Before Anabaptism proper was introduced to South Tyrol, Protestant ideas had been propagated in the region by men such as Hans Vischer, a former Dominican. Some of those who participated in conventicles where Protestant ideas were presented later became Anabaptists. As well, the population in general seemed to have a favorable attitude towards reform, be it Protestant or Anabaptist. George Blaurock appears to have preached itinerantly in the Puster Valley region in 1527, which most likely was the first introduction of Anabaptist ideas in the area. Another visit through the area in 1529 reinforced these ideas, but he was captured and burned at the stake in Klausen on September 6, 1529.
