Beeldenstorm in Dutch, roughly translatable to "statue storm", or Bildersturm in German ("image/statue storm"), also the Iconoclastic Fury, is a term used for outbreaks of destruction of religious images that occurred in Europe in the 16th century. During these spates of iconoclasm, Catholic art and many forms of church fittings and decoration were destroyed in unofficial or mob actions by nominally Calvinist Protestant crowds as part of the Protestant Reformation. Most of the destruction was of art in churches and public places.
