Iconoclasm: The Destruction of Religious Images From Byzantium to the Present

In the summer of 1566, mobs swept through the Netherlands in a two-week spree of destruction that art historians now call the Beeldenstorm, the "statue storm." They smashed statues, burned paintings, stripped altarpieces, and whitewashed church walls. At Antwerp alone, the interiors of thirty churches were destroyed in two days. What drove these people was not random vandalism. It was iconoclasm, and it is one of the most powerful forces ever to shape, unmake, and reshape the visual art of the world.

Iconoclasm is the deliberate destruction of religious or sacred images, usually motivated by the belief that such images constitute idolatry. The word comes from the Greek "eikon" (image) and "klasmos" (breaking). It is not a single event but a recurring phenomenon that has surfaced across centuries and cultures, from 8th-century Byzantium to the Protestant Reformation to the Taliban's destruction of the Bamiyan Buddhas in 2001. Each wave of iconoclasm has erased vast quantities of art, and each has also, paradoxically, generated new kinds of art in response.

This entry covers what iconoclasm is, its major historical episodes, what was lost, what survived, and how the debate over religious images continues to shape art today.

What Is Iconoclasm?

Iconoclasm is the rejection and destruction of images held sacred. It can be directed at paintings, sculptures, mosaics, manuscripts, or any visual representation deemed idolatrous or theologically dangerous. The term applies most precisely to religious image-breaking, though scholars have extended it to political and cultural contexts, like the toppling of statues during revolutions or the removal of Confederate monuments in the United States.

The Oxford University Press bibliography on iconoclasm in the Reformation era notes that the word "denotes the deliberate destruction or defacement of religious images and sacred vessels, in particular in the context of Christian worship." Read the full reference at Oxford Bibliographies. The motivations are always more than theological. Political power, social grievance, and economic resentment fuel iconoclastic movements as much as doctrinal conviction does.

Iconoclasm matters to art history for a simple reason: it is the greatest destroyer of art that has ever existed. Wars, fires, and floods have taken their toll, but iconoclasm is systematic. It targets the most expensive, most visible, and most revered artworks in a society. Understanding iconoclasm means understanding what was destroyed, what the destroyers believed, and what replaced the lost images.

Byzantine Iconoclasm (726-843)

The first and most studied episode of iconoclasm took place in the Byzantine Empire. Beginning around 726 under Emperor Leo III, a campaign against religious images was launched that would last, with a brief interruption, for over a century. Leo III ordered the removal of the icon of Christ from the Chalke Gate, the ceremonial entrance to the imperial palace in Constantinople. The act provoked riots.

The Byzantine iconoclasm is divided into two phases. The First Iconoclasm lasted from approximately 726 to 787, when the Second Council of Nicaea restored the veneration of icons. The Second Iconoclasm began under Leo V in 815 and lasted until 843, when icons were permanently restored, a date still celebrated in the Eastern Orthodox Church as the "Triumph of Orthodoxy."

What was destroyed during this period is difficult to know precisely, because iconoclasts were thorough. Mosaics were scraped from church walls and replaced with crosses or geometric patterns. Panel paintings of saints were burned. The few surviving icons from before the iconoclast period, like the 6th-century encaustic icon of Christ Pantocrator from Saint Catherine's Monastery at Sinai, survived because they were in remote locations beyond imperial reach. The Cambridge University Press study Byzantium in the Iconoclast Era c. 680-850 by Leslie Brubaker and John Haldon challenges the traditional assumption that iconoclasm resulted in wholesale destruction, arguing instead that the reality was more complex.

The theological debate centered on whether venerating an image amounted to worshipping the image itself, which would violate the biblical prohibition on graven images. Iconophiles, led by figures like John of Damascus (c. 675-749), argued that veneration passed through the image to the person it depicted. The iconoclasts held that the image was the idol, period. This was not a minor theological quibble. People died for both sides of this argument.

The Protestant Reformation (1520s-1600s)

The second great wave of iconoclasm came with the Protestant Reformation. As reformers like Martin Luther, Ulrich Zwingli, and John Calvin challenged the authority of the Roman Catholic Church, the veneration of religious images became a flashpoint. Catholic churches across Europe were filled with statues, paintings, reliquaries, and stained glass. Protestant reformers saw these as idolatry.

