Few questions about crusading

[Jan Zamoyski]

Is it possible to ask a Pope to call a crusade against a city controlled by the rebels? Or must it be owned by some "real" faction.

And a second question. The manual on p. 41 says "The greater the percentage of the population of taken to Heresy in a settlement, the more likely a Pope will approve a Crusade there". Does "Heresy" mean the percentage of the population being heretic on a city screen or simply being non-catholic?

At the beginning Jerusalem is rebel so I think the pope can call a crusade on anyone even rebels and heretic does mean the percentage of people being heretic its shown as a separate religion in if you look at the city browser thing.

Yeah, I've asked the pope to call several crusades and they can be called against excommunicated catholic factions, muslim factions and rebel factions - I think whether or not he'll call crusades against orthodox factions, dependt on their standing with the paplal states . . .
