Dissolution of toppled empires

[Tabris01]

In CM, tribal kingdoms are dissolved if the king looses any county he holds, instead of giving him one of one of his vassals. I find this to be a very good mechanic and think it could be included, in a modified form, for non tribal (and non feudal) empires.
For example, if the byzantine emperor holds only Constantinopel, which would be taken by an outside force, then the empire would start to crumble, as its administration just was beheaded - governors at its fringes or even in core territories would declare independence, while some might try and take over the throne. That happened, when the fourth crusade took Constantinopel and, for as short time, the ERE did not exsist as a political entity.
If the empire in question would be dissolved completely, I'd give ambitious rulers of kingdoms in de jure territory a claim on the de jure capital and most if not all of the de jure realm to make it possible to recreate the realm (like the kingdom of Nikea did after the 4th crusade).
THat mechanic would make it important to locate your capital and demesne away from your borders as an empire to not be easily destroyed and make large realms a bit more fragile.

Assuming the AI doesn't completely derp this up I'm fully in support of this idea.

How about an event that fires if your capital lies at your outer border (if you can check this) and would move it away, but only if you can revoke counties and would worsen relations with all your vassal by a certain amount. Also, your ruler would have to be capable (in my mind, a regent, even if he'd wanted for his empire to live, would have much of a harder time just collecting in a city), and, if one wanted to include some system about corruption (trait based, basicaly imperial decadence for highly centralized states, not only empires), not to be corrupt and not over his vassal limit.

Isn't this already partially in for some empires?

Dunno, but I think it should be limited for those with Imperial Administration in place. The feudal empire of our timeline (aka the HRE) never had a real capital, just a couple of more important and less important cities/holdings. If Aachen would have been taken by France, it never would have destroyed the Empire. A non-feudal one has all of its administration (even if decentralized) focused on the capital/the emperor and thus would not survive its fall at least without severe anarchy

To my knowledge whats inplace for an empire is once it goes below a certain holdings limit it dissolves. What Tabris is getting at is a secondary condition that if the Top liege ( could apply to kings and indy dukes) loses his last holding that his vassals decied if their lord can't even protect his own land how is he going to mine? Then up and become independent which would be great and frankly when I play as a vassal is exactly what I already do.
