The Basque National Liberation Movement (Spanish: Movimiento de Liberación Nacional Vasco, MLNV; Basque: Euskal Nazio Askapenerako Mugimendua, "ENAM") is an umbrella term that comprises all social, political and armed organizations orbiting around the ideas of the illegal armed organisation Euskadi Ta Askatasuna (ETA), proscribed internationally as a terrorist organisation. The wide variety of organizations and their different levels of belonging to this political space made this name very common in the 1980s and 1990s.
