Jesuits were expelled 1618–1621 during the early stages of the Thirty Years' War, which was started in Prague by anti-Catholic and anti-Imperial Bohemians. By 1622, the Jesuits had a predominant influence over the emperor. An Imperial decree of 19 September 1622 gave the Jesuits supreme control over the entire school system of Bohemia, Moravia, and Silesia. The last four professors at the Carolinum resigned, and all of the Carolinum and nine colleges went to the Jesuits. The right of handing out degrees, of holding chancellorships, and of appointing the secular professors was also granted to the Jesuits.[citation needed]
