The realm factions screen ( F8 )

Factions are organized groups of vassals, united against their liege for a common purpose.

When a leader thinks the faction is powerful enough, they can issue an ultimatum to their liege. Unless the liege folds to the demands, this results in a civil war, where all faction members revolt together under a temporary title.

Each vassal can lead or join up to two Factions. If a faction leader dies, the most powerful remaining faction member automatically takes over as the new leader.

For vassal strategies, see Joining factions.
