About 9, years ago, at the end of the ice age, the ancestors of Finns moved here from the Urals Mountain and did not form a country. After 1157, Finland became the inherent territory of Sweden.

Iceland

Before Scandinavians and Celts immigrated to Iceland in the 9th and 1th centuries, Iceland was the last big uninhabited island in the world. Iceland established the world's earliest parliament in 93 AD (Icelandic: Al? Ingi), although this parliament did not run for long. Some written evidence shows that Irish monks once lived in Iceland before the arrival of northerners, but there is no archaeological evidence to prove this inference. Nordic people used this as a springboard to enter Greenland. Iceland remained independent for 3 years and was later ruled by Norway and Denmark. Iceland was a colony of the King of Norway before the partition of Denmark and the United Kingdom of Norway in 1814, and has since become a dependency of Denmark. In 1874, the Danish government granted Iceland limited autonomy. In 1918, Iceland further gained independence and sovereignty similar to that of a protectorate in internal affairs, while Denmark still retained power in foreign affairs and national defense. In 194, Nazi Germany occupied Denmark during World War II, and the allied forces occupied Iceland in the same year. The Danish king continued to rule legally until the establishment of Iceland in 1944. The new Republic is a member of NATO and signed an agreement with the United States to defend Iceland in 1949. According to this agreement, the United States set up a military base in Keflavík until the unilateral withdrawal of American troops at the end of September 26. So far, Iceland does not have its own army. In the decades after the war, Iceland's economy relied on fishing, and there were several conflicts with neighboring countries because of this biological resource, including the famous "Cod War" with Britain. In recent years, due to a large amount of investment in heavy industry, the economy has gradually diversified, aluminum smelting has developed, and the economic field has been continuously liberalized and privatized. Iceland became a member of the European Economic Area through the EEA, but never applied to join the European Union.
