Regarding the False Charge of Insurrection Which has Unjustly Been Made Against Him." It also contained a preface by Luther. In March, Katharina, Luther's wife, became godmother to one of Karlstadt's children. Karlstadt was not allowed to preach or publish, and supported his family as a farmer and peddler near Wittenberg until 1529. Iconoclasm and Marian views Some of the Protestant reformers, in particular Andreas Karlstadt, together with Huldrych Zwingli and John Calvin encouraged the removal of religious images by invoking the Decalogue's prohibition of idolatry and the manufacture of graven images of God. As a result, religious statues and images were destroyed and damaged in spontaneous individual attacks as well as unauthorised iconoclastic riots. Erasmus described in a letter of 1529 such a riot that had occurred in Basel: Karlstadt has been seen as closely associated with "Bildersturm" (see Beeldenstorm), as he was at the time. In 1522, he convinced the Council of Wittenberg to order the removal of a number of images from the local churches, which had "catastrophic consequences." Martin Luther distanced himself from these actions. On March 12, 1522, Karlstadt spoke about Marian pictures, which were venerated at the time, and urged that they all be removed. Special aim was taken at Marian pictures visited in pilgrimages, but he also called for the removal of all public religious imagery and symbols. He asked for the destruction of Marian shrines such as the church Mary the Beautiful in Regensburg. Karlstadt was supported by Martin Bucer, Huldrych Zwingli and John Calvin. Yet this was more than a local German event. Significant iconoclastic riots took place in Zürich (in 1523), Copenhagen (1530), Münster (1534), Geneva (1535), Augsburg (1537), and Perth (1559). The Seventeen Provinces (now the Netherlands and Belgium and parts of northern France) were hit by a large wave of Protestant iconoclasm in the summer of 1566. In the Netherlands this is called the "Beeldenstorm" and began with the destruction of all the images of the Monastery of Saint Lawrence in Steenvoorde after a "Hagenpreek" (field sermon) by Sebastiaan Matte, and the sacking of the Monastery of Saint Anthony after a sermon by Jacob de Buysere. The "Beeldenstorm" is often held to mark the start of the Dutch Revolt against the Habsburg rulers of the Netherlands, although the fighting did not begin in earnest for some years.
