The Communist Revolutionary League (Liga Comunista Revolucionaria, LCR) has been created in 1971 by members of the Catalan group Comunismo, an extension of the clandestine anti-Francoist organisation Frente de de Liberación Popular Español (FLP or also known as FELIPE). The LCR joined the 4th International and became the Spanish section. In 1972, several militants of the LCR created the Communist League (Liga Comunista). In 1973, the 7th Assembly of ETA-VI and the 3rd Congress of the LCR merged into one. The LCR started to be more and more implanted in the Basque country and in Nafarroa. In 1974, the Catalan Leninist-Bolshevik fraction joined the organisation and the LCR became LCR-ETA (VI). In 1976, the LCR-ETA (VI) changed its name to LCR while its Basque section formed the Liga Komunista Iraultzailea (LKI).
By the mid-1980s, the LCR started to collaborate with the Maoist Communist Movement (Movimiento Comunisto, MC) and merged in 1991 to create Izquierda Alternativa (Alternative Left). In 1993, the new organization failed. The ex-members of the LCR kept the name and but changed it for Espacio Alternativo (Alternative Space) in 1995 when they joined the coalition Izquierda Unida (United Left). More recently, in 2008, Espacio Alternativo became Izquierda Anticapitalista (Anti-Capitalist Left).
For the first time, former members of the LCR gathered their own archives into a single volume covering the entire history of that eclectic organisation. No less than 500 key documents are made available online to researchers.
