Iceland, a Nordic island nation, is defined by its dramatic landscape with volcanoes, geysers, hot springs and lava fields. Massive glaciers are protected in Vatnajökull and Snæfellsjökull national parks. Most of the population lives in the capital, Reykjavik, which runs on geothermal power and is home to the National and Saga museums, tracing Iceland’s Viking history. According to the ancient manuscript Landnámabók, the settlement of Iceland began in the year 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first permanent settler on the island. The climate of Iceland's coast is subarctic. The warm North Atlantic Current ensures generally higher annual temperatures than in most places of similar latitude in the world. Historically the population of Iceland were farmers that also fished cod throughout the Atlantic and often in the winter months when farming wasn’t possible. Today the fishing industry is still very important for the economy.
