Clerico-Nationalism was a right-wing ideology current in Quebec from the years after World War I until the end of the 1950s, from the premiership of Maurice Duplessis until the Quiet Revolution.
Clerico-nationalist thinking was most thoroughly developed and spread by Lionel Groulx and the Ligue d'Action française (French Action League), which he led.
These more radical ideas took hold in the movements inspired by Paul Bouchard and Adrien Arcand, and the group Jeune-Canada (Young Canada).
Clerico-nationalism brought together a number of intellectuals and figures from different nationalist milieus in defense of French Canadian tradition against rising liberalism, secularism, urbanization, and capitalism in the.
[clarification needed] The often passionate debates that Clerico-nationalism stirred up focused discussion on modernity, the influence of Catholicism on political life, and the idea of progress in Quebec during a turning point in its history.
