The earliest evidences of human settlement in Scandinavia are older than ten-thousand years. These early peoples developed a sophisticated living through hunting and fishing, with some evidence of agrarianism in present day Sweden. Not much is known about the two-hundred year period (c. 850 AD to 1050 AD) of the Vikings. Though only a modestly literate peoples, primary sources of information about them lie in archeological artifacts, as their written legacy is composed primarily of folklore. Therefore, little is known about their day-to-day lives. The few written accounts we do have come from their victims - England, Scotland and Ireland - which from 1018 to 1035 fell completely into Viking hands, as did large parts of France and Germany. The legendary seafaring adventurousness of these peoples belonged primarily to the Norwegian Vikings, whose settlements dotted the North Atlantic and included Iceland, the Orkney and Shetland Islands, Greenland and North America (though no permanent settlements were maintained in America). Viking conquests made extensive inroads by land as well. Conquests and trade routes to the east led to the eventual origin of the Russian State, and created links to Constantinople and the Mediterranean.
