the struggle against the Reformation. The change greatly restricted the limits of the Diocese of Cambrai, which, when thus dismembered, was made by way of compensation an archiepiscopal see with the dioceses of Saint Omer, Tournai and Namur as suffragans. The councils of Leptines, at which Saint Boniface played an important role, were held in what was then the part of the former Diocese of Cambrai in the Southern Netherlands. Under King Louis XIV the Bishopric of Cambrai finally became French after the Siege of Cambrai of 1677, confirmed in the Treaties of Nijmegen of 1678 and 1679. From 1790 Cambrai was part of the new Nord department. By the Napoleonic Concordat of 1801, Cambrai was again reduced to a simple bishopric, suffragan to Paris, and included remnants of the former dioceses of Tournai, Ypres, and Saint Omer. In 1817 both the pope and the king were eager for the erection of a see at Lille, but Bishop Louis de Belmas (1757–1841), a former constitutional bishop, vigorously opposed it. Immediately upon his death, in 1841, Cambrai once more became an archbishopric, with the diocese of Arras as suffragan. List of bishops and archbishops Notable people The list of notable people associated with the Diocese of Cambrai is very extensive, and their biographies, although short, take up no less than four volumes of the work by Canon Destombes. Exclusive of those saints whose history would be of interest only in connection with the Belgian territory formerly belonging to the diocese, mention may be made of: Blessed Evermod, disciple of Saint Norbert and first Bishop of Ratzeburg in Germany (twelfth century); Blessed Charles le Bon, Count of Flanders, son of King Canute IV of Denmark and assassinated at Bruges in 1127; Blessed Beatrice of Lens, a recluse (thirteenth century). The Jesuits Cortyl and du Béron, first apostles of the Pelew Islands, were martyred in 1701, and Chomé (1696–1767), who was prominent in the Missions of Paraguay and Argentina in the province of Misiones, also the Oratorian Gratry (1805–1872), philosopher and member of the French Academy, were natives of the Diocese of Cambrai. The English college of Douai, founded by William Allen in 1568, gave in subsequent centuries a certain number of apostles and martyrs to Catholic England. Since the promulgation of the law of 1875 on higher education, Lille has been the seat of important Catholic faculties. Notable French and Flemish composers
