Constitutional bishop Under the new
Civil Constitution of the Clergy, to which he was the first priest to take the oath (27 December 1790), Grégoire was elected bishop by two
départements. He selected that of
Loir-et-Cher, but assumed the old title of
bishop of Blois, and for ten years (1791–1801) governed his diocese with exemplary zeal. An ardent
republican, he strongly supported
Collot d'Herbois' motion for the
abolition of the monarchy in the first session of the
National Convention (21 September 1792) with the memorable phrase "Kings are in morality what monsters are in the world of nature." On 15 November 1792, he delivered a speech in which he demanded that King
Louis XVI be brought to trial, and immediately afterwards was elected president of the Convention, over which he presided in his episcopal street dress. During the trial, being absent with other three colleagues on a mission for the union of
Savoy to France, he along with them wrote a letter urging the condemnation of the king, but attempted to save the life of the monarch by proposing that the death penalty should be suspended. When, on 7 November 1793,
Jean-Baptiste-Joseph Gobel,
bishop of Paris, was intimidated into resigning his episcopal office at the bar of the Convention, Grégoire, who was temporarily absent, hearing what had happened, faced the indignation of many deputies, refusing to give up either his religion or his office. This display of courage ultimately saved him from the
guillotine. Throughout the
Reign of Terror, in spite of attacks in the Convention, in the press, and on placards posted at the street corners, Grégoire appeared in the streets in his episcopal dress and celebrated daily
Mass in his house. He was then the first to advocate the reopening of the churches (speech of 21 December 1794). Grégoire also coined the term
vandalism in reference to the destruction of property that occurred during the Revolution, both that which was ordered by the
National Convention and that which occurred at the hands of individuals. In a series of three reports issued to the
National Convention in 1794, Grégoire advocated for additional protection of art works, architecture, inscriptions, books, and manuscripts. He is credited by scholars, such as
Joseph Sax and Stanley Idzerda, as one of the founders of the idea of
preservation of cultural objects.
Annihilating the dialects of France The Abbé Grégoire is also known for advocating a unified French national language, and for writing the ''Rapport sur la Nécessité et les Moyens d'anéantir les Patois et d'universaliser l'Usage de la Langue française'' (Report on the necessity and means to annihilate the patois and to universalise the use of the French language), which he presented on 4 June 1794 to the
National Convention. According to his own research, the vast majority of people in France spoke one of 33 dialects or
patois, and he argued that French had to be imposed on the population and all other dialects eradicated. Although he was natively raised with knowledge of the
Lorrain "patois", his conclusion came from a common view at the time within Jacobin circles that the linguistic diversity of France had been purposely used by the nobility of France to keep the various linguistic groups of France separated from one another and from the political institutions in which French was primarily spoken. That made Grégoire see the various patois as limiting to the ability of French citizens to practice their individual rights. However, his work was still influenced by the rising sense of French linguistic superiority that had been started by
Bertrand Barère with
Rapport du Comité de salut public sur les idiomes (1794)
. He thus classified
Corsican and
Alsatian as "highly degenerate" (
très-dégénérés) forms of Italian and German, respectively. In his view,
Occitan was decomposed into a variety of syntactically-loose local remnants of the language of
troubadours that were mutually unintelligible and should be abandoned in favor of the language of Paris. Thus began a process that was expanded dramatically by
the policies of
Jules Ferry a century later and led to the declining use of the regional languages in France. ==Advocate of equality==
