Iceland is a Nordic European island country situated at the confluence of the North Atlantic and Arctic Oceans, on the Mid-Atlantic Ridge. The country has a population of about 320,000 and a total area of 103,000 km (40,000 sq mi), which makes it the most sparsely populated country in Europe. The capital and largest city is Reykjavík, with the surrounding areas in the southwestern region of the country being home to two-thirds of the country's population. Iceland is volcanically and geologically active. The interior consists mainly of a plateau characterised by sand and lava fields, mountains and glaciers, while many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate despite a high latitude just outside the Arctic Circle.
According to Landnámabók, the settlement of Iceland began in AD 874 when the chieftain Ingólfur Arnarson became the first permanent Norse settler on the island. Others had visited the island earlier and stayed over winter. Over the following centuries, Norsemen settled Iceland, bringing with them thralls (slaves) of Gaelic origin. From 1262 to 1918, Iceland was part of the Norwegian and later the Danish monarchies. The country became independent in 1918 and a republic was declared in 1944. Until the 20th century, the Icelandic population relied largely on fishing and agriculture, and the country was one of the poorest and least developed in the world. Industrialisation of the fisheries and aid from the Marshall Plan brought prosperity in the years after World War II, and by the 1990s Iceland was one of the world's wealthiest countries. In 1994, Iceland became party to the European Economic Area, which made it possible for the economy to diversify into economic and financial services.
Iceland has a free-market economy with relatively low corporate taxes compared to other OECD countries, while maintaining a Nordic welfare system that provides universal health care
