This article is dedicated to the German policy towards the EU enlargement. Its history as well as the current German policy towards prospective enlargements are analyzed in this paper. The article offers party-political and sociological analysis of Germany`s attitude towards the EU enlargement, also the reasons for it are determined. FRG supported all of the European Community and European Union enlargements. This line is being continued, but nowadays only step to step approach is being supported. Germany‘s motives to the EU enlargement are based on the liberal concept of the common security. The main goals of this policy are the including of European countries into the Western community of developed countries (the EU), the extension of the stability and security area. The economic integration is also very important for Germany. The key priority of the EU enlargement is the Western Balkan region (the so called “Europeanisation” of Western Balkans). This process is being supported by political elites of the region and by the European Union itself. It is recognized, that the Europeanisation of Western Balkans was used as a sample for the Eastern Partnership Program. Without consideration of the Russian factor, though, this strategy towards the post-Soviet countries has many weaknesses. But the EU-membership for the Eastern Partnership members is not excluded.
