A 4I ("four interest") faction's happiness is determined by factors that you can see in its tooltip in the Factions screen. Each faction meets every few years to decide whether or not it should actually do anything.

If a 4I faction is happy, it'll give you a bonus:
- The Court Faction may give you +10% maximum and minimum feudal levies for five years.
- The Prosperity Faction may give you +10% burgher taxes for five years.
- The Glory Faction may give you a lump sum of prestige (scaling with the number and rank of members).
- The Tradition Faction may give you a lump sum of piety (scaling with the number and rank of members).
- Any of the factions may give you a lump sum of cash (scaling with the number and rank of members).

If a 4I faction is angry, it'll make a demand on you--for lower obligations or crown authority, for your abdication, or merely for a county to be granted to one of its members. If you refuse its demands, it'll declare a civil war.

I can't get the tooltips to display at all.

I'm assuming that Prosperity likes a ruler who makes money, Tradition likes a pious ruler, Glory likes a prestigious one? And court likes, what?

I And court likes, what?

They care about offices for themselves.

 

[Tirion1987]

They also declare and join rebellions by event, apparently disregarding NAPs with their liege, who can't even call his allies into the fight. Not sure how much of this is intentional, but they are disproportionally more dangerous than traditional factions.

Council:
- The Glory Faction wants a member as your Marshal.
- The Tradition Faction wants a member as your Lord Spiritual.
- The Prosperity Faction wants a member as your Steward.
- The Court Faction wants a member in any council position.

Miscellany:
- The Glory Faction likes high prestige, wars, and tournaments.
- The Tradition Faction likes high piety, holy wars, and buying indulgences.
- The Prosperity Faction likes high cash reserves, peace, and summer fairs.
- The Court Faction likes feasts and tournaments.
(Yes, Glory and Prosperity are directly opposed. Prosperity wants at least five years of peace, while Glory will start getting annoyed after five years of peace.)

Any faction will be happier if:
- You have good relations with its members
- You grant titles to its members
- You keep obligations low
- You keep decadence low
