A Catholic religious order for men founded by Ignatius of Loyola (1491-1556) in 1534 and approved by Pope Paul III in 1540. The constitution for the community, written by Ignatius and approved in 1550, focused on two tasks: the reform of the Roman Catholic Church, particularly in response to Protestantism, and service in the foreign missions, especially in those areas that had been just discovered. To fulfill these tasks, in addition to the vows of poverty, chastity, and obedience (to one's superior in the order) Jesuits were required to take an additional "fourth vow" of obedience to the pope and were freed of traditional obligations associated with religious life, particularly a distinctive garment and the recitation of the Divine Office, daily prayers at specified hours. The Jesuits were most associated with spiritual revival, especially through the Spiritual Exercises (1522-41) of Ignatius, and education. Many of the important theologians of the sixteenth- and seventeenth-century Catholic Reformation period were Jesuits. Although marred by several conflicts during the seventeenth and eighteenth centuries, including their dispute with Jansenism, the Chinese rites controversy, and the suppression of the Society by Clement XIV in 1773 (although later restored by Pius VII in 1814), the Jesuits remain one of the most important orders in the contemporary Church, particularly in the field of education.
