The Pope - Does he tactically ex-communicate?

[cosminus]

Does anyone know if this reemergence is limited to former Papal provinces that either are rebel or are rebellion prone to begin with? Or will the pope reappear in ALL his former provinces every single time, thus making it a must keeping him alive just to save the lands he formerly owned?

When I played as HRE I had destroyed Pope and let empty the Papal states but not Rome. The Pope reemerged only in Rome and I withdrew from (Pope remain neutral to me), but not reemerged or attacked papal states even if empty (and ruin) and without governor. I presume Pope reemerge only in Rome.

Welcome, cosminus, to the .org

The Pope can reappear in any of his former provinces, though a reappearing faction usually only turns up in one province, any nearby rebellions in progress may choose to join them. Also if any of their former provinces are rebel at that time, then they will probably rejoin their faction. I have seen the Papacy reappear in the Papal States, and not Rome, many times.

Somehow the AI keeps track of a province that rebels away from it's faction by civil war or by the faction being wiped out. Those rebels in that province will remember which faction they belonged to and return to it.

Yep, that's been my experience as well. Also, given that a re-emerging faction is more likely to reappear in rebel provinces (although admittedly not always), I tend to make a habit of grabbing a dead faction's good provinces but leave alone the crappy/mediocre ones.

This strategy allows me to pick up some decent lands, while at the same time reducing the possibility of the faction reappearing in my territory later on. (I'm particularly fond of doing this to the Almos and leaving them stuck in Cyrenacia. )

As far as I know, the Papal reemergance is similar to any other faction reemergance, with one caveat. Usually, a province has to have loyalty issues to allow for a faction reemergance. I don't think the Papacy requires that, they can spring up in provinces with pretty solid loyalty. He does seem to favor provinces with fewer troops (smart cookie, that Pope), so pick one province you don't really want and pull out your troops. Let it rebel and let the bandits have it, and in 2 or 3 years, you'll be crusading happily again.
