Grande Noirceur
The Grande Noirceur (French pronunciation: [ɡʀɑ̃d nwaʀsœ:ʀ], English, Great Darkness) refers to the regime of conservative policies undertaken by the governing body of Quebec Premier Maurice Le Noblet Duplessis from 1936 to 1939 and from 1944 to 1959.
In today's historiography of Quebec (at least since the 1990s), most scholars express the opinion that the notion of Grande Noirceur was a myth invented by those who embraced or spearheaded the Quiet Revolution in the 1960s.
