Mikis Theodorakis was a Greek composer famous for writing the sirtaki for the film Zorba the Greek (1964). This piece of music is has become the embodiment of Greece, it is the most archetypal Greek music. More than that, it is definitely one of the most famous melodies of the 20th century, recognized — I think — by the majority of people in the world, wherever they live. On that last point, I have no evidence.

He was an opponent of the Greek junta, which like Salazar in Portugal and Franco in Spain, put Greece under the rule of a fascist military dictatorship until the mid 1970s.

I give also you the trailer of Z (1969), the music you hear is Theodorakis’s. Z is a work of political fiction, an indictment of the then-fascist Greece.
