Exceeding the Duchy limit, Kingdom Titles and when to create or not create titles

crusader-kings-2

I've been playing a game a Munster and progressed from 1066 to 1128.

During this time I was not aware of the Duchy limit of 2 and the corresponding penalties of holding more than 2 Duchies can incur. As such I've been creating titles and keeping them to myself.

I've only concentrated on not exceeding my demesne limit.

I created various Duchies while expanding in Ireland and then went on to I create the Kingdom of Ireland itself, and through successful marriages I have inherited the kingdom of Brittany (The title of which I created as soon I could) and I am set to inherit The kingdom of Scotland as well through my Heir.

Then I will have 3 kingdom Titles and Numerous Duchy Titles.

My question or questions are… Should I not have created the Kingdom Title of Brittany? Is there any disadvantage to holding multiple kingdom titles? Will the kingdom of Brittany ever assimilate into the kingdom of Ireland now the title of king of Brittany has been created?

Also what are the benefits and disadvantages of holding so many Duchy titles? Should I have tried to not create them in the first place and should I have destroyed the Titles as I conquered them? Or should I give them up to my vassals?

The first disadvantage of having multiple highest tier titles (in your case, multiple kingdoms) is that it complicates succession. You'll want to make sure that all of your kingdom titles have their succession laws set up in such a way that you can insure that on your death all of them are going to your heir. The obvious problematic scenario is being on Gavelkind succession, which splits up your highest tier titles automatically. However, you can also have problems if, for instance, Ireland is on primogeniture succession and Brittany is on, say, Elective and the electors aren't voting for your eldest son.

The second disadvantage is that it creates more discontent in your realm. While holding those kingdom titles, any Dukes within the de jure territory of those kingdoms (except for those with the 'content' trait) will get a -20 relations modifier for 'Desires the Kingdom of x'. Ambitious dukes will get a further -50, since you posses something they desire. Note that this is also true of counts within the de jure territory of the duchies that you hold.

As for whether or not you should have created Brittany, it really kind of depends. Creating a kingdom is a good way to get claims, so if you needed the claims to take the territory in Brittany, then it could be a reasonable decision. Creating a kingdom 'just to have it' though when all the territory is already controlled has more cons than pros. You get a bit of extra prestige from holding the title, but the discontent it creates often isn't worth the trouble. Outside of getting easy claims, the only time I'd create a kingdom is if I need to to form an Empire.

There is a concept of 'de jure drift' which causes titles to 'assimilate' into others after they have been controlled for 100 years, but this only happens with a lower tier title drifting into a higher tier title. As such, Brittany will never assimilate into Ireland, but, should you form Britannia and become an Emperor, after 100 years the Kingdom of Brittany would drift into being de jure a part of Britannia.

The advantage of holding the duchies yourself is quite minor if you don't actually control the counties within the duchy yourself. Basically, the duchy you really want to hold is the duchy that contains your capital. All of the counties within this duchy get a bonus to levy size. Other than that, again if you don't own the counties themselves, you're only removing one person getting a 'cut' of the tax revenue and levies from the counties, but I would consider this not worth the -10 relations penalty (per duchy above two) that you're taking with all of your vassals.

I would immediately suggest giving all but two of the duchy titles away to vassals, and definitely choose counts who own land within the de jure territory of the duchy you're giving away. Keep your capital duchy, and work to get control of the counties within it (You should be able to plot to do this if your character doesn't have the 'content' trait. You'll have to get more creative otherwise) if you don't already have them. The second duchy to keep would be the one you control the most counties in, and, demense limit permitting, do the same thing as with the capital duchy. This way, you get the maximum levies and tax money out of the counties you control without taking any avoidable relations penalties.
