The Co-Princes of Andorra are the two rulers of the Principality of Andorra, a tiny landlocked nation lying in the Pyrenees mountains between France and Spain. Founded in 1278 through a treaty between the Catalan Bishop of Urgell and the French Count of Foix, this unique monarchial arrangement has persisted through medieval times to the present day. Currently, the Bishop of Urgell and the President of France serve as Andorra's co-princes, following the transfer of the Count of Foix's claims to the Crown of France, and thence to the French Republic.
The Andorran principality has the unique distinction of being ruled by two sovereigns, one of whom (the French president) is the only monarch in the world to be elected by common citizens—though not by the citizens of Andorra, but rather those of France. He is also the only person to be a monarch and the head of state of a republic at the same time.
