Law and Justice (Polish: Prawo i Sprawiedliwość [ˈpravɔ i ˌspravjɛˈdlivɔɕt͡ɕ] , PiS) is a right-wing populist and national-conservative political party in Poland. The party is a member of European Conservatives and Reformists Group. Its chairman has been Jarosław Kaczyński since 18 January 2003.
It was founded in 2001 by Jarosław and Lech Kaczyński as a direct successor of the Centre Agreement after it split from the Solidarity Electoral Action (AWS). Despite a poor showing in the 2001 parliamentary election, where it came 4th, it would later win the 2005 presidential and parliamentary elections. Following this victory, PiS formed the Marcinkiewicz and Kaczyński governments. For a brief period, the governments included coalition ministers from the League of Polish Families and Self-Defence before collapsing in 2007. In the 2007 snap election, the rival Civic Platform (PO) emerged victorious and formed a coalition with the Polish People's Party. The coalition served two terms, retaining a majority in the 2011 parliamentary election. Law and Justice also lost the presidency following the death of president Lech Kaczński and many government officials in the Smolensk air disaster — acting president Bronisław Komorowski of PO would be officially elected to the presidency in 2010, winning against Jarosław Kaczyński in the second round. Law and Justice concluded its period in the opposition in 2015, where it won an upset victory in the 2015 presidential election and an outright majority of seats in the 2015 parliamentary election, retaining its majority in 2019 and the presidency in 2020. It governed the country for 8 years, forming the Szydło and Morawiecki cabinets, until losing its parliamentary majority in 2023 and returning to an opposition despite winning the largest amount of seats. The party's candidate, Karol Nawrocki, scored another upset victory in the 2025 presidential election.
