Although consisting of EU (potential) candidate countries, the Western Balkan Six (WB6: Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia) remain largely absent from the study of party politics. Mapping the dominant lines of party contestation in the region and comparing them cross-nationally is vital to understanding what types of ideological conflicts divide the parties of this region, how programmatic the party systems are, and whether they resemble other party systems. We are the first to use and validate the 2019 Chapel Hill Expert Survey to investigate which issues structure Western Balkan party systems and to quantitatively map these systems. Generally, these party systems are weakly programmatic, unidimensional, and structured along cultural issues with a background consensus on the EU. This article contributes to the scholarly understanding of party competition in a geopolitically important region and facilitates future research on party systems in young democracies.
