Etymology The term Països Catalans was first documented in 1876 in Historia del Derecho en Cataluña, Mallorca y Valencia. Código de las Costumbres de Tortosa, I (History of the Law in Catalonia, Majorca and Valencia. Code of the Customs of Tortosa, I) written by the Valencian Law historian Benvingut Oliver i Esteller. The term was both challenged and reinforced by the use of the term "Occitan Countries" from the Oficina de Relacions Meridionals (Office of Southern Relations) in Barcelona by 1933. Another proposal which enjoyed some popularity during the Renaixença was "Pàtria llemosina" (Limousine Fatherland), proposed by Víctor Balaguer as a federation of Catalan-speaking provinces; both these coinages were based on the theory that Catalan is a dialect of Occitan. None of these names reached widespread cultural usage and the term nearly vanished until it was rediscovered, redefined and put in the center of the identity cultural debate by Valencian writer Joan Fuster. In his book Nosaltres, els valencians (We, the Valencians, published in 1962) a new political interpretation of the concept was introduced; from the original, meaning roughly Catalan-speaking territories, Fuster developed a political inference closely associated to Catalan nationalism. This new approach would refer to the Catalan Countries as a more or less unitary nation with a shared culture which had been divided by the course of history, but which should logically be politically reunited. Fuster's preference for Països Catalans gained popularity, and previous unsuccessful proposals such as Comunitat Catalànica (Catalanic Community) or Bacàvia (after Balearics-Catalonia-Valencia) diminished in use. Today, the term is politically charged, and tends to be closely associated with Catalan nationalism and supporters of Catalan independence. The idea of uniting these territories in an independent state is supported by a number of political parties, ERC being the most important in terms of representation (32 members in
