ABSTRACTCroatia is regarded as a success story of the EU’s enlargement policy. However, this narrative conflicts with the situation on the ground and with expert surveys, which depict incremental, yet persistent democratic backsliding in recent years. A shift towards illiberal practices, primarily focused on the liberal part of the liberal-democratic nexus, is taking place. This research aims to explore the prevalence and causes for the re-emergence of illiberal practices in Croatia by employing an interpretive method to evidence gathered from media articles and research reports published 2013–2019. The use of illiberal policies by the governing Croatian Democratic Union (HDZ) in three areas of the political system – the capture of independent agencies, control of the judiciary, and the weakening of independent media – is found to be the driver of democratic backsliding. Causes are found in structural reasons linked to the dominant party. Without either internal power-sharing constraints or external EU conditionality pressure, the HDZ has been able to take advantage of structural weaknesses of the system it built and shaped during the 1990s.
