It had its roots in the Christian Democratic Political Theory Club, which had been established the year before by members of the Association for the Promulgation of Catholic Social Science.

[5] It was initially known as the Christian Democratic Labour Party (Chrześcijańsko-Demokratyczne Stronnictwo Pracy, ChDSP), and claimed to be the successor to the Labor Faction that was dissolved after World War II.

It was reactivated on the initiative of former activists from the pre-war party, associated with the Christian-Democratic Political Thought Club (Polish: Chrześcijańsko-Demokratyczny Klub Myśli Politycznej) established in 1988.

[2] Although structures had to be built practically from scratch after 1989, the ChDSP boasted a long tradition, a steadily growing membership, and experienced activists such as Władyslaw Siła-Nowicki.

It split over whether to support Siła-Nowicki or Solidarity leader Lech Wałęsa in the 1990 presidential elections, with the Wałęsa-supporting faction breaking away to form the Christian Democratic Party "Union".

[7] The remaining members of the ChDSP subsequently contested the 1991 parliamentary elections as part of the Christian Democracy alliance that won five seats.

It was part of the Solidarity Electoral Action alliance that won the 1997 elections; the ChD-SP held one of its 201 seats in the Sejm,[6] taken by Witold Nieduszyński.

Prior to the 2005 elections the party split, with some members leaving to form the All-Poland Civic Coalition and others founded Ancestral Home.

Economically, the party believed that the country should relinquish its communist-era monopolies, and state ownership of the means of production or central planning should be forbidden, with all state-owned properties either privatized or liquidated.
