This study presents the EU's democracy promotion-policy in Sub-Saharan Africa and subjects it to a legal analysis under public international law. It begins with a historical perspective on the subject and it is shown that the external democracy promotion of the EU could only fully develop in the last 20 years. Then the EU's far-reaching definition of democracy for its external democracy promotion-policy is explained to establish the frame of reference for the further analysis of the subject. This is followed by a theoretical analysis of the EU's external democracy promotion-policy. Subsequently, the existing universal and regional standards of the right to political participation are discussed, followed by a presentation of recent developments in public international law with regard to a possibly emerging right to democratic governance. In the next chapter the tension between external democracy promotion-policies and state sovereignty is discussed. In the following part of this study the democracy promotion-instruments available to the EU are shown and subjected to an analysis under EU law. Following this, the legality of the use of these instruments under public international law is examined. Ultimately, the EU's recent external democracy promotion-policy in Côte d'Ivoire and in Nigeria is explained in detail.It is shown in this study that the EU has a number of effective instruments of external democracy promotion at hand and that their use in Sub-Saharan Africa is in most cases in line with public international law. Despite this fact, the EU is very selective in using its instruments of external democracy promotion in Sub-Saharan Africa for foreign and development policy considerations, which undermines their effectiveness. Finally, the paper concludes with an outlook on the future of the EU's external democracy promotion-policy in Sub-Saharan Africa.
