The Polish People's Party (PSL) is a conservative and Christian democratic political party in Poland. The first incarnation of the party, the "Piast" faction, was founded on 1 January 1914, and the Piast faction was conservative; the socialist "Wyzwolenie" faction broke away from the party and allied itself with the Polish Socialist Party. The factions would be outlawed by Nazi Germany during World War II, operating clandestinely under Axis occupation from 1939 to 1945. In 1945, Wincenty Witos refounded the party as a conservative party, but it was dissolved in 1949 after the communist seizure of power. In 1990, its most recent incarnation was formed, and it was created as a left-wing party. It allied with the Democratic Left Alliance in 1993, and it moved to the center at the end of the 1990s, becoming a conservative party once more. It held a significant amount of regional assembly seats during the 2010s, but it remained a relatively minor party.
