I'm not talking about royal houses - I know those already exist. I'm thinking more along the lines of rulers by nation so if I want to see all the rulers of Scotland or Norway or Belgium there would be a page for each of those.
Perhaps this already exists but I couldn't find it.
[[Category: Monarchs of Scotland]]
[[Category: Monarchs of Norway]]
[[Category: Monarchs of Belgium]]
I think this is a missing link in the categorization process. What do you think?
