It all comes down to your
reputation, which include; (aggresive) expansonism; assassinations; trsspasing without access; activly waging war without the concent of the majority (crusade) of your easy going factions, granting trade right or other diplomatic grants to your friends enemys, etc.
Therefor:
There is little use of expanding around easy going factions's "backyard", I prefere rebel regions abit further away. Bribe the pope to get the majority on your side, but don't push the envelope.
Mass assassinations of other easy going factions will give your leader dread and you become unpopulare.
Never tresspass on friendly regions without access. You heard me,
never.
Don't charge any faction out there, specially the populare factions (the pope factions, reliable factions, the same religion, your allys and easy going factions) You can however let them come to you, bite you till they get on the bad side of the pope -- then lunch a crusade

.
Never use any diplomatic engine with enemys. Including: christian - muslim, any religion - pagan, unpopulare factions, etc. No 'Trade rights', 'map information', give/take, no missions with them -- nothing. However, use the diplomatic engine
ALOT with your allys and enemys of your enemy (which are aso liked by the majority. Activly give away regions and spare money to keep their relations above 'Good'.
Did you get that?
PS: Easy going faction: Lets say you play England, then Flemish and Germany are an easy going factions.
