St. Ignatius Loyola, the founder of the Society of Jesus was born in 1491, as the last child of a large Basque family of Spain. The name of Loyola came from the ancestral castle that was the family heritage of St. Ignatius. According to the traditions of his family, Ignatius was trained to arms and to the etiquette of court life. He was badly wounded in a battle with France. As he lay convalescing at Loyola, he read the Gospel Narratives and the Lives of saints and was inspired to follow Christ by giving up all worldly ambition and trappings of power and embracing a life of poverty, sacrifice and service after the example of these saintly mentors. He began his new life at the age of 31. He spent a year of severe penance and intense prayer in a solitary cave on the banks of the river Cardoner near the town Manresa. He recorded his experiences in the book of the Spiritual Exercises, which became the soul and centre, the rule and character of every Jesuit, who came after.

Reflecting on the crisis in the Church of his time, he felt that the need of the hour was for the learned and holy priests, free of greed and ambition and ready to serve the poor and to give witness to the love of Christ for men. To achieve this objective, he set himself in earnest to study from grammar school to college and university in the various Spanish centres of learning, and finally took his Master's Degree from the Sorbonne University, Paris. At the same time, he won over a group of brilliant and like-minded university men one of whom was St. Francis Xavier (the patron saint of India), moulded them by the Spiritual Exercises and welded them into a religious fraternity which became the Society of Jesus. The followers of St. Ignatius popularly came to be known in the course of time as Jesuits.
