Bronisław Maria Komorowski (Polish: [brɔˈɲiswaf kɔmɔˈrɔfskʲi] ⓘ; born 4 June 1952) is a Polish politician and historian who was the fifth president of Poland from 2010 to 2015. Komorowski previously served as Minister of National Defence from 2000 to 2001. As Marshal of the Sejm, Komorowski exercised the powers and duties of acting president following the death of President Lech Kaczyński in a plane crash on 10 April 2010. Komorowski was then the governing Civic Platform party's candidate in the resulting presidential election, which he won in the second round of voting on 4 July 2010. He was sworn in as president on 6 August 2010. Komorowski thus became the second person to serve on two occasions as Polish head of state since 1918, after Maciej Rataj. On 24 May 2015, Komorowski was defeated in the second round by Andrzej Duda in the 2015 presidential election. As a result, Komorowski was succeeded by Duda on 6 August 2015. Komorowski was the only president of the Third Polish Republic not to experience a cohabitation while in office. As of 2025, he remains the only Polish president elected with the backing of the Civic Platform party.
