Northern Catalonia

Northern Catalonia, North Catalonia or French Catalonia is the Catalan-speaking and cultural territory ceded to France by Spain through the signing of the Treaty of the Pyrenees in 1659 in exchange for France's effective renunciation to the protection over Catalonia in the context of the Reapers' War (1640–1659). The area corresponds roughly to the modern French département of the Pyrénées-Orientales which was historically part of the Principality of Catalonia since the old County of Barcelona, and remained part of it during the times of the Crown of Aragon and the Habsburg-ruled Monarchy of Spain, until they were separated and given to the Kingdom of France by the Crown of Spain.

The equivalent term in French, Catalogne du Nord, is used nowadays, although less often than the more politically neutral Roussillon (Catalan: Rosselló); Roussillon, though, historically did not include Vallespir, Conflent and Cerdagne (Cerdanya). The term Pays Catalan (País Català), "Catalan Country", is sometimes used.

Northern Catalonia forms a triangle between the Pyrenees to the south, the Corbières Massif to the north-west and the Mediterranean Sea to the east. The Roussillon plain in the east, by far the most populated area, is formed by the flood plains of the rivers Tech, Têt, and Agly (Catalan: Tec, Tet, Aglí). The districts of Vallespir and Conflent cover the upper valleys of the Tech and the Têt respectively. The massif of the Canigou (Catalan: Canigó), 2785 m, dominates much of the territory.

The climate is of the Mediterranean type, with hot, dry summers and winters which are relatively mild, at least on the Roussillon plain where snow is rare.

The city of Perpignan (Catalan: Perpinyà) accounts for over a quarter of the population, over one-third of its urban area is taken into account, and is the only major administrative and service center. Major road and rail links run north–south through Northern Catalonia between France and Spain, while a railway line also links Perpignan to Latour-de-Carol (Catalan: La Tor de Querol) via Prades (Catalan: Prada de Conflent or Prada).

Haute-Cerdagne (Catalan: Alta Cerdanya, English: Upper Cerdanya) is geographically distinct from the rest of Northern Catalonia, lying to the south of the Pyrenean watershed in the upper valley of the Segre. It is a mountainous and sparsely populated district, and includes the town of Llívia (pop. 1252 (2005)) which is an exclave of Spain.

The district lies on the most direct route between Toulouse (Occitan: Tolosa de Lengadoc) and Barcelona (via Foix and Ripoll), and a railway line still links the two cities via Latour-de-Carol (Catalan: La Tor de Querol).

Northern Catalonia formed part of the southern counties of the Frankish Empire (historiographically known as the Marca Hispanica), established by Charlemagne as a buffer territory against Al-Andalus forces. As such, it was divided into feudal counties, Rosselló, Vallespir, Conflent north of the Pyrenees and Cerdanya to the south. By the end of the ninth century, these counties had gained progressively independence from the Carolingian kings and operated as princely states (whose rulers nevertheless retained the title of count).
