Kingdom of Arles
The County of Savoy was detached "de jure" from the Kingdom of Arles by Charles IV, Holy Roman Emperor in 1361. It acquired the County of Nice in 1388, and in 1401 added the County of Geneva, the area of Geneva except for the city proper, which was ruled by its prince-bishop, nominally under the duke's rule: the bishops of Geneva, by unspoken agreement, came from the House of Savoy until 1533.
