The song was recorded immediately after the Carnation Revolution with the famous encore Agora o Povo Unido nunca mais será vencido (Now the People United will never more be defeated).
However, it was especially after Pinochet's September 1973 coup that the Chilean group Inti-Illimani made it famous around the world, after they published the song in the album La Nueva Canción Chilena.ĭuring the course of time the song has been used in various protests around the world against either left or right-wing dictatorships, most of which have no direct connection to the Chilean coup or Latin America. After the U.S.-backed SeptemChilean coup the song became the anthem of the Chilean resistance against the Pinochet regime, both within Chile and among the community of Chilean exiles and their political allies abroad. New Chilean Song music ensembles such as Vientos del Pueblo, Inti-illimani among others, made successful recordings of the song that filled the airways and the backgrounds of political rallies. The song was interpreted and recorded by a number of music groups shortly after it was composed and performed publicly by Sergio Ortega and Quilapayún. During Allende's campaign El pueblo unido jamás será vencido was a frequent slogan.
The song was initially composed as an anthem for the popular unity government, reflecting the spirit behind the mass mobilization of working-class people who in 1970 had elected Salvador Allende for the socialist transformation of Chile.