The first major iconoclastic riots of the Reformation occurred in Basel in 1529, when Protestant mobs stripped churches of their images. Similar events followed in Zurich, Strasbourg, and other Swiss and German cities. The Beeldenstorm of 1566 in the Netherlands was the most destructive single episode. As the Oxford Bibliographies reference notes, iconoclastic riots also occurred in Denmark (1530), France (1560s), and England under Henry VIII and later Edward VI and Elizabeth I.

England's iconoclasm was particularly thorough. Under Henry VIII, the dissolution of the monasteries (1536-1541) led to the destruction of monastic art across the country. Under Edward VI (1547-1553), a more doctrinally Protestant campaign removed images from parish churches. During the English Civil War, Puritan iconoclasts attacked parish churches again in the 1640s, smashing stained glass and defacing statues. John Phillips's study The Reformation of Images: Destruction of Art in England, 1535-1660 documents this sustained assault on religious art over more than a century.

What was lost is staggering. English parish churches once held wall paintings, rood screens, statues, and stained glass that had accumulated over centuries. The vast majority of medieval English religious art was destroyed. What survives today is often fragmentary: a few wall paintings uncovered under later whitewash, a handful of statues hidden in attics, some stained glass preserved in private chapels.

Modern and Ongoing Iconoclasm

Iconoclasm did not end with the Reformation. The French Revolution saw the systematic destruction of religious and royal imagery. Revolutionary mobs toppled statues from cathedral facades, melted down royal monuments, and smashed the gallery of kings at Notre-Dame de Paris, believing them to be French kings rather than biblical kings of Judah.

In the 20th century, the Cultural Revolution in China (1966-1976) targeted religious and cultural artifacts on a massive scale. The Taliban's destruction of the Bamiyan Buddhas in Afghanistan in March 2001 was one of the most widely condemned acts of iconoclasm in modern history. Two colossal Buddha statues, carved into a cliff in the 6th century, were demolished with explosives after the Taliban declared them idolatrous. The Cambridge study on iconoclasm East and West traces the connections between these modern movements and their historical predecessors.

Political iconoclasm continues today. The removal of Confederate monuments in the United States, the toppling of Soviet statues after 1989, and the destruction of colonial-era monuments in Africa and Asia are all forms of iconoclasm, though the term is debated in these contexts. The underlying dynamic is the same: a society rejects the values embodied in its public images and destroys them.

Iconoclasm and Related Terms

Iconoclasm connects to several other concepts in art history. The iconography of religious art, the study of how sacred images carry meaning, is inseparable from the iconoclast debate. The destruction of images during the Reformation is part of the broader history of Baroque art, which was partly a Catholic response to Protestant iconoclasm through the creation of new, emotionally powerful religious art. Byzantine art is defined in part by the iconoclast period that interrupted its development. The stained glass tradition in Northern Europe was nearly extinguished by Reformation iconoclasm. Fresco cycles in churches were frequently whitewashed over during iconoclastic campaigns, and some have been recovered in modern conservation work.

What Iconoclasm Teaches Us About Art

Iconoclasm reveals something uncomfortable about art: images carry power, and that power can be feared. The iconoclasts were not wrong to think that a painting or statue could move people, shape belief, and command devotion. They were reacting to something real. The question is whether that power is dangerous or whether it is the whole point of making art in the first place.

The paradox of iconoclasm is that it generates art as much as it destroys it. The Byzantine iconophile response produced some of the most revered icons in Eastern Orthodoxy. The Catholic Counter-Reformation, responding to Protestant image-breaking, commissioned the dramatic, emotionally charged art of the Baroque period. Caravaggio, Rubens, and Bernini all worked within this context of renewed Catholic patronage. Without iconoclasm, the art that replaced it would not exist in the form it does.

If you want to see what iconoclasm destroyed, visit the churches that survived it. Saint Catherine's Monastery at Sinai holds the earliest surviving Christian icons. The churches of Ravenna, in Italy, preserve Byzantine mosaics from before the iconoclast period. In England, the few surviving medieval wall paintings in parish churches give a glimpse of what was lost.
