Co-founded in 1950 by editor and future Prime Minister of Canada Pierre Trudeau, the publication served as an organ of opposition to the conservative government of Maurice Duplessis.
This group, combined with Cité Libre, helped foster the intellectualism that revived the Quebec Liberal Party, which defeated the Union Nationale in 1960.
Cité Libre was revived in July 1991 to help promote Canadian national unity in Quebec and combat the perceived (pro-Quebec nationalist) "political unanimism" in the province.
Cité Libre was further revived in mid-March 2008, in response to what they saw as the destruction of the progressive traditions of the Liberal Party of Canada under the leadership of Stéphane Dion.
[citation needed] For the founders, this included Dion's tacit endorsement of the Security and Prosperity Partnership North American Union (SPP-NAU) agenda.
