Founding of the Society of Jesus
Ignatius of Loyola and six companions founded the Jesuits, creating a religious order that would transform Catholic education, missions, and intellectual life.
In 1534, a former Spanish soldier named Ignatius of Loyola and six friends, including Francis Xavier, took vows in a chapel on Montmartre in Paris. Six years later, Pope Paul III formally approved their new order, the Society of Jesus. The Jesuits were different from anything the Church had seen. They did not wear distinctive habits, did not chant the Divine Office in common, and placed themselves directly under the Pope's authority. Their training was rigorous and unusually long, often fifteen years, producing priests who were scholars, scientists, diplomats, and missionaries. Within a generation, Jesuits were everywhere: running schools across Europe, establishing missions from Japan to Paraguay, advising kings, and mapping continents. Francis Xavier reached India, Southeast Asia, and Japan. Matteo Ricci earned the respect of the Chinese imperial court. In South America, Jesuits created the famous Reductions, self-governing indigenous communities that protected native peoples from colonial exploitation. The order also made enemies. Their influence at Catholic courts, their involvement in politics, and suspicion of their methods led to their suppression by Pope Clement XIV in 1773. They were restored in 1814 and today have produced the first Jesuit pope, Francis.
Why it matters
Created the most influential religious order of the modern era, reshaping Catholic education, global missions, and the Church's intellectual tradition.
What Happened
Ignatius of Loyola, a Basque soldier whose leg was shattered by a cannonball, underwent a deep conversion during his recovery. He developed the Spiritual Exercises, a structured program of prayer and discernment, and gathered companions at the University of Paris. They took vows in 1534 and received papal approval in 1540. The order grew rapidly, founding colleges, sending missionaries to every continent, and becoming the intellectual vanguard of the Catholic Counter-Reformation.
Why It Still Matters
The Jesuits operate the largest network of Catholic schools and universities in the world. Their approach to education, integrating faith and reason, shaped generations of Catholic thinkers. The Spiritual Exercises remain one of the most widely used tools for prayer and decision-making in the Church. With Pope Francis, a Jesuit sits on the Chair of Peter for the first time, bringing Ignatian spirituality, with its emphasis on discernment, finding God in all things, and service to the poor, to the center of Catholic life.
