A later wave of immigration was that of the Vikings, during the Early Middle Ages' Viking Age. During the Viking invasion of Britain, they set up their own kingdom in north-western England, which the Anglo-Saxons named the "Danelaw", after the Danes who lived there and controlled the land. Vikings from Scandinavia also controlled most of the islands which are now part of Scotland, including the Outer Hebrides, the Inner Hebrides, and the Northern Isles (the Shetland Islands and the Orkney Islands).After a long period when Anglo-Saxon England was split into various kingdoms, it was made into one kingdom by Æthelstan (Athelstan) in 945. In the 13th century, the lands of Wales were unified by force with England by the wars of Edward I of England ("Edward Longshanks").
