Question: Who is the Longest Reigning British Monarch?
Answer: Queen Victoria is the longest reigning monarch of Britain, or any British kingdom. She took the throne on June 20, 1837 and ruled until January 22, 1901, a total of 63 years, 7 months and 3 days. Perhaps unusually for a monarch with such a long reign, Victoria was an adult throughout, taking the throne a few weeks after her eighteenth birthday. She died aged 81.
