Final answer:
Pope Paul III gave Ignatius of Loyola the right to form the Jesuits, a significant religious order established to advance Catholicism and counter Protestantism.
Step-by-step explanation:
Pope Paul III accorded Ignatius of Loyola the right to organize a new religious group known as the Society of Jesus, or the Jesuits. Founded in the 1540s, the Jesuits became an elite religious order dedicated to spreading Catholicism, providing education to young Catholic men, converting non-Christians to Roman Catholicism, and serving as advisers to Catholic rulers in Europe. Notably, the Jesuits played a significant role in the counter-reformation efforts directed against the spread of Protestantism. Their impact was not only evident in Europe but also in overseas missions, such as in Canada, where they labored to convert native peoples and in China, where they gained converts through an accommodating approach to local practices.
