reintegrating the Roussillon and Cerdanya into the Principality. After the Treaty of the Pyrenees and cession to France The Treaty of the Pyrenees of 1659 ceded Northern Catalonia to France, where it became the province of Roussillon. The French provinces were abolished at the Revolution (Law of 1789-12-22), and Roussillon was joined with the district of Fenouillèdes (Occitan: Fenolheda) to form the département of the Pyrénées-Orientales, with Perpignan (Perpinyà) as its administrative centre. Present day The département of the Pyrénées-Orientales is divided into the arrondissements of Céret (Catalan: Ceret), Perpignan (Perpinyà) and Prades (Prada de Conflent), which are further divided into cantons and communes. Perpignan and sixteen surrounding communes are also associated in the Communauté d'agglomération Têt Méditerranée, created in 2001. Enclaved in the southwest of the département there is the Spanish (Catalonia) exclave of Llívia. As is common, the present-day arrondissements do not correspond to pre-Revolutionary boundaries. The arrondissement of Prades (Prada) covers the whole of Haute-Cerdagne (Alta Cerdanya) and Conflent (including Capcir), as well as about a third of Fenolheda (not part of the province of Roussillon). The arrondissement of Céret covers the whole of Vallespir but also the Côte Vermeille (Costa Vermella), which was historically under the control of the counts and veguers of Rosselló at Perpinyà (Perpignan). Catalan writers sometimes speak of the "comarques of Northern Catalonia". Unlike the autonomous community of Catalonia, these comarques have no administrative significance, although they usually correspond to a certain historical and geographical unity. A commonly used division is that of Joan Becat in his 1977 work Atles de Catalunya Nord, which follows closely the boundaries of the former vegueries except insofar as it promotes the former sotsvegueria of Capcir (177 km², pop. 1532 (1990)) to a full comarca. Politics The region is divided among those who support a union with France and those who support reuniting with Catalonia. A large majority of Northern Catalans oppose reuniting with Catalonia, but the Catalan Unity political party promotes the idea. The party has had some success since 1993, winning seats in municipal elections. It is now the most popular Catalan nationalist party in the region. Northern Catalans are proud of their Catalan heritage and have developed a "Northern Catalan" identity. However, unlike their Southern neighbors in Spanish Catalonia, the Catalan identity is not a nationalist movement in French Catalonia. According to a 2020 study, French Catalans experienced mass education in the second
