There already is a similar question, but it has been closed as unclear. I will attempt to post a clear question instead.
- Time : 15th century
- Country: medieval Europe excluding Eastern Roman Empire, feel free to choose a country you can get data on.
- Setting: Urban, Peacetime
Background: in the 15th century, as argued in this video, the brigandine armour accompanied by helmet, mail and gambeson was already available to common soldiers or retinues. I am curious about the urban population and want to know what armour they possessed. To ask about chainmail might be a problem, because there are so many different pieces and we might get caught up in distinctions between hauberks and haubergeons. On the other hand, the helmet is perhaps the most indispensable piece of armour. To make it as definite as possible, I will ask:
What percentage of the urban 15th century population in Europe (see above about countries) owned any kind of helmet?
