Practitioners and academics clearly established that participation in the EU system of foreign policy-making transforms national foreign policies. Whilst there have been detailed studies of the impact of participation in EU foreign policy on the original fifteen member states there are, as yet, few academic studies that have thoroughly investigated the impact of progressive integration in the area of EU foreign and security policy on the new (i.e. those who joined since 2004) member states. This thesis aims to address this deficit by focusing on the impact of Poland's participation in the Common Foreign and
Security Policy (CFSP). It examines the processes of 'downloading', as it is argued here
that involvement in CFSP has had a direct effect on both the procedures of foreign policy-making in the Polish Ministry of Foreign Affairs (MFA) and, on the substance of Polish foreign policy as well as the impact of 'uploading' from member states to the EU level and 'crossloading' between EU member states. The thesis addresses the relevant conceptual issues and provides an outline of the academic debate regarding Europeanisation and foreign policy. It identifies three mechanisms that are responsible for change: conditionality, socialisation and learning. It
suggests that a member state first adapts its national foreign policy to bring it in line with
the EU's acquis politique and introduces basic changes in its institutional procedures in
order to effectively participate in the EU's CFSP. Only later, does socialisation and
learning result in changes to how national foreign policy is made, which then facilitates
both changes to the substance of national policy and the uploading of national preferences to the EU level. A two-phase model of change is introduced which identifies April 2003, when Poland first became an active observer within the EU, as the date when Europeanisation began.
The thesis provides a brief explanation of the transformation of Polish foreign policy after 1989, in order to provide contextual background for the four substantive chapters which follow: one procedural on the changes in the Polish MFA and three related to policy substance. The latter three chapters examine the Europeanisation of policy towards Poland's East European neighbours in general and policies towards Ukraine and Belarus in particular. The thesis concludes with a set of methodological and conceptual
observations followed by analysis of the empirical findings.
