The course examines the formation and evolution of Greek foreign policy from the establishment of the Greek state to Greece’s accession to the EEC. The starting point is the diplomatic developments related to the recognition of Greek independence. Special reference is made to the way in which the demand for territorial expansion (which took the form of the Great Idea) determined the diplomatic orientations of Greece for most of the 19th and until the beginning of the 20th century. The diplomatic components of Greece’s ten-year war expedition during the period 1912-1922 are also analyzed. The key role of the Asia Minor Disaster and the signing of the Lausanne Peace Treaty for the fundamental restructuring of Greek foreign policy, which, in its new form, began to be implemented in the interwar period, is highlighted. Greece’s participation in the Second World War as well as its membership in the Western coalition during the Cold War are also outlined. The developments surrounding the Cyprus issue and their effects on Greek-Turkish relations are presented, as well as the negative impact that the dictatorship of the colonels had on the Cyprus issue, but also on Greek foreign policy as a whole. Finally, the new diplomatic program adopted after the restoration of democracy in the summer of 1974 is presented, an organic element of which was the pursuit (and ultimately the achievement) of joining the EEC.
