In 1917, there was a radical change, when George V specifically adopted Windsor, not only as the name of the 'House' or dynasty, but also as the surname of his family. The family name was changed as a result of anti-German feeling during the First World War, and the name Windsor was adopted after the Castle of the same name. Herbert, Ian (9 September 2006).

It was therefore declared in the Privy Council that The Queen's descendants, other than those with the style of Royal Highness and the title of Prince/Princess, or female descendants who marry, would carry the name of Mountbatten-Windsor. Other commentators such as Mikal Gilmore and Todd Leopold have traced the inception of their socio-cultural impact earlier, interpreting even the Beatlemania period, particularly on their first visit to the US, as a key moment in the development of generational awareness. [101] [439] Referring to their appearance on the Ed Sullivan Show Leopold states: "In many ways, the Sullivan appearance marked the beginning of a cultural revolution ... The Beatles were like aliens dropped into the United States of 1964." [439] According to Gilmore:Whitburn, Joel (2003). Joel Whitburn's Top Pop Singles 1955–2002. Record Research. p.xxiii.

Geographically, the Viking Age covered Scandinavian lands (modern Denmark, Norway and Sweden), as well as territories under North Germanic dominance, mainly the Danelaw, including Scandinavian York, the administrative centre of the remains of the Kingdom of Northumbria, [69] parts of Mercia, and East Anglia. [70] Viking navigators opened the road to new lands to the north, west and east, resulting in the foundation of independent settlements in the Shetland, Orkney, and Faroe Islands; Iceland; Greenland; [71] and L'Anse aux Meadows, a short-lived settlement in Newfoundland, circa 1000. [72] The Greenland settlement was established around 980, during the Medieval Warm Period, and its demise by the mid-15th century may have been partly due to climate change. [73] The Viking Rurik dynasty took control of territories in Slavic and Finnic-dominated areas of Eastern Europe; they annexed Kiev in 882 to serve as the capital of the Kievan Rus'.
