Bronisław Komorowski in the context of "Law and Justice"

Tadeusz Mazowiecki (IPA: [taˈdɛ.uʂ mazɔˈvjɛt͡skʲi] ; 18 April 1927 – 28 October 2013) was a Polish author, journalist, philanthropist and politician, formerly one of the leaders of the Solidarity movement, and the first non-communist Polish prime minister since 1946, having held the post from 1989 to 1991.

He was the founder and leader of Democratic Union and Freedom Union. Between 1991–2001, he was a member of the Polish Parliament. In the years 2010–2013, he served as advisor to President Bronisław Komorowski. He is the recipient of Poland's highest order of merit, the Order of the White Eagle.

The Siedlce University (Polish: Uniwersytet w Siedlcach) is a higher-education institution in Siedlce, Poland. It was created on October 1, 2010, by the decision of Sejm signed by the President of the Republic of Poland, Bronisław Komorowski. The previous name of the university was 'Akademia Podlaska w Siedlcach', in English known officially as University of Podlasie.

Presidential elections were held in Poland on 10 and 24 May 2015. In the first round of voting Law and Justice (PiS) candidate, lawyer and Member of the European Parliament, Andrzej Duda received the highest number of votes with a share of 34.76%, followed by the incumbent president Bronisław Komorowski (with 33.77%), who ran as an independent with the endorsement of the Civic Platform (PO), whose membership he had renounced after winning the 2010 elections. Independent candidate Paweł Kukiz came in third with 20.80% of the votes. As no candidate had received more than 50% of the votes cast, a second round was held on 24 May between the two highest-placed candidates, Duda and Komorowski. This round was won by Duda with 51.5% of the votes, to Komorowski's 48.5%.

Andrzej Sebastian Duda (born 16 May 1972) is a Polish lawyer and politician who served as the 6th president of Poland from 2015 to 2025. Before becoming president, he served as Member of the Sejm (MP) from 2011 to 2014 and as Member of the European Parliament (MEP) from 2014 to 2015.

Born in Kraków, Duda ran in the 2015 presidential election as candidate for the Law and Justice (PiS) party and defeated the incumbent president Bronisław Komorowski in a surprising and significant upset. In the first round of voting, he narrowly placed first but fell well short of the required absolute majority, finally winning in the second round of voting, receiving 51.55% of the vote. On 26 May 2015, Duda resigned his party membership as the president-elect.

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.

Presidential elections were held in Poland on 20 June 2010. As no candidate received a majority of votes in the first round, a second round was held on 4 July 2010. Bronisław Komorowski, the acting President of Poland and vice-chairman of the Civic Platform, defeated Jarosław Kaczyński, twin brother of the recently deceased President Lech Kaczyński and chairman of Law and Justice (PiS). The 2008 financial crisis, flooding in Poland and the Smolensk disaster were the main themes in the last months of the election campaign.

As of 2025, this remains the last Polish presidential election won by a non PiS-aligned candidate and the only election won by a candidate from PO.
