The Society of Jesus, whose members are known as Jesuits, is a Catholic religious order founded by Ignatius of Loyola in 1540.

Ignatius was a Spanish nobleman and soldier who dedicated his life to religion after a serious injury in battle.

The order was organized with a military-like discipline and structure, and members swore a special vow of absolute obedience to the Pope.

The Jesuits became the most effective and dynamic force of the Catholic Counter-Reformation.

Their three primary missions were education, missionary work, and combating the spread of Protestantism.

They founded hundreds of high-quality schools and universities across Europe, earning a reputation as elite educators.

Jesuit missionaries were highly disciplined and traveled the globe, spreading Catholicism to the Americas, Africa, and Asia.

They served as influential advisors and confessors to many of Europe's Catholic monarchs.

Their rigorous intellectual training made them effective debaters against Protestant theologians.

The Jesuits were instrumental in reconverting regions like Poland and parts of Germany back to Catholicism.
