Appletons' Cyclopaedia of American Biography stated that Plessis "studied classics in the
College de Montreal, but refused to continue his education, and his father, who was a
blacksmith, set him to work at the
forge. After a short experience at manual labour, he consented to enter the Petit Seminaire of Quebec in 1780. On finishing his course he taught
belles-lettres and
rhetoric in the College of Montreal, and notwithstanding his youth became secretary to Bishop
Briand. He was
ordained priest on 29 Nov., 1786". Shortly after his ordination he was made secretary to Bishop
Jean-Francois Hubert, and he exercised so much influence over this prelate that he really filled the functions of auxiliary bishop. In 1792 he was appointed Curé of Notre-Dame at Quebec. Bishop
Pierre Denaut, Hubert's successor, named Plessis his grand
vicar in 1797, and at the same time announced his intention of appointing him
coadjutor bishop. The popularity of Plessis with French Canadians excited the hostility of the English party, and General Prescott, the governor of the province, opposed the appointment, but he finally yielded to the demands of public opinion. Plessis was consecrated bishop in the Cathedral of Quebec on 21 January 1801, in the presence of the governor and officials of the province. The death of Bishop
Denaut raised him to the episcopal sea of Quebec in 1806. He began his administration under difficult circumstances. Efforts were made to appropriate the property of the
Jesuits and of the Seminary of Montreal to the uses of the state, to organize an exclusively
Protestant system of public instruction, and to give a power of veto on the nomination of priests and the erection of
parishes to the English crown. An unsuccessful attempt was made to prevent him from taking the oath of allegiance in his capacity as bishop of Quebec. In 1810 Gov. Craig sent a messenger to England to complain of the bishop's conduct, but the authorities adopted a conciliatory policy, Craig was recalled, and Sir
George Prevost was sent to replace him. The new governor had several interviews with the bishop, who refused to make any concessions, and finally all his demands in behalf of the
Roman Catholic Church in Canada were conceded. The part that he took during the
War of 1812 in exciting the loyalty and warlike spirit of the French Canadians gained him the goodwill of England. He received letters from the government recognizing his title and jurisdiction as
Roman Catholic bishop of Quebec, and granting him a pension of a thousand louis a year with a seat in the
Legislative Council of Lower Canada. == Legacy ==
