Since 1066, there have been more than forty kings and queens of Britain (give or take a Cromwell, Scotland not included). They are a dazzling cast of characters, and we routinely debate over who deserves the title of greatest ruler in our long history. From William the Conqueror to Henry V, Elizabeth I, Victoria and latterly Elizabeth II – their lives tell the story of our nation.

But how exactly do you measure a monarch?

Measuring Monarchy provides a completely original outlook as to how to analyse British kings and queens and throws a revisionist Molotov cocktail into our historical thinking. It puts forward and explains the case for five comparative metrics for all UK monarchs: their professional standing, their popular standing with the public, their impact on public finances, how they conducted foreign policy and their preparations for succession.

Tim Hames casts a forensic eye over fifteen key kings and queens, determining whether their status has been overrated or underrated. What is revealed may surprise you, and some overlooked monarchs are returned to their rightful standing.
