As we prepare for a coronation, now is a good time to test your knowledge of constitutional history by attempting to answer 300 questions across 30 categories, ranging from the early kings and queens of England and Scotland, through to today's royal family. Each section has 10 brain teasers, conundrums and anagrams on a particular subject, such as dynasties, religion or exile, combining illustrated and written questions, and finishing with a bonus 'Genius' question. An end section provides all the answers in comprehensive detail, so by the last page, you are fully prepared for the Carolean era. What do you already know - how much more can you learn? And just who is the longest-reigning English king?
