Zeca is among the most influential folk and political musicians in Portuguese history. He became an icon among Portuguese left-wing activists due to the role of his music in the resistance against the dictatorial regime of Oliveira Salazar that triumphed in 1974, with the pro-democratic leftist military coup of the Carnation Revolution. In the ensuing revolutionary process, Zeca was a very active musician and continued composing political and folk songs, often criticizing the post-revolutionary changes. Years after his death, Zeca Afonso is still widely listened to, not only in Portugal, but also abroad.
