In the postcommunist period, political parties in Central and Eastern Europe (CEE) had to convincingly demonstrate that they are a vital part of a functioning democratic society. Well-developed intraparty democracy (IPD) is one way of accomplishing this. By asking what factors are relevant to an explanation of IPD formation, we present an analytical framework in which the formation of IPD can be investigated and explore the patterns of IPD and their determinants. We draw on a newly constructed data set based on standardized content analysis, including 129 party statutes from 14 major political parties from Hungary, Romania, and Slovakia between 1989 and 2011. Relying on unit fixed-effects regression approaches, our analyses suggest that especially imperatives related to party origin and Europeanization have important implications for the formation of IPD within CEE parties.
