That would be an interesting study, actually, to see what percentage of medieval kings died of old age (and not in their successor's dungeon). As a first order approximation, I've looked at the Wikipedia article "List of monarchs of the British Isles by cause of death"[0] (which covers more than just the medieval period), and counted this summary: Natural causes: 60 In battle: 15 Murdered, assassinated, executed: 17 Euthanised: 1 Other: 2 Accidental: 3 Unknown: 10 The "other" category seems to be cases where the monarch was effectively imprisoned and/or murdered, and I'll exclude the euthanised king as being controversial from the point of view of "violence". That leaves 107 deaths, of which 34 were violent (battle, murdered, assassinated, executed, imprisoned), giving a percentage of about 32%. I guess if you live like a king you have to be willing to die like one too.
