12. The House of Windsor, which reigns in 16 countries, is based in what European nation?
From Quiz Modern Royal Families
Answer:
The United Kingdom
Queen Elizabeth II is a member of the House of Windsor. In addition to being the Queen of the United Kingdom of Great Britain and Northern Ireland, she is also the Queen of Canada, Australia, New Zealand, Jamaica, Barbados, the Bahamas, Grenada, Papua New Guinea, the Solomon Islands, Tuvalu, Saint Lucia, Saint Vincent and the Grenadines, Antigua and Barbuda, Belize, and Saint Kitts and Nevis.
The House of Windsor is a branch of the House of Saxe-Coburg-Gotha and was renamed the more "English sounding" House of Windsor during World War I due to the Germanic origins of the dynasty. Although the dynasty has only ruled the UK since 1901, Queen Elizabeth II is a descendant of English kings and queens going back well over 1000 years.
