Freedom Union (Poland) in the context of "Tadeusz Mazowiecki"

Parliamentary elections were held in Poland on 23 September 2001. All 460 members of the Sejm and 100 senators of the Senate were elected. The election concluded with an overwhelming victory for the centre-left Democratic Left Alliance – Labor Union, the electoral coalition between the Democratic Left Alliance (SLD) and the Labour Union (UP), which captured 41% of the vote in the crucial lower house Sejm. The 2001 election is recognized as marking the emergence of both Civic Platform (PO) and Law and Justice (PiS) as players in Polish politics, while also witnessing the outright collapse of the Solidarity Electoral Action (AWS) and its former coalition partner, the Freedom Union (UW).

Voter turnout for the 2001 election was 46% The 2001 election featured heavy redistricting owing to local government reforms passed in 1998. For this election only, list seats were allocated using the Sainte-Laguë method instead of the D'Hondt method.

The Civic Platform (Polish: Platforma Obywatelska, PO) was a centre-right liberal conservative political party in Poland. The party's most prominent leader was Donald Tusk, party chairman between 2003–2014 and 2021–2025.

It was formed in 2001 by splinter factions from the Solidarity Electoral Action, the Freedom Union and the Conservative People's Party, and it later placed second in the 2001 Polish parliamentary election. It remained at the opposition until the 2007 Polish parliamentary opposition, when it overtook Law and Justice, won 209 seats, and Tusk was elected as Prime Minister of Poland. Following the Smolensk air disaster in 2010, Bronisław Komorowski served as acting president of Poland and later won the 2010 Polish presidential election. Tusk continued to serve as prime minister and leader of Civic Platform until he resigned in 2014 to assume the post of the president of the European Council. The party was defeated in the 2015 Polish parliamentary and presidential elections. It placed second in the 2019 Polish parliamentary election, and its 2020 Polish presidential election candidate, Rafał Trzaskowski, won 49% of the popular vote in the second round and lost the election to Andrzej Duda.

Donald Franciszek Tusk (born 22 April 1957) is a Polish politician and historian who has served as the prime minister of Poland since 2023, previously holding the office from 2007 to 2014. Tusk was President of the European Council from 2014 to 2019 and led the European People's Party from 2019 to 2022. He co-founded the Civic Platform (PO), one of the dominant Polish political parties, and has been its longtime leader – from 2003 to 2014 and again from 2021 to 2025, when it merged into the Civic Coalition (KO) party. He is the longest-serving prime minister of the Third Polish Republic.

Tusk has been officially involved in politics since 1989, having co-founded multiple political parties, such as the free market–oriented Liberal Democratic Congress party (KLD). He first entered the Sejm in 1991 but lost his seat in 1993. In 1994, the KLD merged with the Democratic Union to form the Freedom Union. In 1997, Tusk was elected to the Senate and became its deputy marshal. In 2001, he co-founded another centre-right liberal conservative party, the PO, and was again elected to the Sejm, becoming its deputy marshal. Tusk stood unsuccessfully for President of Poland in the 2005 election and would also suffer defeat in the 2005 Polish parliamentary election.
