Iconoclasm is the deliberate destruction within a culture of the culture's own religious icons and other symbols or monuments, usually for religious or political motives. People who engage in or support iconoclasm are called "iconoclasts", Greek for "breakers of icons" (), a term that has come to be applied figuratively to any person who breaks or disdains established dogmata or conventions. Conversely, people who revere or venerate religious images are derisively called "iconolaters" (). They are normally known as "iconodules" (), or "iconophiles" (). These terms were, however, not a part of the Byzantine debate over images. They have been brought into common usage by modern historians (from the seventeenth century) and their application to Byzantium increased considerably in the late twentieth century. The Byzantine term for the debate over religious imagery, "iconomachy," means "struggle over images" or "image struggle".
