From around A.D. 800 to the 11th century, a vast number of Scandinavians left their homelands to seek their fortunes elsewhere. These seafaring warriors--known collectively as Vikings or Norsemen ("Northmen")--began by raiding coastal sites, especially undefended monasteries, in the British Isles. Over the next three centuries, they would leave their mark as pirates, raiders, traders and settlers on much of Britain and the European continent, as well as parts of modern-day Russia, Iceland, Greenland and Newfoundland.
Shows set in a long gone period of time. Even if that time happens to be the 80's. Basically everything not taking place in the present of the time of filming.
