List of political parties in Poland

This article lists current political parties in Poland, as well as former parties dating back as far as 1918. Since 1989, Poland has had a multi-party system, with numerous competing political parties. Individual parties normally do not manage to gain power alone, and usually work with other parties to form coalition governments.

The transition from a mono-party Communist regime to liberal democracy and pluralism resulted in new political parties mushrooming in the early 1990s. After the first free parliamentary elections in 1991 seats in the Sejm were divided among more than a dozen different parties (amongst them such curiosities as the Polish Beer-Lovers' Party (Polska Partia Przyjaciół Piwa), led by a popular comedy actor, Janusz Rewiński). The existence of so many parties in the Sejm was seen by many as being counterproductive to the effectiveness of the parliament and a hindrance towards producing stable governments. Consequently, electoral reform was undertaken and an electoral threshold for the Lower House was instituted prior to the 1993 elections. The set threshold required a minimum vote of 5% for parties (with exemptions for ethnic minority parties) and 8% for electoral coalitions. The threshold was set at the national, rather than divisional, level, and had the effect of preventing many minor parties from winning seats in later elections. The threshold also prevented independent candidates from gaining election to the Sejm. Since 1990, the left side of the political scene has generally been dominated by former Communists turned social democrats. The right has largely comprised (former) Solidarity activists and supporters, but experienced deep divisions from the beginning, and showed less cohesiveness than the left. The right were unable to create a single bloc which could act as a lasting counterweight to the left-wing monolith, but instead, kept merging, splitting and renaming. Even so, the parties of the right did manage to win government again from 1997 to 2001 (having initially governed from 1989 to 1993).

Since the parliamentary elections of 2005, the right-wing parties have dominated the political scene, and appear to be in their strongest position to date. Two important developments in the political landscape have taken place since 2005. Firstly, the SLD (Communist successor) party is no longer the major, or one of the two major parties. Secondly, the main political battleground is no longer between the ex-Solidarity right versus the ex-Communist left. The new competing groupings are those of the Law and Justice party (promoting economic interventionism and social conservatism) and the Civic Platform (representing a more liberal-conservative position). The general public disapproval of politics and politicians as a whole has resulted in almost all major parties excluding the very word "party" from their names, replacing it with words less associated with politics, such as "union", "platform", "league" or "alliance".
