Erection of new dioceses and transfer of bishops, moreover, was not in the competence of civil authorities or of the Church in France. The result was schism between the 'Constitutional Church' and the Roman Catholic Church. The legitimate bishop of Meaux, Camille de Polignac, refused to take the oath, and therefore the episcopal seat was declared vacant. Two-thirds of the clergy of Meaux, however, took the oath. On 27 February 1791 the electors of Seine-et-Marne were assembled, and on 18 March, after three ballots, they elected the parish priest of Dontilly, Pierre Thuin. Thuin travelled to Paris for his consecration, which was carried out on 27 March by Jean-Baptiste Gobel, the titular Bishop of Lydda, who had just been installed as Constitutional Bishop of Paris. Thuin's installation at Meaux was not attended by the Canons of the Cathedral or by the directors of the diocesan seminary. Bishop de Polignac emigrated to Switzerland and then to Hungary; he did not return until 1814. Thuin, and all the Constitutional Bishops, were required to resign in May 1801 by First Consul Bonaparte, who was negotiating a treaty with Pope Pius VII, the Concordat of 1801 (15 July 1801). Once the Concordat went into effect, Pius VII was able to issue the appropriate bulls to restore many of the dioceses and to regulate their boundaries, most of which corresponded closely to the new 'départements'. The Concordat of 1801 gave to the Diocese of Meaux the department of Marne, but in 1821 and 1822 the territory of the department of Marne was separated from Meaux and distributed to the Diocese of Reims and the Diocese of Châlons.
