Europeanization of the Polish party system after the 2015 and 2019 parliamentary elections

The author considers the Europeanization of the Polish party system in the electoral cycles of 2015–2019 and from 2019 to the present. Since 2015, the Polish government has been formed by one party – the right-wing conservative Law and Justice (PiS). The Polish party system is characterized as multi-party with two dominant parties. The ruling party adheres to a policy of Euroscepticism, while the leading opposition party, Civic Platform (PO), adheres to a pro-European agenda. Small parties occupy niche positions, adjoining the dominant ones. The most important documents reflecting the foreign policy orientations of parties are party programs. Content analysis of programs of parliamentary parties will determine their attitude to the European Union. In case of Poland, it can be noted that the process of Europeanization of the party system has finally taken shape, since the leading political forces – the two dominant parties (ruling and opposition) – diverge in relation to the European Union.
