Pays de Gex
The Pays de Gex (literally, land of Gex) was a part of the County of Geneva during the High Middle Ages. It is notable for the fact that it changed hands between Switzerland, the Duchy of Savoy and France several times. The final decision about its political affiliation was made by the Treaty of Paris (1815), which split it between France and Switzerland. The French part is now the Arrondissement of Gex, while the Swiss part is now the northwestern part of the Canton of Geneva.
