How would this kingdom orginization pan out? The Italian psuedo republic.

[Porsenna]

Was playing around with ideas earlier, and decided it might be cool to have a core territory of around 10-15 counties in Italy as personal holding under a single duchy title, and split the rest of the duchies into being republic level holdings under an electoral succession law.

What might be the consequences of this set up?

(To note, the inspiration is the set up of the Roman Empire - local republic civic traditions, but superseded by an Imperial authoritarian governance that largely left areas to their own devices unless there was some pressing reason to intervene/meddle directly.)

All dodges will get -30 to relations with you, in my experience it seems they cause a lot of headaches and I always try to get rid of them as soon as possible
I guess you'd be swimming in cash though? So you'd have mercenaries on your side at the very least.

Turning every thing to republics is difficult and hard to keep.
Playing as king of italy i have made republics all the 2 county coastal duchies in Italy.They are Italian and catholic so the elected will always be of my religion and culture.

But as you go farther away from you capital do not make republics.The distance in addition to the -30 opinion and the fact that rulers may be of the local culture is a sure way to instigate rebelions.

5 republics enough to provide you with 1500 gold/year which is more than enough

I've recently made an Italy with every coastal holding as a republic, you end up swimming in gold even on 25% and they tend to build up their holdings really fast. The main downside is castle holdings get totally left alone so you can barely raise any troops since the barons have no cities feeding them. I've just ended up hiring mercs to make up for the lack of troops.

Basically you end up with an inferior but larger army early game and hit 'late game' faster, but more civil wars (not by much however). If you swap your republics back into baronies later on then the barons will catch up on their holdings so as long as you don't go 'all the way' then its probably to your advantage.

...Scratch that, having a weak fort on the first level of your counties is a real pain. You end up shedding war score because they siege in like a month.

This might not be such a big deal in some mods. CK2+ has battles worth much more warscore (and I think there are some other mods where battles are a little more important) which takes some of the focus on occupying everything, so the strategy of high level cities and low level forts might be more workable in that situation.
