Archbishop Paris of Lodron led Salzburg to peace and prosperity during the Thirty Years' War in which the rest of Germany was thoroughly devastated. During the reign of Leopold Anthony of Firmian, Protestants emerged more vigorously than before. He invited the Jesuits to Salzburg and asked for help from the emperor, and finally ordered the Protestants to recant or emigrate - about 30,000 people left and settled in Württemberg, Hanover and East Prussia, and a few settled in Georgia in the United States of America. The last Prince-Archbishop, Hieronymus of Colloredo, is probably the most well known for his patronage of Mozart. His reforms of the church and education alienated himself from the people.
