The 2001 Polish parliamentary election was held on 23 September 2001 to elect deputies to both houses of the National Assembly. 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).
