County

The game also links it as Counties.

From the game's encyclopedia

A County is a Title one Tier below a Duchy and one above a Barony.

The Title includes the County Capital in the County, as well as De Jure rights to all the Baronies in the County.

Counties always have Holders because County Capitals cannot be destroyed.
