This article uses a representative sample of elections held in 80 countries (1992–2012) for a statistical analysis of societal and institutional factors of party system nationalization. The analysis demonstrates that high degrees of political decentralization, such as in federations and devolved states, exert a strong negative effect on party system nationalization. However, in the long-term federalism can accommodate highly nationalized party systems. Another factor that strongly contributes to party system nationalization is a high quality of democracy. The degrees to which different varieties of electoral rules support party system nationalization are associated with a lack of incentives for cultivating the personal vote. Countries with large populations and societies divided along linguistic and/or religious lines tend to have party systems that are less nationalized, but these factors are not as important as institutional determinants. The impact of some of the factors is mitigated by party system fragmentation.
