Over the centuries, the Norwegian kingdom was alternately split apart and re-united. Between 1380 and 1814, Norway was in personal union with Denmark and then Sweden, but it maintained a large degree of autonomy. In 1814, Norway became an independent kingdom in personal union with Sweden but gained its full independence in 1905.
The current political structure of Norway is a constitutional monarchy with a parliamentary democracy. The King is the head of state, but the real power lies in the hands of the Prime Minister and the Parliament. Norway is a highly developed country with a strong social welfare system and a high standard of living. It is also a member of the United Nations, NATO, and the European Free Trade Association (EFTA).
