The Czech defeat at the Battle of White Mountain was followed by measures that effectively secured Habsburg authority and the dominance of the Roman Catholic Church. Many Czech nobles were executed; most others were forced to flee the kingdom. An estimated five-sixths of the Czech nobility went into exile soon after the Battle of White Mountain, and their properties were confiscated. Large numbers of Czech and German Protestant burghers emigrated. In 1622, Charles University was merged with the Jesuit Academy, and the entire education system of the Bohemian Kingdom was placed under Jesuit control. In 1624 all non-Catholic priests were expelled by royal decree.
