In 1922, after the genocide of the Greek people of Minor Asia and Pontus and later by the population exchange between Greece and Turkey, many ethnic Greeks from Asia Minor and Pontus fled to Athens as a result of the Greco-Turkish War. They settled in poor neighborhoods and brought with them Rebetiko music, making it popular also in Greece, which became later the base for the Laïko music. Other forms of song popular today in Greece are elafrolaika, entechno, dimotika, and skyladika. Greece's most notable, and internationally famous, composers of Greek song, mainly of the entechno form, are Manos Hadjidakis and Mikis Theodorakis. Both composers have achieved fame abroad for their composition of film scores.
