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 the 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.
