Defunct Historical The United People's Party (Polish: Zjednoczone Stronnictwo Ludowe, ZSL) was an agrarian socialist political party in the People's Republic of Poland.

ZSL became – as intended from its beginning – a satellite party of the Polish United Workers' Party (PZPR), representing the PZPR in the rural areas.

To keep up the appearance that Poland was ruled by a coalition, the Marshal of the Sejm (parliamentary speaker) was always a member of the ZSL.

After victory of the Solidarity trade union in the 1989 Polish legislative elections, together with the PZPR's other satellite party, the Alliance of Democrats, ZSL decided to support Solidarity.
