Period. The Stone Age introduced several different ceramic styles and cultures. The Bronze Age and Iron Age were characterized by extensive contacts with other cultures in Fennoscandia and the Baltic region. From the late 13th century, Finland gradually became an integral part of Sweden as a consequence of the Northern Crusades. In 1809, as a result of the Finnish War, Finland became part of the Russian Empire as the autonomous Grand Duchy of Finland, during which Finnish art flourished and the idea of independence began to take hold. In 1906, Finland became the first European state to grant universal suffrage, and the first in the world to give all adult citizens the right to run for public office. Nicholas II, the last Tsar of Russia, tried to russify Finland and terminate its political autonomy, but after the 1917 Russian Revolution, Finland declared independence from Russia. In 1918, the fledgling state was divided by the Finnish Civil War. During World War II, Finland fought the Soviet Union in the Winter War and the Continuation War, and Nazi Germany in the Lapland War. It subsequently lost parts of its territory, but maintained its independence.
Finland largely remained an agrarian country until the 1950s. After World War II, it rapidly industrialized and developed an advanced economy, while building an extensive welfare state based on the Nordic model; the country soon enjoyed widespread prosperity and a high per capita income. Finland joined the United Nations in 1955 and adopted an official policy of neutrality; it 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 the Eurozone at its inception in 1999. 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 ranked first in the World Human Capital,topped the Press Freedom Index, and was the most stable country in the world during 2011–2016, according to the Fragile States Index; it is second in the Global Gender Gap Report, and has ranked first in every annual World Happiness Report since 2018.
The earliest written appearance of the name Finland is thought to be on three runestones. Two of them have the inscription finlonti (U 582) and the third has the inscription finlandi (G 319) and dates back to the 13th century.
The name Suomi (Finnish for ‘Finland‘) has uncertain origins, but a common etymology with saame (the Sami, the native people of Lapland) and Häme (a province in the inland) has been suggested. In addition to the close relatives of Finnish (the Finnic languages), this name is also used in the Baltic languages Latvian (soms, Somija) and Lithuanian (suomis, Suomija), although these are later borrowings. An alternative hypothesis suggests the Proto-Indo-European word *(dʰ)ǵʰm-on- ‘human’ (Latin homo), being borrowed into Uralic as *ćoma.
In the earliest historical sources, from the 12th and 13th centuries, the term Finland refers to the coastal region around Turku. This region later became known as Finland Proper in distinction from the country name Finland. Finland became a common name for the whole country in a centuries-long process that started when the Catholic Church established a missionary diocese in 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 (1741–1743) caused Sweden to begin carrying out major efforts to defend its eastern half from Russia. These 18th-century experiences created a sense of a shared destiny that when put in conjunction with the unique Finnish language, led to the adoption of an expanded concept of Finland.
