The family was called to Spain in 1581 to assist the Holy Roman Empress Maria of Austria. They arrived in Madrid in March 1582, where Aloysius and Rodolfo became pages for the young Infante Diego. Aloysius started thinking in earnest about joining a religious order. He had considered joining the Capuchins, but he had a Jesuit confessor in Madrid and decided instead to join that order. His mother agreed to his request, but his father was furious and prevented him from doing so.
