The year 1968 was a milestone in the history of the Communist Party of Greece (KKE), which was celebrating the 50th anniversary of its establishment. This paper will analyse the peculiarities of the division of 1968 and its impact on the Greek left, especially on the life of Greek refugees in Czechoslovakia. The paper is based primarily on materials available in the National Archives of Prague and also in the archives of the refugee newspaper Agonistis. The article highlights in chronological order the reactions of the KKE and the Czechoslovak leadership to the news of the military coup in Greece, focusing chiefly on those reactions caused by the split of the KKE in conjunction with the changes brought about by the Prague Spring and its violent repression.
