Socialist Organisation of National Liberation

Socialist Organisation of National Liberation (in Catalan: Organització Socialista d'Alliberament Nacional, OSAN) was a pro-Catalan independence radical socialist political party in the Catalan Countries. OSAN was formed by Pere Iu Baron i Xixell and his affiliates who split from Catalan Workers' Left (Catalan: Esquerra Catalana dels Treballadors, ECT) in 1977. The party was located in Northern Catalonia and maintained close relations with Catalan separatist organizations as well as Galician and Basque ones, specifically the Galician People's Union and Herri Batasuna.^[1]

OSAN maintained close contact with Socialist Party of National Liberation - Provisional, which was a radical, Provisional IRA-inspired split from Socialist Party of National Liberation. OSAN and PSAN-P then unified at the 1979 Congress in Rià (Conflent) and gave rise to Independentists of the Catalan Countries (Catalan: Independentistes dels Països Catalans, IPC). The organization published the magazine La Nova Falç. In 2000, the name of the organization was reused by reformist socialist Endavant–Organització Socialista d'Alliberament Nacional, an unconnected Catalan party.^[2]
