The Basque conflict, also known as the Spain–ETA conflict, was an armed and political conflict from 1959 to 2011 between Spain and the Basque National Liberation Movement, a group of social and political Basque organizations which sought independence from Spain and France. The movement was built around the separatist organization ETA, which had launched a campaign of attacks against Spanish administrations since 1959. ETA had been proscribed as a terrorist organization by the Spanish, British, French and American authorities at different moments. The conflict took place mostly on Spanish soil, although to a smaller degree it was also present in France, which was primarily used as a safe haven by ETA members. It was the longest running violent conflict in modern Western Europe. It has been sometimes referred to as "Europe's longest war".
