Maigrot, Charles a French Jesuit and missionary, was born at Paris in 1652; entered the order and prepared for missionary labors in foreign parts. In 1681 he was sent to Siam, and in 1683 he was placed in charge of the missions of China.
In 1698 pope Innocent XII created him, for his zeal in propagating Christianity among the inhabitants of the "Middle Kingdom," bishop in partibus of Conon. In 1699 he was visited with the displeasure of his order for his opposition to the peculiar manner in which the Jesuits sought to advance the interests of Christianity among the Chinese. He was even at one time in danger of his life. Supported by the Dominicans, he appealed to pope Clement XI, who, June 20, 1702, gave his approval to the attitude of the bishop of Conon; and, to make known his will, dispatched cardinal De Tournon to the emperor of China, who. as we have seen in the article on China, was greatly displeased with the conduct of the Christian missionaries, and issued an edict ordering them all from his domains. Maigrot at first refused to obey the imperial command, and only quitted the country when his life was imperilled. He went to Rome by way of Ireland, and died in the Eternal City Feb. 18, 1730. He only wrote one work, and that is still in MS. form; it is entitled De Sinica Religione (4 vols. fol.).
