POPE GREGORY XIII
(Ugo Buoncompagni)
The Jesuits had been among the first Christian missionaries to Japan. Educationally very strong they developed Latin-Japanese dictionaries and taught other Jesuits Japanese and soon, the Jesuits were not only successful at converting Japanese to Christianity, but they were fantastic as merchants and traders. They made so much money that the Jesuit order became a power itself to some rivaling the Vatican. The Jesuits had an independence from the Catholic Hierarchy and their money allowed them to get almost anything they wanted. This famous Bull, in effect, gave the Jesuits a monopoly on trade and on souls.
Pope Gregory XIII (7 January 1502 – 10 April 1585), born Ugo Boncompagni, was head of the Catholic Church and ruler of the Papal States from 13 May 1572 to his death in April 1585. He is best known for commissioning and being the namesake for the Gregorian calendar, which remains the internationally accepted civil calendar to this day.
