Jesuits. The Society of Jesus, founded by St. Ignatius Loyola and approved by Pope Paul III in 1540. As conceived by the founder, it had a twofold aim: to strengthen and where necessary to restore the Catholic faith in the wake of the Protestant Reformation, and to preach the Gospel in non-Christian lands.

New France (French: Nouvelle-France) was the area colonized by France in North America during a period extending from the exploration of the Saint Lawrence River, by Jacques Cartier in 1534, to the cession of New France to Spain and Britain in 1763.

Four Jesuit priests came to Quebec in 1625. Although it was intended that others should follow at once, their number was not substantially increased until seven years later, when the troubles with England were brought to an end and the colony was once more securely in the hands of the French. Then the Jesuits came steadily, a few arriving with almost every ship, and either singly or together they were sent off to the Indian settlements.

More missionaries kept coming, however; the work steadily broadened; and the posts of service were multiplied. In due time the footprints of the Jesuits were everywhere, from the St. Lawrence to the Mississippi, from the tributaries of the Hudson to the regions north of the Ottawa. Priests such as: Le Jeune, Masse, Brebeuf, Lalemant, Ragueneau, Le Dablon, Jogues, Gamier, Raymbault, Peron, Moyne, Allouez, Druilletes, Chaumonot, Menard, Bressani, Daniel, Chabanel, and a hundred others were active around 1625.

The outposts in the Indian country were the chief scene of Jesuit labors from 1615 to about 1700, when the emphasis shifted to the St. Lawrence valley.
