Since the 2015 elections, Poland has ‘enjoyed’ the attention of social sciences—political science in particular—to an extent greater than at any time since the period of “Solidarity” in the early 1980s. In contrast to that period, Poland’s idiosyncratic development over the last two and a half years can hardly be said to play the function of a normative role model. Political developments in Poland in recent times devolve into two stories: one of profound civilizational, economic and social development prior to the 2015 elections; the other of an unexpected and sudden shift toward the dismantling of the liberal democratic system after the Law and Justice (PiS) party came to power in late 2015. The first part of this article describes the most important features of pre-2015 political developments in Poland and identifies key determinants of vote choice in the 2015 parliamentary election in Poland. In brief, this analysis shows two things: that there was no ‘demand’ for systemic change at these elections, and that support for the winning party was mainly determined by socio-cultural factors rather than economic ones. The second part of the article aims to answer the question of why the PiS government has embarked on a course of political action that violates both the abstract principles of liberal democracy and concrete, binding provisions of Poland’s 1997 Constitution. Several theoretical and speculative ideas are offered in answer to this question.
