Gregory XV, Alessandro Ludovisio (January 9, 1554 - July 8, 1623), pope (1621-1623), born at Bologna in 1554, succeeded Paul V on February 9, 1621. Beyond assisting the German emperor against the Protestants, and the king of Poland against the Turks, he interfered little in European politics. He was a learned divine and manifested a reforming spirit; and his pontificate was marked by the canonization of St Theresa of Avila, Francis Xavier, Ignatius Loyola, and Philip Neri. He died on July 8, 1623, and was succeeded by Urban VIII.
