Add AI weights to Catholic Countries to Discourage Annexation of the Papacy

[opaque minnow]

All Catholic countries should have a heavy weights discouraging the AI from attempting to annex any locations in the traditional territory of the Papal States, or at least for Latium itself. This weight shouldn’t apply to any locations that isn’t traditionally associated with the Papacy, so nations can fight back against a Borgia like hyper aggressive Papacy. This weight should disappear by the fourth or fifth era. This weight shouldn’t apply to any non-Catholic counties.

Should a Catholic country find itself in possession of traditional Papal Territory it should be weighted to return it to the Papacy until the 4th or 5th era.

Should a Catholic country refuse to return traditional Papal territory, (or at least Latium) the nation should face excommunication.

If a non-Catholic country annex Rome, a crusader to retake Rome for the Papacy should trigger immediately. (A similar Jihad response should occur if Mecca or Medina is taken by a non-Muslim country)

These are my humble suggestions since the Catholic world should treat the Papacy special, not just like some random nation, at least not for most of the game.

I disagree with your method

It should be that catholic countries are weighted against annexing the papal states fully

an Italian country, should absolutely try and take latium back from the papal states

while France will obvioulsy try to take back avignon

and alternative solution would be to allow catholic countries to turn the papacy into a building based country if they annex it (to represent the vatican)

That would be an interesting solution. A special Vaticano building being in Rome that always exists and is always control by the Papacy. Should the papacy loose all its locations then it becomes a building based country. It would represent Catholic nations claiming temporal power of Rome without a usurpation of the spiritual power of Rome.

There could probably be special conditions to destroy the building too

A Holy See building, then opens up a whole can of worms for stuff like caesaropapism and right of appointment of the Pope.
