The group was formed by students at Universidad Técnica del Estado at Santiago, Chile in 1967. In 1973 as they were on tour abroad, General Augusto Pinochet launched a coup d'etat and took power. Having heard of the numerous extra-judicial killings of many fellow artists by Chile's army, they took up residence in Italy, resulting in "the longest tour in history" for Inti-Illimani as they lived in de facto exile. They continued their efforts supporting Chilean democracy internationally; magnitizdat copies of their work continued to be widely distributed in Chile. In September 1988, days after they were no longer banned from Chile, they began touring Chile again, supporting the "No" side during the 1988 Chilean national plebiscite.
