In 1852, a Union Constitutionnelle et Conservatrice was founded in Ghent, in Leuven (1854), and in Antwerp and Brussels in 1858, which were active only during elections.
On 11 July 1864 the Federation of Catholic Circles and Conservative Associations was created (French: Fédération des Cercles catholiques et des Associations conservatrices; Dutch: Verbond van Katholieke Kringen en der Conservatieve Verenigingen).
The other group which contributed to the party were the Catholic Cercles, of which the eldest had been founded in Bruges.
At the Congress of 1867, it was decided to create the League of Catholic Circles, which was founded on 22 October 1868.
At the end of World War II, on 18–19 August 1945 the party was succeeded by the PSC-CVP.
