The deliberate process of eradicating non-French vernaculars in modern France and disparaging them as mere local and often strictly oral dialects was formalized with Henri Grégoire's Report on the necessity and means to annihilate the patois and to universalise the use of the French language,[1] which he presented on June 4, 1794 to the National Convention; thereafter, all languages other than French were officially banned in the administration and schools for the sake of linguistically uniting post-Bastille Day France. At the time, only one tenth of the population were fluent in French.[11] In reference to "patois", Jean Jaurès famously claimed that "one names patois the language of a defeated nation".[12] According to the Chambers Dictionary, the origin of the term is disputed but could be a "corruption of patrois, from LL patriensis, a local inhabitant".
