Oceanic climateAn oceanic climate, also known as a marine climate, is the temperate climate sub-type in Köppen classification represented as Cfb, typical of west coasts in higher middle latitudes of continents, generally featuring cool summers and mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 45 and 63 latitude, most notably in northwestern Europe, northwestern America, as well as New Zealand.
Christianization of ScandinaviaThe Christianization of Scandinavia, as well as other Nordic countries and the Baltic countries, took place between the 8th and the 12th centuries. The realms of Denmark, Norway and Sweden established their own archdioceses, responsible directly to the pope, in 1104, 1154 and 1164, respectively. The conversion to Christianity of the Scandinavian people required more time, since it took additional efforts to establish a network of churches. The earliest signs of Christianization were in the 830s with Ansgar's construction of churches in Birka and Hedeby.
NorsemenThe Norsemen (or Norse people) were a North Germanic ethnolinguistic group of the Early Middle Ages, during which they spoke the Old Norse language. The language belongs to the North Germanic branch of the Indo-European languages and is the predecessor of the modern Germanic languages of Scandinavia. During the late eighth century, Scandinavians embarked on a large-scale expansion in all directions, giving rise to the Viking Age. In English-language scholarship since the 19th century, Norse seafaring traders, settlers and warriors have commonly been referred to as Vikings.
