They were especially active in the nineteenth century in historically Catholic countries that fell under anti-clerical regimes such as Spain, Italy, Bavaria, France, and Belgium. Adolf Hitler attacked one of the heads of a Catholic Action group in Nazi Germany during the Night of the Long Knives. Catholic Action is not a political party, although in many times and places this distinction became blurred. Since World War II the concept has often been eclipsed by Christian Democrat parties that were organised to combat Communist parties and promote Catholic social justice principles in places such as Italy and West Germany.
Catholic Action generally included various subgroups for youth, women, workers, etc. In the postwar period, the various national Catholic Action organizations for workers formed the World Movement of Christian Workers which remains highly active today as a voice within the Church and in society for working class Catholics. 
A Catholic Action group was active in Australia, called "The Movement" and later the National Civic Council, under B.A. Santamaria. They were active in the Australian Labor Party, but were expelled by more left wing elements and went on to form the Democratic Labor Party.
Azione Cattolica is probably the most active Catholic Action group still around today. Catholic Action was particularly well suited to Italy where Catholic party political action was impractical, firstly under the Anti-Clerical Savoyard regime from 1870 until about 1910 and later under the Fascist regime which prohibited independent political parties.
The present association Azione Cattolica was founded in 1867 by Mario Fani and Giovanni Acquaderni with the name of Società della Gioventù Cattolica Italiana (Italian Catholic Youth Society), then reformed during the Mussolini regime when the association was structured into 4 sectors and was called Azione Cattolica.
