Nomadic
Nomadic is a government type.
Nomadic government is found in the steppes of central Asia in which the realm is not focused on keeping and holding baronies, but instead moves around in search of new grazing land for horses and other livestock. The only succession law is the Nomad succession law, in which the male relative (uncle, brother, son or nephew) of the same culture with the most prestige inherits.
Whilst nomads can have ordinary vassals, like in the Feudal system, most internal politics is centered around management of the other powerful clans in the realm, who can often rival or outshine the liege in terms of power. Nomadic rulers can only hold the Nomadic capital (a special holding type that is only available to Nomads and exists only in their capital province) without penalty, and gain benefits from having empty land in their realm (increasing their manpower and population, which they use to recruit troops for their horde).
