Starting in 1522, followers of Martin Luther and Huldrych Zwingli began to preach the Protestant Reformation in Appenzell. The early reformers had the most success in the outer "Rhoden", a term that in the singular is said to mean a "clearing," and occurs in 1070, long before the final separation. Following the initial small success, in 1523 Joachim von Watt (also known as Joachim Vadian) began to preach the reformed version of the Acts of the Apostles to friends and fellow clergy. His preaching brought the Reformation into the forefront of public debate. In October 1523, the Council supported the Protestant principle of scriptural sermons and on 24 April 1524 Landsgemeinde confirmed the Cantonal Council's decision. However, the work of the Anabaptists in the Appenzell region (as well as in Zurich and St. Gallen) in 1525 led to government crackdowns. The first police action against the Anabaptists took place in June 1525, followed by the Anabaptist Disputation in Teufen in October 1529.
