The two-party tendency in Poland’s political system: manifestations, causes and prospects

Abstract

The article analyses the Polish political system and the increasing role of two political parties in it. This tendency has been observed in Poland for more than 15 years. We can draw a conclusion that two-and-a-half-party system has formed in Poland. Using Duverger’s phrasing, there is a “two-party tendency” in the functioning of the Polish model. The study analyses the facts that firm up this conclusion: not only the distribution of seats in the Sejm (the main criterion) but also many other quantitative and qualitative characteristics of the political system contribute to the development of the current political trend. The main goal of this article is to identify the factors that have led to the emergence and development of the tendency and assess the prospects of its further evolution, considering that both leading parties face multiple difficulties. The article concludes by pointing out that Poland is unlikely to continue strengthening its two-party tendency, and could instead return to the multiparty system with many influential parties which is more characteristic of the country historically. However, in recent years the leading role of two parties in the political system has had more positive effects rather than negative ones.
