What happened

Ignatius of Loyola, a Basque soldier severely wounded at the 1521 Battle of Pamplona, spent his convalescence reading devotional literature and emerged convinced he was called to religious service. After studying theology at the University of Paris, he gathered six companions who committed themselves to a vision of a mobile order of priests ready to spread Catholic teaching and defend the faith wherever needed, including missions as distant as Jerusalem if circumstances allowed. Pope Paul III formally approved the resulting Society of Jesus in 1540, and Ignatius became its first Superior General.

Why it matters

The Jesuits became one of the Counter-Reformation's most effective tools, producing highly educated, multilingual priests who established schools and missions across Europe, the Americas, and Asia, including Japan, at a scale no earlier religious order matched. Their emphasis on rigorous education and direct engagement with Protestant strongholds helped the Catholic Church reclaim intellectual ground it had ceded to reformers.

How we know

The Society's founding constitution and Ignatius's own Spiritual Exercises survive as primary documents, and papal approval is recorded in the Church's own archives; the World History Encyclopedia's biography of Ignatius documents his path from soldier to founder and the 1540 papal approval.
