House of Windsor

House of Windsor, very rarely called House of Mountbatten-Windsor, is the name used by the Royal Family of the United Kingdom of Great Britain and Northern Ireland since 1917. The dynasty had reigned since 1714 under the names House of Hanover (1714-1901) and House of Saxe-Coburg-Gotha (1901-1917), before abandoning these unpopular German names during World War I in favor of the name of a British castle. The monarchs who have used the Windsor title are George V, Edward VIII, George VI, and Elizabeth II.
