Foundation is correct.
Here is the complete and comprehensive list of restrictions on secession:
- You must be Duke.
- Your Duchy must contain at least one city.
- Your Duchy cannot contain all the cities in the realm.
- Your Duchy cannot contain the realm's capital.
- You must be in the city (within your Duchy) that you wish to become the new capital of your realm.
- This city must not have high independence/low control.
- You must have been in both your duchy and realm for at least 2 weeks.
- You must have at least 6 hours available.
- You cannot already be the ruler of your realm.
- You cannot be in an NPC realm (pretty much moot nowadays, save for bugs).
- You cannot have a family member who is already a ruler on the continent.
Okay, is there a reason that one can change allegiance while they have the capital of the realm within their duchy, but they can't secede? This seems to be an outdated holdover from the old-estate system. The new estate system mainly the Duke/Margrave separation mechanic seems to make this point somewhat antiquated.
It makes sense to me that a Duke can't secede if his ONLY city is the capital of the realm. However, if he chooses to secede and create a new realm while having more than one city, and he makes the capital of the new realm a different capital than the old one you have a completely different set of circumstances than ever seen before.
I guess I'm confused what is trying to be restricted here. Every single other restriction I can think of a reason for it to be in place, but this one baffles me. What is different about a Duke seceding a three city duchy(in a 4 city or more realm) and a duke transferring the allegiance of his three city duchy to another realm, (perhaps a one city realm).
P.S. Thank you everyone for the responses so far. Very helpful.
