During World War I, King George V of England issued a proclamation which changed the name of Great Britain's royal family from Hanover to Windsor, and this decree was effective on July 17, 1917. The British royal family had German roots, dating back to 1714 when George I of Hanover took the throne. George I could barely speak English, and much of his reign was devoted to fighting wars back in his native Germany. The House of Hanover became the House of Saxe-Coburg-Gotha in 1840, after Queen Victoria married Prince Albert of Saxe-Coburg-Gotha, who was also a German. However, the royal household's name became something of an embarrassment after the outbreak of World War I, when Great Britain's most formidable enemy was the nation of Germany. The strong anti-German sentiment among the population prompted King George V to change the family's name. The name Windsor was taken from Windsor Castle, one of the royal family's principal residences. George V's successors were Edward VIII, George VI, and then Elizabeth II, who remains Britain's monarch as of the writing of this book. With some modifications, they have retained the name of Windsor ever since.
