Socially conservative but economically to the left, the Christian National Union (Zjednoczenie Chrzescijansko-Narodowe-- ZChN) was the dominant member of a short-lived electoral alliance known as Catholic Action. The alliance finished third in the 1991 parliamentary elections and earned ZChN forty-nine Sejm and nine Senate seats. The ZChN supported the involvement of the Roman Catholic Church in politics and government, religious instruction in the schools, a generous social welfare program, and trade protectionism. The party played a large role in both the Olszewski and Suchocka governments. Under Suchocka, the ZChN held five cabinet positions and the post of deputy prime minister for economic affairs.
