The Radical Peasant Party (Polish: Chłopskie Stronnictwo Radykalne, ChSR) was a political party in Poland.
The party was established in 1919, with the radical priest Eugeniusz Okoń and Tomasz Dąbal amongst its founders.[4] It received around 1% of the vote in the 1922 elections, winning four seats in the Sejm.[5] However, two MPs left to join the new Peasant Party in 1926.
The 1928 elections saw the CSR's vote share fall to 0.4%, and it lost all its seats in the Sejm.[5] It ceased to exist the following year.[6]
