Finally the Zurich council lost all patience. On March 7, 1526, it decided that anyone found rebaptizing would be put to death by drowning. Apparently their thought was, “If the heretics want water, let them have it.”
Many of the persecuted fled to Germany and Austria, but their prospects were no brighter there. In 1529 the imperial Diet of Speyer proclaimed Anabaptism a heresy, and every court in Christendom was obliged to condemn the heretics to death. During the Reformation years, between four and five thousand Anabaptists were executed by fire, water, and sword.
