Between 1935 and 1975, the period of Franco's régime, the use of Basque was strictly prohibited, and thus language decline begun to occur as well. However, following the death of Franco, many Basque nationalists demanded that the Basque language be recognized. One of these groups was Euskadi Ta Askatasun (ETA). ETA had initially begun as a nonviolent group to promote Basque language and culture. However, when its demands were not met, it turned violent and evolved into violent separatist groups. Today, ETA's demands for a separate state stem partially from the problem of perceived linguistic discrimination. However, ETA called a permanent cease-fire in October 2011.
