Members were drawn from the committee for re-establishment of democracy in Greece, and fighters from Lyssaridis's group during the 1964 clashes between Greek and Turkish Cypriots. Lyssaridis was the personal physician of Archbishop Makarios III, the first president of independent Cyprus, whom the party supported. The party's name was inspired by Greek's Centre Union (EK) of Georgios Papandreou. It positioned itself in "the space inbetween" (neither left nor right). EDEK had links to the international Non-Aligned Movement and was opposed to the right-wing Colonels' regime in Greece. Many of the party's members were part of the armed resistance to the 15 July 1974 coup against Makarios. The leader of the youth section of the party, Doros Loizou, was shot and killed in an attempt to murder Lyssaridis in August 1974.
