Kingdom (Crusader Kings 2)

A kingdom is a realm of the fourth tier. Kingdoms are the second highest ranked playable realm. Kingdoms are composed of 1 or more duchies. The ruler of a kingdom is usually known as a king. Kings can be vassals of powerful emperor, but are more often independent rulers.

One of the counties in each kingdom is the capital and is normally held by the king of that kingdom. If that county's capital is a city or temple then the realm is a republic or theocracy respectively.
