Following the Estates General of French Canada, whose preparation began in 1964 and occurred between 1967 and 1969, the MNQ took a stance in favour of an independent Quebec and gave itself the mission to promote: It was founded by nine SSJB branches.
It has 19 affiliated societies:[2] In 1947, nine of Quebec's SSJB (those of Sherbrooke, Trois-Rivières, Quebec City, Rimouski, Saint-Hyacinthe, Nicolet, Hull, Saint-Jean and Chicoutimi), formed the Fédération des Sociétés Saint-Jean-Baptiste du Québec during a congress in Sherbrooke.
The federation participated to the popular movement that led to the adoption of the fleurdelisé as Quebec's Flag in 1948, organized the National Conference on Education which led, in 1964, to the creation of a Quebec Ministry of Education, and helped with setting in motion the Estates General of French Canada.
Strongly committed against institutional bilingualism and for territorial unilingualism, the MNQ was active in the political movement that opposed the Act to promote the French language in Quebec (1969) and the Official Language Act (1974) and supported the Parti Québécois's (PQ) proposed interventionist policy.
[5] It also supports PQ National Assembly member Daniel Turp's initiative to obtain a .qc country code for Quebec following the precedent of a .cat for Catalonia.
