He founded the "Little Orchestra of Athens" and the "Musical Society of Piraeus", gave many, many concerts all around Greece and abroad... and he naturally became involved in the politics of his home country. After the assassination of Gregoris Lambrakis in May 1963 he founded the "Lambrakis Democratic Youth" ("Lambrakidès") and was elected its president. Under Theodorakis's impetus, it started a vast cultural renaissance movement and became the greatest political organisation in Greece with more than 50.000 members. Following the 1964 elections, Theodorakis became a member of the Greek Parliament, associated with the left-wing party EDA. Because of his political ideas, the composer was black-listed by the cultural establishment; at the time of his biggest artistic glory, a large number of his songs were censored-before-studio or were not allowed on the radio stations.
