Clan governments can create new holdings and cadet branches and have access to the crown authority law; just like feudal governments, [[innovations]] are required to unlock higher crown authority. They also have access to the [[Casus belli#Conquest CBs|Conquest casus belli]], which can be used once in a lifetime to invade a realm, with higher-rank realms allowed at higher [[Resources#Level of Fame|levels of fame]].

Clan vassals provide taxes and levies based on their opinion of their liege. There is always a minimum of taxes and levies they will provide, which is determined by the liege's crown authority law. All vassals will want to be in an Alliance with their liege and will gain {{red|-15}} {{iconify|Opinion}} of their liege if they are not. The penalty is doubled for Powerful Vassals.
By default, a clan vassal will provide 15% of their taxes to their liege, and 30% of their levies. This amount is then adjusted with the vassal's opinion of their liege.
