A nation's foreign policy is often subject to change. This change may occur in its relations with other nationstates or with international organizations such as the European Economic Community (E.E.C.). Greece became a full E.E.C. member in January, 1980, when the conservative Nea Democratia was in power. The Nea Democratia, both in government from 1974 to 1981 and in opposition since 1981, has been consistent in its support for the E.E.C.; in contrast, the Panhellenic Socialist Movement (PASOK) has not. PASOK, in opposition from 1974 to 1 981 , was against Greek membership in the European communities. PASOK, in its first term in office from 1981 to 1985, reversed itself on the issue. During this period, PASOK made no effort to withdraw Greece from the E.E.C. This study examines PASOK's reversal of policy. Two domestic factors are examined in detail: the general economic difficulties of Greece during PASOK's first term, and the role of the powerful agrarian interests.
