French Cerdagne is the northern half of Cerdagne that became French at the Treaty of the Pyrenees in 1659, while the southern half remained Spanish (part of Catalonia). People in Catalonia often refer to French Cerdagne as Alta Cerdanya (i.e. "High Cerdagne"), but this name is not recognized in France. French Cerdagne has no particular status inside France, being just an area inside the département of Pyrénées-Orientales, contrary to the Spanish part of Cerdagne which is officially a Catalan comarca called Baixa Cerdanya (i.e. "Lower Cerdagne"). In France, people refer to the French part of Cerdagne as either Cerdagne française (i.e. "French Cerdagne"), or just Cerdagne.
