The aim of this study is to analyse Polish-German relations during the periods of the rule of the Law and Justice party (from 2005 to 2007 and from 2015 until now), and to indicate the key elements of continuity and changes in Poland’s foreign policy towards its western neighbour. The main thesis is the conclusion that the Federal Republic of Germany is an example of the dominant state in the political thought of the Law and Justice party. It is part of the concept of the so-called external enemy against which a determined and consistent foreign policy must be pursued.
