Duchies of Costa Madora

The duchies of Costa Madora were the largest administrative divisions, governed by various dukes and duchesses.

As of 1916, Costa Madora does not recognize any duchies in its territory, except for the eleven duchies and a protectorate controlled by Geuvaria.

Early history
First Madorian duchies were established after the Revolutionary War, with the duchies of San Monica and Sautou directly ruled by the King.
