What I have in mind is a quasi-federal monarchy such as the German Empire, where you had the Emperor and many kings and dukes throughout Germany. Were they all banned from being active in the politics at all? And if they were, would it be possible, in Germany or any other country, for royals to take an active role in their country's politics?
I ask all of this for this hypothetical scenario I had in mind, where, after more inconclusive WW1, with German monarchy not abolished, a non ruling dynasty royal becomes TTL equivalent of our favourite Austrian. But it doesn't necessairly need to be Germany at all, I'm just wondering if it ever happened and if it would be potentially possible?
