Pope Gregory XV (Latin: Gregorius XV; Italian: Gregorio XV; 9 January 1554 – 8 July 1623), born Alessandro Ludovisi, was the head of the Catholic Church and ruler of the Papal States from 9 February 1621 until his death in 1623. He is notable for founding the Congregation for the Propagation of the Faith, an organization tasked with overseeing the spread of Catholicism and missionary work. Gregory XV was also responsible for the canonization of Saints Ignatius of Loyola, Francis Xavier, Teresa of Ávila, and Philip Neri, which solidified his commitment to the Counter-Reformation.
