Pope Sixtus V (December 13, 1521 - August 27, 1590), born Felice Peretti di Montalto, was Pope from 1585 to 1590. The subsequent administrative system of the Church owed much to Sixtus V. He limited the College of Cardinals to seventy; and doubled the number of the congregations, and enlarged their functions, assigning to them the principal role in the transaction of business (1588). He regarded the Jesuits with disfavour and suspicion. He meditated radical changes in their constitution, but death prevented the execution of his purpose. In 1589 was begun a revision of the Vulgate, the so-called Editio Sixtina.
