Just wondering if we were able to figure out an average length of reign for royalty in the middle ages. I'm looking mostly for either British or French, but any other data is welcome too. I also understand that it can vary depending on outside forces, but I'm wondering if anyonr wad able to calculate an average. Thank you!
I'm not sure that anyone has (I mean, it doesn't really tell you anything interesting about history, as far as I can see), but it wouldn't be particularly difficult. Pick your country (or countries), pick your start and end dates (so are you going to do all the French kings from Clovis, or just from Hugh Capet? Ending your English kings at Bosworth Field?) and then just apply the formula: add up all the reigns and divide by the number of kings. The regnal years are pretty easy to find.
Let us know how you get on!
