 A more exact report dates from 8 June 793, when the cloister at Lindisfarne was pillaged by foreign seafarers.These raiders, whose expeditions extended well into the 9th century, were gradually followed by armies and settlers who brought a new culture and tradition markedly different from that of the prevalent Anglo-Saxon society.These enclaves rapidly expanded, and soon the Viking warriors were establishing areas of control to such an extent that they could reasonably be described as kingdoms.
