Byzantine Iconoclasm was a significant period in the history of the Byzantine Empire during the 8th and 9th centuries, characterized by the conflict over the use of religious images, or icons. Supporters of iconoclasm believed that these images could lead to idolatry, while opponents, known as iconodules, argued that icons were essential for worship and teaching. The controversy led to several imperial edicts banning the use of icons, resulting in the destruction of many religious artworks. The movement eventually waned, and the veneration of icons was restored in 843, marking the end of the iconoclastic period and the reaffirmation of their importance in Orthodox Christianity.
